Not exactly : a K6-200ALR with a TX97

Not when I use 64 Mb. It works fine with 32 Mb.

Same thing here.

I have tried with a Cyrix P200+, a P200, a P133, a P100, and 3 different K6 :
I get signal 11 errors with all K6 (tried all multipliers and bus speeds, even
50x2...) when the K6 uses 64 Mb, and none if the processor is not a K6 or the
uses only 32 Mb.

I have tried 4 motherboards (2 TX97, 1 TX97-XE and a Gigabyte with a HX
chipset) with the same result : K6 && 64 Mb <==> sig11

If I boot with mem=32M, the K6 works very well at 208 Mhz (on the TX97-XE,
with EDO), at 233 and 225 (on the TX97, with the SDRAM sold with the
motherboard).

I have also tried to tweak bios settings, to disable the write allocate
feature, to disable bus-mastering, to play with voltage settings, to
use 2.1.46 ;-), to use Redhat instead of Debian :-( and it does not change
anything.

The only thing that works a little is modify the kernel to allocate buffers
in the lower 32 Mb. But I still get a few seg11. Putting a 32 Mb ramdisk
in the upper 32 Mb works, but it is not fun :-(

The TX97-X is approved.

My K6-225 with only 32 Mb is quite faster than the PPro-200 with 64 Mb I
use at work, so I can't say no...
