Asus A7N8X-Deluxe with SCSI boot drives and PATA to SATA d..

Hi all

I have a problem with migrating my PATA drives to SATA on my
A7N8X-Deluxe board.

Researching before posting makes me think this a common problem and I
post in case this has been resolved.

Issue and setup
Motherboard as above with 1013 BIOS
I have an IBM SCSI controller hosting 2 x 36Gb SCSI drives as RAID 1
I have an Adaptec board running a DLT tape drive
I have 2 x PATA drives connected to the primary IDE channel
Originally installed Small Business Server 2003 with only SCSI drives
installed. Added PATA once OS was up and running - so MBR is located
on the SCSI drives.
This has run fine for 18 months or so.

On replacing the PATA for SATA drives, the system fails to boot. The
SATA drives are detected during BIOS detection. I hear the system
message "Now booting from operating system" at which point Windows
loads. Now, I hear a beep as the system reboots. I do not see the
Windows loader screen.

If I detach the SATA connectors from the drives, Windows boots -
reconnect, symptoms above return.

I also know the SATA HDD & controller works as I connected the SATA
data connector once Windows loaded and Windows/Disk Manager detected
and formated the SATA drive.

BIOS boot order set to SCSI. All other boot options disabled.

Any ideas or is this boot order a "feature" of this motherboard?

It's a feature of ALL motherboards that the boot order for SCSI devices
(indeed the enumeration order) depends on where they show up on the PCI
bus - typically things nearest the PSU end get selected for booting
first. Sadly I bet the on-board SATA controllers come out ahead of even
the first PCI slot (SATA is pseudo SCSI). You may be able to figure it
out with MSInfo32 or with AIDA32 or whatever.

I'm not sure whether marking the SATA drive partitions as not-active, or
not-bootable, or whatever is going to make the problem go away, but I
bet that's the problem. Now if you attached the SATA drives to a
separate PCI SATA controller and put it further away from the PSU than
the SCSI card ... elsewise I guess you need to reinstall the/an OS to
the SATA drives.
