preservation: linux and ST506/412 - SCSI bridge boards

[Jules Richardson]

Out of interest, has anyone else ever managed to persuade linux to talk to any 
of the Xebec/Omti/Emulex/Adaptec ST506-SCSI bridge boards? Most of the boards 
are SASI, or at best semi-SCSI, so Linux refuses to talk to them.

Just wondered if anyone on here had hacked any of the kernel drivers so that 
they'll work. As I understand it, the main problem's that the kernel drivers 
issue a SCSI identify command at boot time - which of course doesn't exist on 
any of these boards, and from that point on the kernel refuses to acknowledge 
that there's even a board there.

I *think* a SASI board should work with a SCSI HBA, providing there's nothing 
else on the SCSI bus (at least that's what the Omti manuals suggest).

Sure would be useful for backup purpose, but last time I looked at the kernel 
SCSI code (for an adaptec driver in that case) it was pure spaghetti :-(

cheers
