That's assuming that the controller card is set
to the standard address
of C800. C800 is the default for PCs but the cards can be addresses to
different addresses. Checkit is handy for finding the card address. Also
the code doesn't usually start right at the biginning of the ROM. It
starts
at an offset of 5 in most controllers so you'd use
debug then "g c800:5".
I've seen a couple of controllers that started at 2 and I think I remember
one that started at 10.
I've got an 8 bit Adaptec RLL card here tha uses C800:ccc to get it started,
all the rest (including other Adaptecs I have) use 5. Still love tht card
though, lot's of extras built into the BIOs format utility :-)
