4X PCMCIA CD-ROM Drive - Installation Problems

Applicable to: United States

Product Involved
1969008 4X PCMCIA CD Rom Drive
1969009 4X PCMCIA Stereo CD Rom Drive

When a customer cannot install the 4X PCMCIA CD Rom Drives, ensure that the CD Rom is the only PCMCIA card installed in the machine. If any other PCMCIA devices are being used, remove those PCMCIA cards during the installation of the 4X PCMCIA CD Rom Drives. This includes I/O cards, such as the PCMCIA Auto 16/4 TR Card (04H6922) or PCMCIA modem cards. If the system is using other PCMCIA devices and the cards are not removed from the PCMCIA socket when installing 4X PCMCIA CD Rom support, the CD Rom drive will not be seen correctly and will not install properly.

To install the CD Rom Drive, first remove other PCMCIA devices from the PCMCIA sockets. Ask the customer if the AC adapter is being used for the PCMCIA CD Rom drive, and that the drive has been turned on prior to installation.

If running Windows 95 with the Auto PCMCIA 16/4 TR Card, removethe TR Card prior to inserting the 4X CD Rom Interface Card and installing 4X CD Rom Support. Once the 4X PCMCIA Drive is recognized and running, reboot with the tokenring card inserted while the 4X PCMCIA Interface Card is removed. Once Win95 has started, insert the 4X PCMCIA Interface Card. Inform the customer that if the 4X PCMCIA Interface Card and TR Card (or other PCMCIA devices) are inserted at boot, the CD Rom drive will not be configured properly. The 4X CD Rom Drive will be recognized properly if its interface card is inserted after bootup.

Microsoft has documented the Token Ring issue in their Knowledge Base online support (http://microsoft.com, and searching using keywords of thinkpad and windows 95).

Development is working on this issue. Make a LENA case against the part number of the drive involved (1969008 or 1969009). Document the system that is involved (machine type, sub-model, and serial number), operating system involved, problem and error code, when the problem occurs, system configuration (other adapters/cards installed, setup of the adapters/cards, system RAM), and operating system/version being used.

Symptom:
The following PCMCIA Token Ring Cards may not work in systems with Windows 95.
- IBM Token Ring Credit Card Adapter
- IBM Token Ring Credit Card Adapter II

Cause:
Problem may be related to several conditions:
- The Token Ring adapter requires I/O address in the A20-A2F range.
- The system has sound support or other hardware devices using I/O port address of 220-22F.
- The Windows 95 I/O arbitrator pays attention to the first 10 bits of any I/O allocation. I/O allocation conflicts within a 10bit decode are registered by the system as having an I/O address conflict.

Resolution:
Manually configure devices using the following steps:
1. Double-click SYSTEM from Control Panel

2. Double-click "IBM Token-Ring Credit Card Adapter II or compatibles" from the Device Manager Tab.

3. Click the Resources Tab and note the resources the network card is using. To change a resource, click the Use Automatic Settings check box to clear it, click the resource, and then click Change Setting.
a. Change the IRQ setting so that it does not conflict with the IRQ used by any other device.
b. Change the first memory range to D4000-D5FFF. Change the second memory range to E0000-EFFFF. If these values conflict with another device, you may have to use different values. You must change them from the default 10000-11FFF ranges.
c. Click OK.
4. Double-click Sound, Video, and Game Controllers, and then double-click the sound card or the conflicting device.

5. Make sure that the Use Automatic Settings check box does not contain a check mark.

6. Click OK until you return to Control Panel.

7. Restart your system.
