EP-4PEA+ SATA RAID 0 and Highpoint RAID

Does anyone know if it's possible to have BOTH the SiliconImage AND
Highpoint enabled, with drives on each, but boot to the SATA drives ?

I've currently got two 74 GB Western Digital Raptor SATA drives in RAID 0 on
the SiliconImage RAID, with Windows XP installed and working fine. The
Highpoint one was enabled but no drives were connected. Then I connected 3
of my old drives (2 x 45 GB and a 60 GB) to the Highpoint IDE sockets and
booted, but it wouldn't boot to the SATA drives. It appears to try to boot
to one of the drives on the Highpoint controller instead. If I do CTRL-H to
go into the Highpoint BIOS, it shows one of the drives as being the BOOT
disk. If I change it so none are the boot disk and reboot, it just does the
same thing and the first of the 3 disks on the Highpoint controller shows up
again as being a boot disk. It's as if it's not correctly saving the
change.

I had a look in the motherboard BIOS, but there's no option to boot from
SATA, just SCSI and the other usual ones (CDROM, floppy, etc). It looks
like the Highpoint controller is getting higher precedence over the
SiliconImage SATA one - which is the opposite of what I want.

When I initially set up the system and installed Windows XP, it asked for a
RAID controller disk and I just used the SiliconImage one - since I wasn't
installing any drives on the Highpoint one at that stage. But surely that
shouldn't matter if I'm just trying to boot from the SATA one ?

Any ideas anyone ?

I read an interesting article in a magazine the other day about motherboard
RAID and XP software RAID. They called motherboard RAID FakeRaid as the
processing is done by your CPU via the device driver while REAL RAID is a
self contained box with a special hardware controller. Sooooo the conclusion
was you might as well use XP software RAID with the added advantage being
that your disks are no longer tied to a specific raid
controller/motherboard. It would actually be possible to lift the disks out
put them in another box and windows would boot. Not possible with
motherboard RAID
