My experiences from 3+ months of testing w/ M$ indicated BIOS conflicts when booting with RAID pci add-in cards installed & power applied to the HD(s) that were attached. If I booted w/o the pci RAID powered and then applied power from my 2nd Power supply after O/S started it always locked up. Many emails to mainboard tech support & pci card mfr (Including tech Department heads) have been unremarkable, Always got prompt replies, but no real solutions. May try some BIOS tweaks now that I know about them, but concerned of breaking BIOS completely!
Only way I could avoid all the BIOS conflicts was to DISABLE all RAID options (S&I) & both IDE channels, which I found unworkable as I lost use of 2 HD & 2 DVD burners.
Would have returned the cards, but were out of warranty period, ya want to try any of them?
Only <$100 PCI add-in that worked as I recall had 4 WD740GD attached (RAID 0, 1, or 0+1, all options worked booting O/S)
HW used for those tests; socket 939 nForce4 mainboards, tried Mandrake, oSuse 9.1Pro, RHEL3 & had same BIOS boot problems even though I never used the linux O/Ss. I have not tried my various PCI Add-in cards yet w/ any recent Linux distro, but FYI my 2 installed PCI Express x1 SATA 3.0 cards (w/o any HD attached yet!) are recognized by FC5, Slack 11, the sil-### drivers are loaded during recent installs on Tyan S2865.
BIOS on an IBM (PII-350) Aptiva would not recognize any of the SATA RAID PCI add-in cards I tried; IDE was OK, SATA 150=nada.
Chris, IMHO your BIOS on the older systems may not allow (aka SUPPORT) cheaper SATA RAID cards to operate, for O/S boot or storage! SATA 3.0 is probably completely out-of reach, btw SATAII is not=SATA3.0 Gbs as SATAII includes SATA 150Mbs!
Your best bet might be IDE RAID, which controllers are you considering (VIA ##, Sil##, etc)? Edit original thread, add reply, more HW specs
