Oh, the joys of SCSI... So it looks like I have two dead cables and/or terminators here, and I still don't know if the drive works :( Unfortunately my other SCSI controllers are a bit exotic (one EISA, the other a combi SCSI+IDE controller that hangs any system with other IDE controller). I have …

It's not worth the headache unless your targeting late dos games. I have a k6-3 for those. I moved my Athlon 700 to 2k just because 98se and Me kept screwing up every 3-4 months. On 2k now, the games I was playing before still work, buts stable now. I agree ! A soc775 is too much machine for Win9x. …

Nice case ! and MediaVision Pro Audio Spectrum 16 LMSI - I choose the latter The choice of a MV PAS is a good one imho. Very 1993-1994 ! Curious if your card is an OEM version ? Compaq used them in some builds and maybe P.Bell too iirc. I have a 650-0042-01k with the LMSI chips, and it has the …

Hmm you could not network print from XP even though there are drivers for XP ? That does not sound good. Are you sure your router is not part of the issue ? Possibly blocking some ports.. Just a thought as I do see Xp32 and XP 64 drivers for your printer which should allow network printing if …

None of the labels look familiar. Did you look on on the under side of them, maybe someone felt pen what they for on their bottoms (I do that with old roms). Yes a chip reader would be very handy !

The nearly same card at the vgamuseum shows 4 jumpers, yours has two plus a two hard wired ones near the 14Mhz XTAL.

I've had an idea, though. I know many BIOSes can be "unlocked"; that is, it is functionally the same BIOS but a few extra menus are unlocked. I've flashed an unlocked BIOS on my much more modern Dell Vostro 200, so maybe that's a possibility with a version of PhoenixBIOS this old. Yes it may be …

Nope that picture shows me exactly what I expected. There is no generic BIOS you will find for it. Reasons right off the bat: On-board Rage video, onboard audio and an unidentified support chip -- all circled in red. All would require support in the BIOS. Here is couple picture of different boards …

Have a few old Compaq boards from about the same era and they are very OEM specific. Not just the BIOS but the boards themself are made to Compaq specs (one requires a straight floppy cable, not one with a twist like standard as an example) so electrically very different from most retail boards. …
