Re: "rock solid" motherboard
I could only find one SATA disk in Linux and never see
the PATA whether RAID was turned on or off because of the
sata_promise driver for kernel 2.6.10. I could not write
to the RAID in Linux without errors. The new 2.6.11 kernel
is supposed to make the PATA visible under Linux. I haven't
tested that yet.
I believe that 2.6.11 doesn't yet include the change needed to support
PATA drives on the Promise controller. However, you only need to apply
Jeff Garzik's libata patch on top of 2.6.11 for this to work.
