The POST says 1024k base, 48128KB extended (?), and 256k cache. (The
message flashes by so fast I can't catch what exactly it's saying.)

BIOS says System Memory 640KB, Extended Memory 47MB, Cache Size 256KB,
Shadow RAM 384KB; System ROM F000h-FFFFh. The video card also has
1024KB of memory (obviously?)

If it matters at all, BIOS also tells me, under Product Data:

  Machine Type/Model          8640MY0
  Flash EEPROM Revision Level BUKT10AUS
  System Board Identifier     13LLN2AD48R
  System Serial Number        553L2D8
  BIOS Date                   10/27/95

The 256KB cache is enabled, the PCI slot interrupts (#1 and #2) are
set up on "auto-select" (should I do this by hand? I get to choose the
IRQs myself if I want to) and I've basically disabled all the ROM
shadowing (not a lot of it was enabled anyway; I think I turned off
the video shadowing but all the others were already disabled).

I looked at it briefly but I'm not a glutton for hardware
documentation. If there's something I absolutely need to have I'd
appreciate a pointer. Thanks :-)

I'll try to figure this out.

Thanks for your incredibly fast response!
