# be SCSI and have unit number (BIOS_drive_number - BOOT_HD_BIAS). E.g.,

|
# BOOT_HD_BIAS=1 makes BIOS drive 1 correspond to 1:da(0,a) instead of

|
# 1:wd(1,a). If `da' is given explicitly, then the drive is assumed to be
|
|
# SCSI and have BIOS drive number (da_unit_number + BOOT_HD_BIAS). E.g.,
|
|
# BOOT_HD_BIAS=1 makes da(0,a) correspond to 1:da(0,a) instead of 0:da(0,a).
