Re: [parisc-linux] SCSI driver for E-class servers - SPIFI ?

Thanks, for the answers.

I never thought, the SE stands here for the single ended, I know the 
difference between SE and differential.

BTW: It's me, who wrote the MUX console support, and this is already
checked in into the Linux tree (for half an year now). 
But I am interested in having a full device support....
