Suggestion: A little more specificity might have helped people help
you. For example, you should have said "I want to buy an Intel model
D865PERL motherboard, which is based on the Springdale chipset and
includes an Intel ICH5 Serial ATA chip. Furthermore, I want to install
onto SATA hard drives, and would like to use RAID1 (mirroring)."
Now, some Springdale-based motherboards include some sort of RAID
functionality, but it's almost certainly some sort of proprietary
software RAID, and I doubt that Intel is cooperating with the open
source community on that. Even if they are, the history of proprietary
software RAID suggests that it will suck rocks, compared to Linux's
native software RAID ("md" driver).
So, let's set the RAID question aside and consider the ICH5 one. Fedora
Core 1 installs using a "kernel-2.4.22-1.2115.nptl" kernel -- Alan Cox's
2.4.22-ac1 with a number of 2.4.23pre patches. You _may_, if you're
reasonably lucky, find that your drives are stable using the 2.4.22
stock IDE driver. Or, the system may tend to freeze. If your
motherboard supports it (which some do, and some don't), then it'll help
immensely to put the BIOS's ATA ("IDE") functionality in "legacy ATA
mode" for the duration of installation. Then, you can compile and
install a 2.6.x kernel (which includes Jeff Garzik's libata driver set
for SATA chipsets), or your choice of 2.4.x source code with libata
applied as a patch. This will improve your ICH5 support quite a bit.
And, oh yes: You'll want to use Linux's own software RAID. ;->
