    I have never used a 1540B but I vaguely remember that if you change
    the port address you can _no longer_ use the on board BIOS becuase it
    has the address 330 built in.  The error message you report rather
    looks to be as though the BIOS is complaining it cannot find the
    1540 - which is exactly what would be predicted.  AFAIK this
    inability to change the port and keep the BIOS working was one of
    the bugs that Adaptec sorted out when they designed the 1540C.

    You might try ftp.adaptec.com as I vaguely remember (sorry about all
    this being vague) that there are EPROM images there for the 1540B
    BIOS with different port addresses.
