Getting Started
Follow these steps to get you up and running as quickly as possible:
1. If running Windows 95, or Windows 3.1/3.11, insert the "Adaptec EZ-SCSI Setup Disk" into your floppy drive and run SETUP.EXE. Follow the instructions.

2. If running DOS, insert the "Adaptec EZ-SCSI Setup Disk" into your floppy drive, change to your floppy's drive letter, and run
INSTALL.BAT. For example:
C:\> A:
A:\> INSTALL <Enter>
Follow the instructions.


Hard Disk Support

Windows 95
Windows 95 includes built-in support for SCSI hard drives. If you attach a new, unformatted, drive to your SCSI host adapter, you will need to partition and format the media before you can use it.

You can follow these steps:
1. Run Device Manager. You can do this by moving the mouse pointer over "My Computer," clicking the right mouse button, and selecting the "Properties" menu option.
2. Select the "Device Manager" option.
3. Expand the "Disk drives" tree to view your SCSI hard drives.
4. Double-click on your newly added hard drive.
5. Select the "Settings" option.
6. If the "Int 13 unit" option is not turned on, then turn it on and select OK. Reboot your system.
7. Open up a DOS session (MS-DOS prompt).
8. Run FDISK to partition your new drive as you desire.
9. Reboot your operating system.
10. When Windows 95 comes back up, double-click on "My Computer."
11. Move the mouse pointer over your new drive letter(s), click the right mouse button, and then select the "Format..." option.
12.) Follow the instructions to format your media.

Note: Under many configurations, steps 1-6 are not required as Windows 95 may have already marked your new disk drive as an "Int 13 unit." We still recommend that you take these steps to ensure that your system is properly configured.

Windows 3.1/3.11 and DOS
DOS and Windows 3.1x include built-in support for SCSI hard drives if your new drive is under BIOS control (e.g. you booted from it). Please referto your host adapter documentation to learn more about whether or not your SCSI host adapter includes an on-board ROM BIOS. In this case, you can follow these steps:

1. Boot to DOS.
2. Run FDISK to partition your new drive as you desire.
3. Reboot your operating system.
4. Run FORMAT on your newly created drive letter(s)

If your new SCSI hard drive is not under BIOS control, you can follow these steps:
1. If running Windows 3.1x, install Adaptec EZ-SCSI for Windows 3.1x
- Insert the Adaptec EZ-SCSI 4.0 Setup Disk
- Run SETUP.EXE
2. If running DOS, install Adaptec EZ-SCSI for DOS
- Insert the Adaptec EZ-SCSI 4.0 Setup Disk
- Run INSTALL.BAT
3. After installing either Adaptec EZ-SCSI for DOS/Windows, reboot your system.
4. If you are running DOS, run AFDISK.EXE which is located in your Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI). If you are running Windows, you can use WINPART.EXE which is a Windows 3.1x partitioning utility.
5. Partition your new media as you desire.
6. Reboot your operating system.
7. At this point, your new drive is under ASPIDISK.SYS control (Adaptec's disk driver for DOS).
8. Although optional, we recommend that you run DOS FORMAT on your new drive letter(s) so that the drive can be scanned for defects.

Removal Media Support

Windows 95
There are a number of ways to prepare your removable media for use under Windows 95.

Windows 95, by default, will allocate one drive letter for your removable media device. You can see the icon by double-clicking on "My Computer" and seeing the "Removable Disk" text just below the drive's icon. If you wish to treat your removable media as one large floppy, simply insert the media into the drive and double-click on the icon. Windows 95 will automatically detect that the media is unformatted and ask you if you would like to format the media.

