: I have upgraded my system from an AMD 486DX2-50 to a 486DX2-80 and am having
: problems. I do not blame them on my AMD chip, though. I have an ATI Graphics
: Ultra Pro board. Its the VLB model. I also have a VLB multi I/O board which
: has a caching IDE controller on it. In any case, these boards worked fine when
: the system was running at 25 Mhz, but now that it is at 40 Mhz, things are
: terrible. I've removed the Multi I/O card and replaced it with a 16bit board
: which does not cache. I think I will be buying a new motherboard soon. I
: think that its VLB is the problem.
: I guess the point is, you won't have problems with the 80 Mhz and Linux.
: You may have problems with the 80 Mhz and any VLB cards with the motherboard.
: From the readings I see on UseNet, I've noticed that other people have had
: problems with VLB combinations. My problems had occured in both DOS and
: Linux environments. I still have some problems in Linux when I run XV and
: try to do some color editing functions. Sometimes the system crashes when
: I start X. I tried upgrading to X11R6 (XFree86 3.1) and that did not help.
: Make sure you will have time to try out the motherboard before you decide
: to keep the system.

I think the ATI is your problem. The c't (a german computer magazin) claims that
all ATI chips (including Mach64) are only specified for a maximum frequency of
33 MHz. Hence your 40MHz VL bus overcharges the ATI. Maybe this is the reason
for your problems.
