Are we talking about an SGI here? I distinctly recollect it being a
PC he was using..
sorry, 'twas meant to be light-hearted. Should probably have worded
it as "you'll learn that isn't /always/ true"..
Obviously he wasn't talking about an SGI. SGI's don't support ISA/PCI
cards /you know/.
> SCAM doesn't any need OS support, it's taken care of by the adapter
Well, call me gullible for believing the documentation, but all my
SCSI device manuals say that, for instance, NT4 does not support SCAM,
whereas W98 does. Me, I'd conclude that some OSes support SCAM, and
OS doesn't need to support SCAM. it's just a sort of 'plug and
play' for scsi ID's. Once the ID is set via SCAM, who cares? indeed
you can set the ID on a SCSI device via SCAM then move that device to
an adapter that doesn't support SCAM and the device will keep it's
SCAM set ID. SCAM is a firmware thing, and the device should keep
it's ID in nvram.
(although if an OS adapter driver chose to support reprogrammin
device ID's via SCAM it could, but there's no need for this. hell
you could also do it with a userspace programme.)
just wanted to correct that little mistake in your otherwise
excellent and v helpful reply. Sorry if my terseness came across as
