Manuel,

I just did the following on the Beige G3 at work:
  1. Terminated the SCSI chain with a 25 pin terminator plug.
  2. Used Suntar to write boot.fs to the scsi zip drive
  3. Set load-base and real-base
  4. Did a boot scsi/sd@5:0 -a   It failed.
  5. Did it a second time(no reset or anything), it succeeded

The moral of the story is that the partition 0 bootloader can run in places
where the firmware is known to be problematic, like a Beige G3.

I haven't gotten to the IDE CDROM this time, but I did hook up my rom
burner (a SCSI device) to use as a CDROM reader, and the partition 0
bootloader would read NETBSD.RAM off it.

I haven't gone any further because I don't have disk space prepared to
install netbsd.

I tried this yesterday without the terminator plug and it definitely failed.
