sorry about the confusion, it's not running 4.1.2, but is running SunOS
release 5.6. I get a reasonably readable screen if press PAUSE A to get to
the OBP. How do I change the display configuration ? The display scrambles
on the least hard disk activity.

Booting into single user mode is asking for a root password to go into
single user mode.

I don't have a CDROM drive with the sparcbook and I don't have access to
other SPARC systems. Is it possible to boot off a NetBSD floppy and mount
the partitions ?

Thanks,
