OS/2 Warp Installation Notes for Compaq Aero

What you end up doing is having multiple config.sys files. One for floppy use and another if you want to use some other pcmcia devices.

I also have a few others one for each of: floppy, normal, ethernet. It's a real pain in the ass but the ether drivers need the card to be inserted at boot time. (This is also the case for Windows.)

The essential method is this:

Perform a normal install without PCMCIA support. There is a window about 7 disks in that lets you change your monitor and turn on on PCMCIA support, etc. Simply set nothing at this stage.
After installation is complete and the system is up install PCMCIA support using Selective Install in the System Setup folder. I use the "Compaq Concerto" selection.
copy c:\config.sys c:\os2\boot\config.p
copy c:\config.sys c:\os2\boot\config.f

Remove or comment out these lines from \os2\boot\config.f

    BASEDEV=PCMCIA.SYS /P
    DEVICE=C:\OS2\MDOS\VPCMCIA.SYS
    DEVICE=C:\OS2\BOOT\AUTODRV2.SYS C:\OS2\AUTODRV2.INI
    BASEDEV=IBM2CMQ1.SYS /s0=2

Edit \os2\boot\altf1.cmd after the first "IF" line add something like this

    IF P==%1 GOTO bootpcmcia
    IF p==%1 GOTO bootpcmcia
    IF F==%1 GOTO bootfloppy
    IF f==%1 GOTO bootfloppy

Just before the last line in the file ":end", add something like this

    GOTO end
    :bootpcmcia
    copy c:\os2\boot\config.p c:\config.sys
    GOTO end
    :bootfloppy
    copy c:\os2\boot\config.f c:\config.sys
    GOTO end

Edit \os2\boot\altf1bot.scr, this is a text file that initially has nothing in it. Add something like this:
```
        p - pcmcia
        f - floppy
```
When the OS/2 line visible at the top left of the screen while booting you can press ALT-F1 to get access to the script you just changed. Press f to load the non-pcmcia version of config.sys, p for the other.
!!!NOTE!!! -- this means that when you install something that changes config.sys you will need to make these changes in \os2\boot\config.p and f.