Windows 95 also allows you to use partitioned removable media. For example, if you have a 1 GByte removable cartridge, you might want to partition the media into two 512 MByte partitions. To create a partitioned removable media, you can follow these steps.
1. Run Device Manager. You can do this by moving the mouse pointer over "My Computer," clicking the right mouse button, and selecting the "Properties" menu option.
2. Select the "Device Manager" option.
3. Expand the "Disk drives" tree to view your SCSI removable hard drive.
4. Double-click on your newly added removable hard drive.
5. Select the "Settings" option.
6. If the "Int 13 unit" option is not turned on, then turn it on and select OK. The "Removable" option should also be set. Reboot your system.
7. Open up a DOS session (MS-DOS prompt).
8. Run FDISK to partition your removable media as you desire.
9. Reboot your operating system.
10. If you want to reserve multiple drive letters for your removable media drive (e.g. multiple partitions), follow the next steps,
otherwise, skip to step #17
11. Run Device Manager. You can do this by moving the mouse pointer over "My Computer," clicking the right mouse button, and selecting the "Properties" menu option.
12. Select the "Device Manager" option.
13. Expand the "Disk drives" tree to view your SCSI removable hard drive.
14. Double-click on your newly added removable hard drive.
15. Select the "Settings" option.
16. In the "Reserved Drive Letters" area, you can select the starting and ending drive letters for your removable media device. Save settings and reboot your system.
17. When Windows 95 comes back up, double-click on "My Computer."
18. Move the mouse pointer over your new drive, click the right mouse button, and then select the "Format..." option.
19. Follow the instructions to format your media.

Note: Under many configurations, steps 1-6 are not required as Windows 95 may have already marked your new disk drive as an "Int 13 unit." We still recommend that you take these steps to ensure that your system is properly configured.

Below is additional information you may find useful:
o We recommend that you boot Windows 95 without a DOS removable media device driver (e.g. ASPIDISK.SYS). You can comment out such entries from your CONFIG.SYS and then reboot. We have seen Windows 95 incorrectly create two drive letters for the same device when a DOS removable media driver is resident. In addition, we have seen some configurations where Windows 95 wouldn't allow us to set the starting and ending drive letters when a DOS removable media device driver is resident.

Windows 3.1/3.11 and DOS
To prepare your removable media for use under Windows 3.1/3.11 and DOS, you can follow these steps.
1. If running Windows 3.1x, install Adaptec EZ-SCSI for Windows 3.1x
- Insert the Adaptec EZ-SCSI 4.0 Setup Disk
- Run SETUP.EXE
2. If running DOS, install Adaptec EZ-SCSI for DOS
- Insert the Adaptec EZ-SCSI 4.0 Setup Disk
- Run INSTALL.BAT
3. After installing either Adaptec EZ-SCSI for DOS/Windows, reboot your system.
4. If you are running DOS, run AFDISK.EXE which is located in your Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI). If you are running Windows, you can use WINPART.EXE which is a Windows 3.1x partitioning utility.
5. Partition your new media as you desire.
6. Reboot your operating system.
7. At this point, your new drive is under ASPIDISK.SYS control (Adaptec's disk driver for DOS).
8. Although optional, we recommend that you run DOS FORMAT on your new drive letter(s) so that the drive can be scanned for defects.

Below is additional information you may find useful:
o Adaptec EZ-SCSI supports both 512 byte/sector media and 1024 byte/ sector media.

o If you would like to reserve multiple drive letters for your removable media, you can use the /r command line switch. For example, if you would like ASPIDISK.SYS to reserve two drive letters for your removable media, you would have the following in your CONFIG.SYS:
device=c:\scsi\aspidisk.sys /d /r2

o Support for the Panasonic PD drive is also included. Note that you should leave this device jumpered in its default two LUN mode.

CD-ROM Support

Windows 95
Windows 95 includes built-in support for SCSI-2 CD-ROM drives and some SCSI-1 devices. If your host adapter already has its miniport loaded, Windows 95 will automatically detect and support your SCSI CD-ROM drive.

Windows 3.1/3.11 and DOS
Adaptec's CD-ROM driver for DOS/Windows, ASPICD.SYS, has been written to support any SCSI-2 CD-ROM drive and most SCSI-1 CD-ROM drives. Simply run Adaptec EZ-SCSI and the correct additions will be made to your CONFIG.SYS and AUTOEXEC.BAT.

