36# Bias the conversion from the BIOS drive number to the FreeBSD unit number
37# for hard disks.  This may be useful for people booting in a mixed IDE/SCSI
38# environment (set BOOT_HD_BIAS to the number of IDE drives).
39#CFLAGS+=	-DBOOT_HD_BIAS=1
40#
41# Details: this only applies if BOOT_HD_BIAS > 0.  If the BIOS drive number
42# for the boot drive is >= BOOT_HD_BIAS, then the boot drive is assumed to
43# be SCSI and have unit number (BIOS_drive_number - BOOT_HD_BIAS).  E.g.,
44# BOOT_HD_BIAS=1 makes BIOS drive 1 correspond to 1:da(0,a) instead of
45# 1:wd(1,a).  If `da' is given explicitly, then the drive is assumed to be
46# SCSI and have BIOS drive number (da_unit_number + BOOT_HD_BIAS).  E.g.,
47# BOOT_HD_BIAS=1 makes da(0,a) correspond to 1:da(0,a) instead of 0:da(0,a).
