Solution:

When installing PCMCIA devices, Windows 95 OSR2 or Windows 98 will check the checksum of the PCMCIA card if it is match with the check in OEMSETUP.INF [Generic] %COMPAD.DeviceDesc%=COMPAD.Install, PCMCIA\ADVANTECH-COMpad-32/85-14ED For some COMpad-85, the checksum is not "14ED". The PCMCIA chipset used in COMpad-85 will be changed sometimes due to availably. We found different chipset will return different checksum. Different checksum other then "14ED" will result in installation failure. To solve this problem, we need to read the actual checksum, then modify the checksum in OEMSETUP.INF. To read checksum, please use attached DOS program DTPL.EXE under pure MS-DOS environment. 1. Extract the file "COM32-85.ZIP" and install it. After finish the procedure and reboot, you'll see below message. Configure card to: I/O port : 2E8-3EF, 3E8-3EF (upon your setting) IRQ number : 15 (upon your setting) Power : connected COMpad card is present in socket 1 2. Extract the file "CARDSOFT.ZIP" but not necessary to install it. And you must pay your attention on the path of the "CARDSOFT" software. 3. Refer below line to modify CONFIG.SYS to initialize the PCMCIA interface, so you should use a DOS Hard Disk to start the system. DEVICE=C:\DOS\HIMEM.SYS DEVICE=C:\DOS\EMM386.EXE NOEMS X=D000-DFFF DEVICE=C:\CARDSOFT\CARDSOFT\SS365SL.EXE DEVICE=C:\CARDSOFT\CARDSOFT\CS.EXE DEVICE=C:\CARDSOFT\CARDSOFT\CSALLOC.EXE DEVICE=C:\COMPAD\COMPAD.EXE /A1 /Q15 (upon your setting) 4. Run DTPL.EXE under DOS prompt like: dtpl -i You'll see the checksum information. One COMpad-85 in our checksum test is "F60D". Then modify OEMSETUP.INI like: [Generic] %COMPAD.DeviceDesc%=COMPAD.Install,PCMCIA\ADVANTECH-COMpad-32/85-F60D Enter Windows 95 or 98, use the modified OEMSETUP.INI for installation.
