Seems that bf24 cannot pick it autmatically (while Gentoo's kernel on the
install cd picked it up with no problems). Here's what you should do:
In a terminal window (alt+f2 or alt+f3 can't remember) run:
cat /proc/pci
and look for the info about the PDC controller. As part of the info you'll see
5 hex numbers listed one after the other, let's name the (a)-(e)
Write down the numbers, reboot the install cd again and at the boot prompt
write:
bf24 ide2=0x(a),0x(b+2) ide3=0x(c),0x(d+2)
b+2 means the value of b incremented by 2, and same applies to d+2.
Now the controller and raid should be detected.
This is from memory, so tell me how it goes

I was very disappointed by it. While working I pulled the plug on one of the
hd's (RAID1 config) to simulate a dying HD, lot of timeout message started
appearing and the systems froze. Once restarted the system didn't boot.
I bought a real IDE Raid soultion (LSI Logic), and it is awesome (although a
bit expansive). It handled to dying hd trick with no problems, after a short
pause the system continued working normally. When re-connected the power it
started rebuilding the array automatically, I was very pleased by it.
