Home and Away Credit Card Adapter - Windows 95 Tips
Applicable to: World-Wide
Note: This document comes from the HINTS Section - Tips, known problems, etc. of the HAWIN95.TXT file. 
Slot Preferences:
In some computers Windows 95 is unable to correctly identify the Fax-Modem-Ethernet PC Card in certain PCMCIA slots. If your Fax-Modem-Ethernet is not identified by name when the card is inserted for the first time, or if it is identified as an SRAM memory card, try another slot. Here are preferred slots for various computers:
IBM ThinkPad 755 (all models):
Preferred: Use slot B
Old Card and Socket Services:
Windows 95 comes with Card and Socket Services to enable PC Cards. However, some computers may have old Card and Socket Services already installed before being upgraded to Windows 95. If this is the case with your computer, you need to determine if the old Card and Socket Services are required.
- If you use no other PC Cards in your computer then the old Card and Socket Services are not required and you should remove them when enabling Windows 95 PCMCIA support through the control panel.
- If you use other PC Cards that previously ran with the old Card and Socket Services, try running them with Windows 95 services. Do this by enabling PCMCIA support, indicating that you want the old services removed when prompted, then seeing if Windows 95 configures your other PC Cards automatically. In some cases you may need to contact the other card vendor to obtain Windows 95 installation files, but in many cases the required files are already included with Windows 95.
- If you use other PC Cards and they *require* the old Card and Socket services, then you will not be able to use Windows 95 plug and play features.
Portable Option under Windows 95 Installation:
When you install Windows 95 you are given several installation profiles. If you selected "Portable" then you should have all of the support files required to enable your PCMCIA slots. If you did not install with the portable option then you may need to reinstall Windows 95. If you don't see the PCMCIA icon in the Control Panel then you may have this problem.
Improper RE-assignment of resources:
When the Fax+Modem+Ethernet card is installed properly all components of the card share resources. For example, the MultiFunction "parent" and the "modem" child device and the "network card" child device will all show up at the same interrupt in the Windows 95 Device Manager.
If you then insert another PCMCIA card that can ONLY run at the interrupt occupied by the Fax+Modem+Ethernet card, Windows 95 will move the Fax+Modem+Ethernet card to a new interrupt and give the original interrupt to the new card. This is dynamic reallocation of resources and is one of the features of Windows 95.
HOWEVER, Windows 95 may only move the parent MultiFunction device to the new interrupt, leaving the modem and network card children at the old interrupt, resulting in a resource conflict. The resource conflict will be shown in the device manager.
Workarounds:
1) Insert the other PCMCIA card first.
- The other card will acquire it's desired resources.
- Then insert the Fax+Modem+Ethernet card.
- The Fax+Modem+Ethernet card will configure around the first card, avoiding resource conflicts.
2) If you will be taking the other card in and out frequently you should reserve the desired resources through the device manager. Then the Fax+Modem+Ethernet card will always configure around the other card's resources, even when the other card is not installed.
Note: this is only a problem when using the Fax+Modem+Ethernet card with other cards that have very rigid resource requirements. For example, an older PCMCIA card that can only run at a single interrupt level.
