Unfortunately I think the 'new' command at the 'ok' prompt is for newer
proms maybe? When I type 'new', it says "new ?". Maybe I have version 1
OpenBoot roms? Anyway, 'probe-scsi' works, but not 'probe-scsi-all'. All
it says about the new drive is "Target 4, Unit 0" (plus info on the
manufacturer, etc. The INSTALL document says:
If you have to use the old-style `sd(c,u,p)' syntax to boot from a
SCSI disk, you can calculate the parameters as follows:
`c' - specifies the controller number
`u' - the hexadecimal number obtained from evaluating
the expression `(8 * TARGET) + LUN'
`p' - the partition number from which to boot (0=`a', 1=`b',
etc).
but I don't know what goes in 'c', and 'u'. Is the controller number, c,
equal to 0 because probe-scsi said "Unit 0"?
In the line for 'u', is TARGET, then 4 in my case? What about LUN?
Sorry for so many should be simple questions...
Thanks
