I am having a problem with the Promise Fasttrak 378 SATA controller.
I'd like to dual-boot and use the system in RAID Mode. When I install
RHEL 4 WS update 3, the installer see BOTH drives even though the BIOS
has RAID mode selected and the Array had been created in the Fasttrak
utility.
I've tried installing on just one of the two drives (/dev/sda) and
also using sda and sdb in a md0 software RAID. Regardless, the
systems hangs on boot up right after the NASH entry. I suspect it
can't read the drive(s) becasue the linux fasttrak drivers have no
knowledge of the controller's onboard RAID settings.
Has anyone had luck with this configuration?

dmraid handles fakeraid setups such as this. Prior to FC5, dmraid was
not initialized in the boot process, so for example, I installed FC4 on
a fakeraid array the following way:
1. Install to an alternate non-fakeraid drive.
2. Boot Fedora or rescue mode and start dmraid, then create partitions
on fakeraid.
3. Move partition contents.
4. Patch mkinitrd and create a new initrd with it.
5. Edit grub.conf and fstab appropriately.
I wrote an FC4-specific version of the guide I used, RHEL4 should be
very similar:

FC5 has an installer that initialized dmraid and contains dmraid in
initrd, so those two main issues are gone, however the 2.6.16 kernel and
dmraid don't get along well yet :/.
