Ok that ouput helps.. the funciton "configure()" in main() is returning...
details of hard drive size (capactiy heads,track,etc.) missing...
Problem is probably in asc.c (ncr pica driver)...one possibility
in asc.c checking is done for 'magnum' notes in code refer
to magnum as "NEC M403" is that what you have??
The reason I am asking is for "M403" two things are
tested for and handled differently from "Acer_Pica_61"
1. dma
2. "Scsi Clock" Nec M403 has 40mhz pica has 25mhz
I noticed in the source code a possible clue, a mention
is made of  "Feature enable bit for 53CF94". You might
want to pull the cover and see what type of chip you have !!
It is possible two slightly different machines maybe reporting
the same cpu type via the arcbios.... I have already seen
that for NEC RiscServer 2200 and Nec RiscServer Express.
