Read the NetBSD diskless (netbooting) how-to:
Once you get your boot server set up, you need to stop the booting of
your sparc5 by hitting L1-A or STOP-A, depending on which keyboard you
have. You'll be dropped to a prompt that should look like:
From the PROM prompt, type 'boot net' and hit return.
One thing you might try is 'boot -s' to boot the installed OS into
single user mode, the previous owner of the system might have set the
box to not require a root password to enter single user.
If that fails, do the net boot, figure out which disk is the OS disk and
has the root filesystem on it. Mount it, edit /etc/shadow, null out the
passwd field for root, save it off, unmount, reboot.
To set it to not need the root passwd when coming into single-user mode,
create the file /etc/default/sulogin with a single line: PASSREQ=NO
Once you've played around with Solaris for a while, install NetBSD and
join us here in this nice little community. =)
