I remember trying the card in an HP Pavilion. Instead of initializing
the RAID BIOS, it gave an error. However, in Windows, the two extra IDE
channels were installed and the drives showed up just fine. Anyway,
I'll give it a shot.

I agree, BIOSes are pretty stupid. I'm a PC user most of the time (but
I just bought a beautiful Lombard to take to school as my primary
computer, which will have OS X/Gentoo). All BIOSes do is just slow down
your boot-up time. First, the graphics card's BIOS loads, then your
system BIOS loads and does all the boot-up tests, then your network
card's BIOS loads, then your RAID controller's BIOS... oh god, that's
the worst BIOS of all. It takes like 30 seconds just to reach the
bootloader, and that's with all the quick boot options turned on. I
just wish BIOSes followed some kind of standard so I could LinuxBIOS
every PC I use.
