It seems that to get this card to work as a plain non-RAID
controller under Centos 5.5, one has to do an overwrite of
the PCI controller card's BIOS.
It either works in RAID mode, or ATAPI controller mode as a
mass storage controller. There one BIOS upgrade for
programming it as a RAID controller, and another BIOS
upgrade to program the PCI card as an ordinary IDE
controller.
Well I have flashed the BIOS on the ITE8212F PCI controller
card with the ATAPI upgrade, and now it appears to the
Centos 5.5 kernel as a plain PCI IDE controller - 100%
native.
This is just what I needed, as I would like to move all disk
I/O intensive stuff onto a small 40GB drive on this
controller. So the kernel needs to see this drive at boot
time, before the kernel has a chance to load any dynamic
drivers.
Kind Regards and a very Happy Christmas to all,
