I did get the FPU version so that is not a problem. The problem is that I had a 486-50 so my kernel is currently configured for a 486 hence it won't boot on a 386 it seems. Moslty I was asking if FreeBSD had a patch to recognize the chip as a Nexgen chip instead of a 386. But since the NExgen chip doesn't support Pentuim microcode, it doesn't seem to matter. Although I d know Linux has a patch to let it take advantage of nexgens cache on steriods, does FreeBSD have something similar? I guess it is time to download boot floppies so I can fix my kernel... -Scott
