I don't know what you are referring to here.

We will use a different computer  This one requires a large PDF file to 
change the jumpers and I don't think it will even work with this CPU, 
which is designed for boards that do 2 x 75MHz.  We were given 9 DFI 
computers and 2 boards and moved things around between them to make some 
work, and goofed on this combination.  This board does multiples of 60 or 
66MHz, up to 233MHz (for AMD or Intel, for Cyrix only to 200 because Cyrix 
won't do non-integral multiples).

I have a board that does 2x83, with a 166MHz cpu in it.  We had to replace 
a dead serial port.

That will still not make the jumper settings correct for this cpu.
The kernel I used was based on the BL2 ramdisk kernel, with sound added.
