Im having some issues. I think it might be Video Card related. Not being able to handle a 66mhz FSB.
I had a similar issue with a VLB video card that couldn't handle 50mhz operation in a different 486

No Cyrix Enhancements turned on.
Cachechk reports 118 mhz and chkcpu reports 112.7
When I try and load doom2 I can play for a short time but then I get lines down the screen and it crashes back to dos - although you cant tell until you type "cls" and "mode 80" to get back to normal.
PCPBench crashes hard when I start it up.
Speedsys score is not so good either.
I was having this issue with the 256k normal cache and 32MB of RAM so its not them.
I have gone over a lot of the cyrix 5x86 reading material but what have I missed?
