The Adaptec bios is hard-wired to use port address 330.  I believe the
main reason for allowing alternate addresses is to support multiple boards
in one system.  The bios on the second board is not used since the bios
is meant to support only up to two drives (c: and d:).

I agree that it would be nice if they would support other addresses in the
bios.  I would also like to see Adaptec support more than two drives (in
a Dos environment) in a reasonable manner.  Their current driver that
supports users with more than 2 drives is incompatible with practically
every disk cache program that I've tried.
