Just built a new system:
  Asus A7N8X-E motherboard, Athlon XP 2600+
  2 SATA seagate drives
  Old buslogic SCSI controller with 2 drives, a cd, and a tape.
  ATI compatible radeon 9000 agp 4x video card

The scsi disks have win nt images on them, from a previous system
so I can continue running it until I get a new one with both freebsd
and nt going off the sata drives.  When booted, the nt system runs fine.

I configured the mobo to boot from cd first, popped in the freebsd
4.10 cd.  However, it boots the nt images off the scsi disks instead.

So I unplugged the power from the scsi disks.  It still wouldn't
boot off the scsi cd.  Is the mobo bios too dumb to recognize a
scsi cd?

So I popped in a 4.10 boot floppy and tried again.
Turns out the boot floppy was bad,

Boot: 0:fda(0,a)/floppy

I tried to force a boot from the cd, but I'm not sure what to use
for the bios device and the device ids.  The CD is configured as
SCSI device 6.  I tried:

Boot: 1:da(6,a)/kernel -C
Invalid label
Invalid label
No /kernel

BIOS shows the following devices:

                                           ACPI controller           9

The device on pci1 at 6.0, irq 11 is the buslogic scsi controller.

So I made new boot floppies, which booted properly.
The boot and initial probe shows the following:

BIOS drive A: is disk0
BIOS drive C: is disk1
BIOS drive D: is disk2
BIOS drive E: is disk3
BIOS drive F: is disk4

(makes sense, given that the system has a floppy (A),
two scsi disks (C,D or E,F) and two sata disks (ditto).)

Freebsd isn't recognizing
  the buslogic controller (bt0) device (pci1, device 6.0),
  the sata device (pci1 device 11.0),
  or either of the network devices (pci0 device 4.0, pci1 device 4.0).
Any ideas why not?

I went ahead and started the installation process, figuring I could at
least configure the SATA drives, but when I went to do the fdisk I was
informed there weren't any disks on the system.

I tried pulling the scsi adapter to see if the irq conflict was the
problem, but it made no difference.  The boot showed three disks
instead of five, but the install still failed to get off the ground
because it said there weren't any disks.

Does anyone have experience with this motherboard, in particular using
sata drives?  Any ideas what's going on, and how to proceed?
I was hoping this was going to be relatively painless :-(

Assuming the bt0 device is recognized, what is the right thing to
feed boot to boot from the CD (scsi device 6)?

One other question.  The 5 pci slots have shared irqs, and the mobo
docs say if the drivers for the devices installed in the pci slots
don't support shared irqs, then the slots have to be allocated / left
unused so that only one device is present for each shared set.  Do
the freebsd drivers support shared irqs?

Do I need to bag 4.10 and go with 5.3 to get this to work?

Thanks for any insights.