Adaptec EZ-SCSI has been tested with CD-ROM drives from the following vendors:
AIWA
Compaq
Chinon
Denon
Goldstar
Hitachi
IBM
LMS
Matsushita
NEC
Panasonic
Nakamichi
Philips
Pioneer
Plasmon Data
Plextor
Ricoh
Sanyo
Sony
TEAC
Texel
Toshiba
Yamaha

Below is additional information you may find useful:
o The following drives do not directly support Photo CD:
Chinon CDS 431
Denon DRD 253
LMS (Philips) CM 214
NEC CDR 72
NEC CDR 74 (NOTE: 74-1 and 84-1 do support single-
NEC CDR 84 session Photo CD)

By adding /XAEMUL to the ASPICD.SYS command line, in your CONFIG.SYS, we will emulate support for single-session Photo CD on these drives.

o The following drives do not support parity:
NEC CDR 38
NEC CDR 55
NEC CDR 72
NEC CDR 73
NEC CDR 74 (NOTE: 74-1 and 84-1 do support SCSI parity)
NEC CDR 84
NEC CDR 210 (NOTE: 210P does support parity)

Please consult your host adapter documentation on how to disable parity support on your SCSI host adapter.

o The following jukebox CD-ROM drives are fully supported:
Nakamichi MBR-7
Pioneer DRM 600
Pioneer DRM 604X

A drive letter will be assigned for each CD. Other jukebox CD-ROM drives may require you to add /L to the ASPICD.SYS command line. You may also need to modify your LASTDRIVE statement in your CONFIG.SYS.

o Some older SCSI CD-ROM drives do not support synchronous negotiation properly. If you encounter problems using your CD-ROM drive, try disabling synchronous negotiation. Please refer to your host adapter documentation on how to do this.

Tape Drive Support

Windows 95
Adaptec EZ-SCSI Lite does not include a SCSI tape backup application for Windows 95. See the UPGRADE INFORMATION section to learn more about the full version of Adaptec EZ-SCSI.

Windows 3.1/3.11 and DOS
Adaptec EZ-SCSI does not include a tape backup package for DOS or Windows 3.1x.


CD Recordable Support

Windows 95
Adaptec EZ-SCSI Lite does not include CD Recordable application software for Windows 95. See the UPGRADE INFORMATION section to learn more about the full version of Adaptec EZ-SCSI.

Windows 3.1/3.11 and DOS
Adaptec EZ-SCSI for Windows 3.1/3.11 and DOS does not include software to allow you to write your own CDs. Adaptec's CD-ROM driver, ASPICD.SYS, does allow you to assign a drive letter to your CD Recordable drive. Third party applications, such as Incat's Easy CD Pro, allow you to master CDs under Windows 3.1/3.11.

Hewlett-Packard's driver for HP ScanJet II scanners is included with Adaptec EZ-SCSI. This driver is named SJIIX.SYS and is designed to function with Adaptec's ASPI managers.

Installation of the driver is easy. Simply run Adaptec EZ-SCSI. Adaptec EZ-SCSI automatically detects your HP scanner and installs SJIIX.SYS into the appropriate section of your CONFIG.SYS file. You can then install HP's DESKSCAN software if it is not already installed.

Epson Scanner Support
To connect your PC system with the SCSI interface on an Epson scanner, first install an Adaptec SCSI Host Adapter interface board and EZ-SCSI software onto your PC system before loading the Epson Scanner Utility and TWAIN driver. The Epson scanner TWAIN driver should be included with your Epson scanner.

Other Scanners
Most scanners support the ASPI interface. Contact your scanner vendor to determine if their scanner and software support ASPI.

