If you are using the Promise controller that allows you to set up "RAID"
in the BIOS, I've enclosed my fstab and lilo.conf. You should build
pdcraid.o into your kernel, not as a module. Also, enable the FastTrak
feature. This card is also known as the Fastrak, and there are howtos
published for Debian. There is also some info in the Gentoo documentation.
In either case, if your drives are listed as hde and hdg, make sure
"boot off-board chipsets first support" is turned OFF.
If you don't have the FastTrak option, you should use the regular
software raidtools to create your RAID array. Then you need
to turn the FasTrak feature off in the kernel. I've never done this--
you may have to disable the BIOS of the IDE controller. If you do this,
you need to turn the "special UDMA feature" for the Promise controller
on in the kernel.
And if all this sounds like too much of a pain, you can, as Joseph
suggests, lay out the bread for a real IDE-RAID card. I personally like
the 3ware cards real well, but they are expensive.
Hope this helps,
