	Hello all,

	I got Dell OptiPlex GXM 5100 sitting here - your plain
P100/24MB/1Gig IDE drive system. I compiled a custom kernel for it, and
now it started to crash (two times so far). I am pretty sure it is user
error. What am I missing? My kernel config file is attached below (sorry
it is so large). Thanks,