32-BIT SUPPORT FOR WINDOWS 3.1/3.11
Adaptec EZ-SCSI includes 32-Bit Disk Access support for Windows 3.1, Windows 3.11, and Windows for Workgroups 3.11. To enable this support, simply run the "32-Bit Disk Access" utility (FASTSCSI.EXE), and follow the instructions. Please note the following:
o Our 32-Bit Disk Access device drivers only support Adaptec's bus-mastering line of SCSI host adapters and Adaptec's AIC-6360/6370 based SCSI host adapters. These host adapters use the following ASPI managers:

ASPI2DOS.SYS
ASPI4DOS.SYS
ASPI7DOS.SYS
ASPI8DOS.SYS
ASPIEDOS.SYS

If your host adapter does not use one of these ASPI managers, our 32-Bit Disk Access utility will still allow you to enable or disable SCSI write caching.

o If you are running Windows for Workgroups 3.11, and you are not able to get 32-Bit File Access to work properly, the following comes from Microsoft's Windows for Workgroups resource kit:

"32-bit File Access will not enable on a drive on which there are open files during the initialization process of 32-bit File Access. Because of this, 32-bit file access cannot be enabled through the Control Panel Virtual Memory dialog when using a temporary swap file. The temporary swap file is opened before 32-bit File Access initializes and 32-bit File Access will not be able to enable on the drive where the temporary swap file is located. There normally should not be any open files at the time when 32-bit File Access is initializing. If there are open files, they are probably the result of some real mode TSR or a 3rd-party VxD."

o When 32-Bit Disk Access is enabled, you need to have the latest WINASPI.DLL file in your Windows' SYSTEM subdirectory. If an older revision is being used, you will experience protection faults when running "ASPI for Windows" applications. EZ-SCSI 3.11 (and later) will automatically install the correct WINASPI.DLL file. There are, however, a few older packages that install the older WINASPI.DLL file. If you are experiencing protection faults, while running "ASPI for Windows" applications, you should check the date of WINASPI.DLL in your Windows' SYSTEM subdirectory. If it is dated 1995 or later, you have the correct file.

o 32-Bit Disk Access, in general, does not significantly improve performance under Windows 3.1 or Windows 3.11. To get optimal disk performance, you should use Windows for Workgroups 3.11 which, in addition to 32-Bit Disk Access, includes support for 32-Bit File Access. We are seeing the larger performance gains by enabling 32-Bit Disk Access, 32-Bit File Access, and SCSI write caching.

o Our 32-Bit Disk Access driver cannot be used if you are also using our SCSI Power Management driver. If you attempt to load both drivers, an appropriate error message will appear when you run Windows. If you encounter this message, and if you prefer 32-Bit Disk Access over SCSI Power Management, simply run Adaptec's 32-Bit Disk Access utility and select the "Install" option. It will detect the conflict and remove the SCSI power management device driver.

o 32-Bit Disk Access only supports drives under BIOS control (INT 13h drives). This does NOT include drives under the control of ASPIDISK.SYS. Most of our SCSI host adapters allow you to have up to 8 SCSI drives under BIOS control.

o There is a known problem in Windows 3.1 and Windows 3.11 (does not affect Windows for Workgroups 3.11) in that its 32-Bit Disk Access solution only supports up to two hard drives. For example, if you have three hard drives under BIOS control, only the first two would be under 32-Bit Disk Access. If you encounter this situation, you can upgrade to Windows for Workgroups 3.11 which does not exhibit this limitation.

o Adaptec's 32-Bit Disk Access utility provides an uninstall option that will remove our 32-Bit device drivers. If you would like to manually remove the drivers, remove the following entries from the [386Enh] section of your SYSTEM.INI file:

device=fastscsi.386
device=aha1540.386
device=aha1740.386
device=aic7770.386
device=aic7870.386
device=aic6x60.386

(NOTE: Not all of these drivers will be present in your SYSTEM.INI file. Depends on what type of host adapter you have.)

o Enabling SCSI write caching can improve the overall performance of your system. Many SCSI hard drives ship factory default with SCSI write caching disabled. Our 32-Bit Disk Access utility will allow you to enable or disable SCSI write caching on a per device basis. We have found a few older drives causing system hangs, under intense disk I/O, when write caching is enabled. In the unlikely event that you encounter this situation, you can disable SCSI write caching at any time by running our 32-Bit Disk Access utility.

o On some systems, when you enable 32-Bit Disk Access, Windows' Control Panel incorrectly loads the IDE 32-Bit Disk Access driver even if you only have SCSI disk drives. This will typically result in an error message, while loading Windows, similar to the following:

"The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded on this computer because of interrupt conflicts."

