[PATCH] pata_atiixp: Switch to cable_detect method (with correct patch)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Lets try attaching the right patch file this time

Not clear we should keep this ugly BIOS mode hack, but for now it can
stay. Possibly an ACPI based solution will work, or just doing drive side
detection now that is hopefully fixed.
