OK, but SAS (Serial attached SCSI) is technology in the area of storage
interface technology where all big storage vendors see future (e.g. they
give up: FC and SATA drives, SATA drives are replaced by MDL SATA drives
(SATA 7200RPM drives with SAS interface)).
The problem isn't scsi. The problem is the lsi adapter. Problem #1 is
the hardware design which makes it hard to emulate it correctly and #2
that you need a non-redistributable rom file to boot from it.
#2 isn't an issue actually, at least for Debian users --
I just patched extbook back to allow booting from scsi and
to let people some transition time to move from boot=on
syntax which was supported before 1.0 and dropped suddenly
without any warnings in 1.0, breaking people setup. I
think I'll continue shipping extboot support at least as
long as there's no native support for scsi booting in bios.