If you encounter this, simply remove the line "device=*wdctrl" from the [386Enh] section of your SYSTEM.INI file. Another option is to run our 32-Bit Disk Access utility. It will detect that your configuration is incorrectly loading the IDE device driver and ask if you would like us to remove it.

o For the technical user: If you select to turn on SCSI write caching, we will also turn on the AWRE (Automatic Write Reallocation Enabled) bit in the Read/Write Error Recovery Page. If you select to turn off SCSI write caching, the AWRE bit is set back to the factory default setting (some drives ship factory default with AWRE set).

o If you have an AVA-2825 or AHA-1520A/1522A, with BIOS support for floptical drives enabled, and you have a floptical drive connected to your system, 32-Bit Disk Access is not supported under Windows 3.1/3.11.

DOS ASPI Managers
Adaptec EZ-SCSI 4.0 includes a number of ASPI managers for Adaptec's family of SCSI host adapters. Below is additional information on some of Adaptec's ASPI managers.

ASPI2DOS.SYS
ASPI2DOS.SYS is Adaptec's ASPI managers for AIC-6260/6360/6370 based SCSI host adapters. Running Adaptec EZ-SCSI will automatically detect which host adapter you have installed, which ASPI manager needs to be loaded, and what the correct command line switches are.

o If you are using an Adaptec APA-1460 SlimSCSI, make sure you have PCMCIA Card & Socket Services installed BEFORE running Adaptec EZ-SCSI.

o If you have an IBM ThinkPad 360Cs or an IBM ThinkPad 755, and are using the Adaptec APA-1460 SlimSCSI, you need to move the following line to the last line inside your CONFIG.SYS file:

DEVICE=C:\EZPLY\$ICPMDOS.SYS

Note: If the directory for EZ-Play is different than the default, use that directory instead. The above line uses the standard directory as an example.

o If you have an APA-1460 (SlimSCSI) in your system and are installing ASPI2DOS.SYS manually, you will need to add the following command line switch to ASPI2DOS.SYS in your CONFIG.SYS file:

DEVICE = C:\SCSI\ASPI2DOS.SYS /D /PCMCIA /Z

o If you cannot suspend/resume properly on an AcerNote 735c, with an APA-1460 (SlimSCSI), you're probably experiencing an I/O conflict between the APA-1460 and your laptop. The AcerNote uses port 35F for video control. You'll need to manually exclude this I/O port. With SystemSoft Card and Socket Services, you can do this by editing the CSALLOC.INI file and adding the line:

ioexclude=35F

o If you are using the Gateway 2000 Colorbook laptop with an Adaptec APA-1460 (SlimSCSI), ASPI2DOS.SYS may fail during driver installation. If you encounter this problem, you will need to go into the motherboard CMOS setup utility and disable the "FastBoot" option.

o SCAM stands for "SCSI Configured AutoMagically." Without SCAM support, the user needs to set jumpers or switches to assign a unique SCSI ID to each SCSI device. With SCAM support, a host adapter can determine which SCSI IDs are not in use, and assign a free ID to a SCAM capable SCSI device. You can enable SCAM support by adding /SCAM+ to your ASPI2DOS.SYS command line. For example:

DEVICE = C:\SCSI\ASPI2DOS.SYS /D /SCAM+

This will work with any AIC-6260/6360/6370 based SCSI host adapter that does not have a BIOS enabled on the host adapter. If the host adapter has a BIOS, and it is enabled, the command line switch is ignored. If you have a SCAM capable BIOS (e.g. AHA-1530P), then you can enable or disable SCAM support by running SCSISelect.

