You've done cache and A20

The other possibles, maybe you can lower the DRAM wait state from 2 to 1 or to 0 - run a memtest to see if it holds up at lower WS.
Decoupled refresh enabled may be better.

Shadow RAM = main - what other options - if "main + Video/vbios" then that would be much better for anything accessing the Vbios.
Alternatively, running UNIVBE may improve video operations.

PS. The way the BUS works, I can't see there being any disadvantage in a combo card - but a CL5428 is more advanced than a 5424, though most significantly in Windows acceleration .... couple of cheaper option on Intl shipping from Ukraine - a 5428 and a WD90c33 - a great Windows accelerator, don't know about DOS though - I remember these old cards mostly from putting them through WINTACH.

Ok...so I don't need a new vga card then? Yeeeesh. The conflicting information is driving me nuts. Maybe I need to just get a better motherboard. I don't know.

I've been informed that my cache is either fake or not working properly. Here's a cachecheck test I ran.

Looks like I'll be shopping for a new motherboard. Suggestions?

That is a horrible result - no secondary cache, and for some reason, the primary cache gives up after the first few MB.

what board is it, and are the jumpers listed - they could be mis-set - and are there empty cache sockets?
