>Release:        FreeBSD 4.1-STABLE i386
>Organization:
>Environment:

	FreeBSD 4.x on i386 booting from IDE HDD without an fstab(5)
file.

>Description:

	When booting without an fstab(5) file, by default, the
kernel will try to mount the root device from a wd(4) device. However,
since the wd(4) have been depricated for ad(4), it should try to boot
from an ad(4) device.

>How-To-Repeat:

	Without any special settings in the /boot/loader.conf or other
customizations,

  # mv /etc/fstab /etc/fstab.hold
  # reboot
  .
  .
  .

  (After we go through the boot messages...)

  atapci0: <Generic PCI ATA controller> port 0xfe00-0xfe0f irq 14 at device 8.0 on pci0
  ...
  ad0: 775MB <IBM-DSOA-20810> [1575/16/63] at ata0-master WDMA2
  Mounting root from ufs:wd0s1a

Now, I fall into single-user where I repair the fstab and continue the
boot. When up in multi-user,

  # mount
  /dev/wd0s1a on / (ufs, local, soft-updates)
  /dev/ad0s1e on /usr (ufs, local, soft-updates)
  procfs on /proc (procfs, local)

The wd0 is still there.

When booted with the fstab,

  /dev/ad0s1a on / (ufs, local, soft-updates)

It appears as intended.

>Fix:

	I had a look in the boot code and found where the mount
information is printed from, /usr/src/sys/kern/vfs_conf.c, but trying
to track down where all that information comes from... That BIOS stuff
is not pretty.
