Re: Asus K7V motherboard and Promise RAID bios patch on Linux?

I'm thinking of patching my Asus K7V motherboard (which has a promise ATA-100
controller onboard) with a modified Promise BIOS that allows it to become a
RAID controller. This can also be done by grounding one of the chip's pins,
whereupon the BIOS will recognise the controller as RAID and use it
accordingly, but the modified BIOS doesn't bother with the check, and just
works without hardware modification.
So what I'm wondering is: if I modify the BIOS so it thinks it's a RAID chip,
will Linux recognise it as RAID, or does it bypass the Promise BIOS anyway?
The "RAID" chip on most motherboards, including the K7V, is really done
by a software driver. You can do software RAID in linux from any IDE
channels, making the "RAID" chip uselesss. However, some of the RAID
motherboards have extra IDE channels. This IS useful, as you can add
more disks to your array.
