Hi all. I just installed rh4.1 on a seagate ultrawide drive, and wondered
why it says its refusing wide negotiation, and using 8 bit transfers.
Can someone give me some hints on how to get this working, and any
kernel-related parameters that I can change in the source? Should I be
enabling SCB and paging?
