Greetings,
I am trying to get a kernel running on an Intel SCB2 board. It has
onboard Promise PDC20267 RAID and Serverworks IDE controllers. The
problem I am seeing is when Promise support is compiled into the kernel
the Serverworks IDE chip will appear but fail to become available. The
CDROM drive attached to the Serverworks chip is never visible. If I
disable the Promise chip in the board's bios and boot the same kernel
the serverworks IDE attaches and the CDROM shows up and can be accessed.
I have tried both 2.4.18 and 2.4.19 source and played with different
config combinations. Nothing I change appears to correct the problem.
I am pretty sure this is something I am doing and not a bug. If someone
would be kind enough to look at the dmesg and /proc/pci excerpts below
along with the kernel config options below I would be grateful.
Thank You,
Jeff
