you'll need a sparc bootable cdrom (512K blocks, vs 2048), and media cds.

hit stop-A (send a break signal if on the serial console) to get the OK

boot cdrom -s

that *should* boot the kernel in single user mode, bypassing the root
password that's stored in the prom.

the other method that may work is pulling the NVRAM chip, and booting
without it. the problem with doing this is that the machine will forget
who the hell it is, and it won't clear the prom passwd.

see above.