NOTE: There are very few SCAM capable SCSI devices available today. Special firmware is required on the SCSI device. If you do not have such a device, there is no need to use the /SCAM+ command line switch.

ASPI8DOS.SYS
ASPI8DOS.SYS is Adaptec's ASPI manager for AIC-7850/7855/7870 based PCI SCSI host adapters. Running Adaptec EZ-SCSI will automatically detect which host adapter you have installed, which ASPI manager needs to be loaded, and what the correct command line switches are.

o If you have an Adaptec PCI SCSI host adapter installed in your system, and you have EMM386.EXE loaded from MS-DOS versions up to 6.2, your system might hang if loading the ASPI manager after EMM386.EXE. This has been fixed in the EMM386.EXE that ships with MS-DOS 6.22 and later. If you experience this problem, you will either need to load ASPI8DOS.SYS before EMM386.EXE, or upgrade to MS-DOS 6.22 or later. If the ASPI manager detects a conflict, a message will be shown explaining how to work around the problem. Other ASPI modules (e.g. ASPICD.SYS) can continue to be loaded high.

o There are several techniques for a driver to determine if its PCI SCSI host adapter is installed in your system. ASPI8DOS.SYS will determine which is the best method, and has been written to work around the EMM386.EXE problems discussed above. There are three command line switches you can use to force the ASPI manager to use a specific method. These are:

/MB - This command line switch will force the driver to use the PCI BIOS calls (INT 1Ah) to scan for PCI SCSI host adapters.
/M1 - This command line switch will force the driver to use the "Mechanism 1" method for scanning for PCI SCSI host adapters.
/M2 - This command line switch will force the driver to use the "Mechanism 2" method for scanning for PCI SCSI host adapters.

For example, if you want to force the ASPI manager to find your PCI SCSI host adapter using PCI motherboard BIOS calls, your CONFIG.SYS would be:

DEVICE=C:\SCSI\ASPI8DOS.SYS /D /MB

NOTE: Most PCI systems do not support all three methods for scanning for PCI cards. It is recommended that you let the ASPI manager determine which method is suitable.

o If you would like ASPI8DOS.SYS NOT to reset the SCSI bus, during driver initialization, you can use the /NORST command line switch. For example:

DEVICE=C:\SCSI\ASPI8DOS.SYS /D /NORST

If you would like ASPI8DOS.SYS to always reset the SCSI bus, during driver initialization, you can use the /RESET command line switch. For example:

DEVICE=C:\SCSI\ASPI8DOS.SYS /D /RESET

MA358.SYS
MA358.SYS is Adaptec's ASPI manager for its APA-358/358A parallel port SCSI host adapters. Running Adaptec EZ-SCSI will automatically detect which host adapter you have installed, which ASPI manager needs to be loaded, and what the correct command line switches are.

o MA358.SYS, by default, will automatically detect the type of parallel port you are using. You can use the /Mnm switch to force a specific mode, and to set the amount of time that the MiniSCSI "Fast" read and write cycles are delayed (parallel ports on some computers require delays). You must specify values for both 'n' and 'm'.

The 'n' specifies the amount of delay. Allowable values for 'n' are 0 through 7, with each number representing a 25-nanosecond (ns) increment. A value of 7, for example, adds an 875 ns (7x125) delay to the cycles. The default of 0 specifies no delays.

The 'm' parameter determines the mode. The allowable values are shown in the following table:

Value

Meaning of 'm'

0

Auto-detect mode (the default). Automatically detects the type of port and configures the APA-358/358A for EPP if that port is detected to support EPP mode, otherwise the port is set up as a standard parallel port.

2

Forces unidirectional mode.

4

Forces bidirectional mode.

8

Assumes EPP 8-bit bidirectional mode. For this to work, the parallel port must be set for EPP mode in the CMOS setup program or by configuring jumper settings on your EPP I/O card. For instructions on using the CMOS setup program, see your motherboard documentation. For instructions on configuring
jumpers on your EPP I/O card, see your EPP I/O card documentation.



