Unfortunately, this driver is not available to be loaded as a module either. the GENERIC kernel comes with the needed driver (called bt). You don't have to compile a new kernel, but you are going to have to replace the kernel on the disks with one containing the needed driver (like GENERIC). Either way, the recovery procedure involves booting off a CD and replacing the on disk kernel. -- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB signature.asc Description: This is a digitally signed message part.
