# Bias the conversion from the BIOS drive number to the FreeBSD unit number
# for hard disks.  This may be useful for people booting in a mixed IDE/SCSI
# environment (set BOOT_HD_BIAS to the number of IDE drives).
#CFLAGS+=	-DBOOT_HD_BIAS=1
#
# Details: this only applies if BOOT_HD_BIAS > 0.  If the BIOS drive number
# for the boot drive is >= BOOT_HD_BIAS, then the boot drive is assumed to
# 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:sd(0,a) instead of
# 1:wd(1,a).  If `sd' is given explicitly, then the drive is assumed to be
# SCSI and have BIOS drive number (sd_unit_number + BOOT_HD_BIAS).  E.g.,
# BOOT_HD_BIAS=1 makes sd(0,a) correspond to 1:sd(0,a) instead of 0:sd(0,a).
