Reviving this thread due to another oddity I discovered about this board (rev 2.1) where 512KB cache does not work using the jumper settings in the manual.

For a 4x 1024kbit chip configuration + 256kbit TAG I had to use:
JS1 2-3
JS2 2-3
JS3 1-2 --> NO JUMPER
JS4 1-2 3-4

Anyone else seen this issue?

Also, what are the proper CPU jumper settings for an AMD 5x86-133 ?
I used the "Intel P24D and AMD Enhanced Am486 Settings" from the manual with the JC8 jumpered to 2-3 to get the chip to 133MHz (quadrupled 33MHz).
Is this right?
