On the old 386 era PCs you have to specify cyl/head/sector/lz type stuff
in the BIOS usually? It's possible to sub in a CF card on the IDE bus with
a cheap adapter, but I'm not sure how the cyl/head/sector stuff plays out.
Maybe go with something fairly small like 32MB and a CF to IDE adapter
(it's just wires, CF cards are similar to early PCMCIA which is ATA which
I think is just buffered ISA but I could have it wrong?)
I did this recently on a 486 but it had an auto-detect feature for the
hard drive parameters. Maybe they don't really matter when using a CF Card
-- does anyone know?
Another option is the ISA CF/IDE card from GlitchWorks. It has it's own
BIOS AFAIK and you don't need to worry about specifying the drive info in
the bios. I have 3 or 4 but haven't tried them yet.
On PCI systems Promise FastTrak IDE cards take care of the BIOS drive
specification annoyances -- I use a PATA IDE to SD card widget on a
FastTrak 100 on my Pentium luggable -- works well.
