Was any progress ever made with this? I just recently acquired two "2-1" cards which will configure just fine with the reference disk, but I can not get the 3com NDIS driver to load on them. It bombs out with an error about unexpected POS registers. Also the 3C527.EXE diag utility will not...
Seems pretty clear he wants to use the single activity LED provided by almost every PC chassis to reflect the activity of multiple different disk systems
Transportation did not cause this. The seller did a bait and switch. You did not receive the unit in the original photos, this should be adequate reason to force a return on any moderated sales platform
Actually here is a thought... that weitek FPU is memory mapped right? Try removing it. Perhaps the board is inserting wait states because of that thing
I guess. The L1 and L2 numbers here are really not bad but the main memory is still about half to one-third the speed it should be. It doesn't sit well with me but I don't know what else to suggest though.
Agree with this. I would go for the Mega Image32 card. The CDROM connector on it is most likely either set to ternary or disabled by default and should be able to be safely ignored without changing the rest of your IDE/IO cards' setup
I have never seen a wait state option being tied to cache chip size before, that's quite odd. You would want 32Kx8 since you have 256KB cache.
Looks like adjusting the settings helped marginally, but I think it's just a slow board.
De-turbo can be implemented in many different ways on 486...
OK cool I'll go through them 1by1
Hidden Refresh - enabled is faster but it can cause problems with some ISA video cards (notably tseng)
Slow refresh - enabled is faster, almost always works
single ale - don't know
master mode byte swap - don't know
AT wait state - disabled is faster

An 8-bit NIC is going to be limiting which IRQ it can use to something in the range of 2-7. The most combatible setting here would be to set the IRQ of the network card to 2. 3/4 will stomp on one of your serial ports and 5 is the preferred IRQ for audio. 6 is the floppy controller, and 7 is the...
1. pushing the turbo button makes things worse, so you obviously had it on the "fast" setting to begin with
2. the system has no ability to detect the speed of the memory you install, the speed is the same regardless of what you shove in there so you might as well keep all 20MB
3. cache speed...
AFAIK there were no cards other than disk controllers which could be configured to use that port. The rub is the both floppy and hard drive controllers BOTH use port 3F7 but different bits of the register. If you only have one single combination FDC/HDC in the computer a conflict is extremely...
