Hi all,
  
  We have a Gigabyte GA-7DPXDW motherboard with the AMD 760MPX chipset
and the onboard Promise Fasttrack 100 IDE-RAID with Maxtor 160GB
drives.  When booting off the 4.6 iso image, the install will panic
during the boot process if the drives are left connected to the onboard
promise ATA 100 IDE-RAID.  If we disconnect all drives from the onboard
promise ATA 100 IDE RAID and only hook up a drive to the master IDE
controller on the motherboard, we can boot up and install 4.6.  Then,
when we reattach the 160 GB drives to the onboard promise ATA 100 IDE
RAID controller the system will crash during bootup after displaying
several messages similar to the following (there is one for each
drive):

ad0 maxtor 4G160J8 Read command Timeout tag=0 serv=0 - resetting trying
fallback to PIO mode
ata3: resetting devices

then a kernel panic will occur (on 4.5-RELEASE-p6 it would boot up but
these drives would be stuck in PIO mode and therefore be terribly
slow).

As indicated in the 4.6 release notes, we tried setting hw.ata.tags="1"
in /boot/loader.conf to no avail.

Unfortunately this setup is working fine under Linux meaning my boss
wants me to switch.  I'm desperate to try anything to get this to work
with FreeBSD since I can't stand linux.

From some searches, it seems the onboard Promise ATA 100 IDE-RAID may
not be supported under FreeBSD?  Can anyone confirm/deny this?  I don't
need the RAID functionality to work but I do need all the disks to
function properly as independent disks (tried turning off the RAID in
the BIOS but it didn't help).  Any thoughts?

  thanks.

  Orrie
