Generally what I have seen is that real hardware raid solutions are
not just x86 only, and they work under LinuxBIOS. Because they do
not need the x86 BIOS.
For IDE raid I have not heard that those are actually real hardware raid.
For an onboard controller even an ADLO type solution will be insufficient
because installing LinuxBIOS will kill the option Rom.
Basically it is a matter of getting it to work under Linux without
needing an option Rom. And for scsi that has not been a problem.