For example, if your parallel port is configured for EPP mode, and you would like the default read/write delay, your CONFIG.SYS would contain the following:

DEVICE=C:\SCSI\MA358.SYS /m08

If you change the MA358.SYS options in the config.sys file, turn the computer OFF and then ON again to have the changes take effect. (Do not simply reboot the computer using Ctrl-Alt-Del.)

o If you have an original NEC Ultralite Versa laptop, and MA358.SYS is unable to detect the APA-358/358A SCSI host adapter, you should use the /m20 command line switch. For example:

DEVICE=C:\SCSI\MA358.SYS /m20

o If you are using the APA-358 with an NEC Versa E or Versa V system, which uses the Western Digital Super I/O chip for FPP Parallel Ports (Chip #WD76C30), you should use the MA358NEC.SYS ASPI Manager in your CONFIG.SYS file instead of the standard MA358.SYS ASPI Manager.

o If you are using an IBM ThinkPad 720 series computer, you should use the MA358IBM.SYS ASPI manager in your CONFIG.SYS file instead of the standard MA358.SYS ASPI manager.

o When using the APA-358/358A, you should not configure your parallel port for ECP mode. Instead, you should configure the port for EPP mode.

o MA358.SYS only supports one APA-358/358A in a system.

o If you are using the APA-358/358A, and you are backing up from a SCSI disk drive to a SCSI tape drive, and you are using SMARTDRV, we recommend that you disable SMARTDRV write caching. Leaving write caching enabled can cause the backup to fail.

WINDOWS 3.1x/DOS GENERAL TROUBLESHOOTING
o The ordering in which the Adaptec EZ-SCSI installer displays SCSI host adapters detected is dependent on a number of factors. If you have multiple SCSI host adapters, and the ordering displayed is not as you would expect, do not be alarmed. Adaptec EZ-SCSI will still properly edit your configuration files.

o SMARTDRV 5.0 (in MS-DOS 6.2, Windows for Workgroups 3.11) now includes caching for CD-ROM drives. There is a problem with SMARTDRV in its support for XA formatted Compact Discs. If you experience "Not Ready" errors, using SMARTDRV 5.0, add /E:2048 to your SMARTDRV command line. For example:

C:\DOS\SMARTDRV /X /E:2048

o You should install Adaptec EZ-SCSI to a drive letter that exists at boot time. This would NOT include RAM drives, network drives, removable drives, etc.

o We have seen at least one case where an unstable video driver would cause EZ-SCSI for Windows to hang during installation. If you are experiencing similar problems, try using the standard VGA driver that comes with Windows. If EZ-SCSI for Windows then installs properly, you may want to contact your video card company for updated drivers.

o In the unlikely event that you encounter a time-out failure when EZ-SCSI for Windows scans the SCSI bus, you should run EZ-SCSI for DOS first. Let it modify your CONFIG.SYS to load the appropriate ASPI managers; reboot your system. You should then be able to run EZ-SCSI for Windows.

o If you have an AHA-2740W/2742W or AHA-2940W (Wide SCSI Host Adapter), the SCSI Interrogator for Windows (SHOWSCSI.EXE) will only show icons for SCSI IDs 0-7. You will not see IDs 8-15.

o The SCSI Power Management Utility requires that the following line be present in your SYSTEM.INI file under the [386Enh] section:
device=VSCSIPWR.386

The first time you run SCSI Power Management you will be prompted to install the above driver. If you wish to disable the SCSI Power Management functions, you can remove this line from your SYSTEM.INI file in your WINDOWS subdirectory.

o An issue with EMM386.EXE from DOS 6.2, and earlier, can cause problems with PCI systems. The HIGHSCAN option can overwrite the PCI BIOS area on some PCI systems, making the PCI BIOS detection useless. If your Adaptec PCI SCSI host adapter is not detected, be sure to remove the HIGHSCAN option from EMM386.EXE in your CONFIG.SYS file.
