I don't think it's a question of the boot blocks. It's a matter of the BIOS chosing the IDE(s) as drives 0x80 and 0x81, and trying to boot only off drives 0 and 0x80. However, you could disable the IDE(s) in the BIOS and should get the SCSI adapter hook its drives with SCSI ID(s) 0 and 1 in place for the BIOS drives 0x80 and 0x81. You won't be able to use the IDE(s) from DOS then, but it should be possible to use them from FreeBSD. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
