Greetings Roger,
I recently installed Etch on a U5 with an internal SCSI drive and a PCI
SCSI controller that is supported for booting via openprom. I removed
the IDE hard drive, and used a businesscard ISO via the IDE CDROM (on
its own cable) to boot the machine and start an Etch install.

Same as on an IDE drive on this platform. On Sparcs and Ultras, I use a
small first partition as /boot, and the rest of the drive as / and swap,
to live within the usual SILO partition location constraints.

After the base installation completes and attempts to reboot --- dumped
into openprom, as expected. There was no alias for the path through my
SCSI controller to the drive. I puzzled out a path, saved it as
"diska" (probably with nvalias), then set the boot device to "diska".

I probably used whatever the Etch installer set up. May have had to add
an initrd statement.
Using a 2.4.27 kernel.
