If this is not the ASUS board, ignore me!!

I have qualified and done extensive testing on the ASUS Triton board, it
does work.  To this day I have probably completed over 100 make worlds
on these boards.  I see you are running a 100Mhz CPU chip, are you also
running 60nS DRAM as required by the motherboard book.  Have you left
the BIOS settings on the default values, or have you tried to speed
things up by tweaking them??
