SparcStation 20 refuses to boot solaris
Hi
I got a SparcStation 20 with dual cpu. It has a disk with solaris 5.7 on it, but I don't know the root password so I decided to install a newer version of solaris or bsd.
When I load a CD, and run boot cdrom from OBP, it tries to find the CD drive as sd@6 while the drive is at sd@2. Booting with boot disk2:0 makes it run, but then I get an error:
The file just loaded does not appear to be executable.
I've tried with NetBSD, Solaris 9, Solaris 10 and got the same error. I've double checked that I have NetBSD for sparc32.
Any ideas?

first, have you tried holding down Stop+N keys while it posts? this will bring the SS20 back to defaults...
As far as I can remember, the SS20 is not supported by Solaris 10.
try the key combination and see what happens...
it has been a few years since I have played with this particular beast!
good luck and let us know how it goes!!!!

Didn't help. Same error again and it still tries to find the cd drive at sd@6.
Could it be because of my cd drive? I don't have an original sun one so I used an ancient CD-Caddy one (the only one I had). I set the jumpers according to the sparcstation manual.
I did some testing and it seems like debian linux actually boots. No other distribution or os does.
And I did notice that solaris 10 does not run on sparc32, but solaris 9 does according to the hardware requirements page for it.

Hello Anton,
at the ok-prompt use the command probe-scsi, this displays all detected SCSI devices.
Use devalias to display the current setting of the cdrom alias which expects to "see"
the CD-ROM at SCSI-ID 6 (this is the default).
This is an excerpt from the devalias display
cdrom /iommu/sbus/espdma@f,400000/esp@f,800000/sd@6,0:d
Without re-jumpering you can try to boot with the current setting
boot /iommu/sbus/espdma@f,400000/esp@f,800000/sd@2,0:d
If it succeeds I would strongly recommend that you re-jumper the CD-ROM to ID 6.
If you didn't like to re-jumper the drive or just missing the (additional) jumper, use the command
nvalias cdrom/iommu/sbus/espdma@f,400000/esp@f,800000/sd@2,0:d
to change to devalias for SCSI ID 2.
The internal harddisks are fixed to SCSI 1 and SCSI ID 3.
