I bought an Adaptec SATA controller to add some backups to a system that
already had an Adaptec SCSI controller.* They're both recognized as AIC7xxx,
but the second one is somehow blocked.

I can access the on-controller configuration stuff during BIOS startup, and the

drives appear good.* I just cannot get things working with the Linux kernel.
I think this is the relevant part of dmesg output.* Notice the message about
"Unable to reserve mem region".* In case I'm wrong, I've attached the whole

thing too.
