This is my area for Sun related stuff - primarily for my Sun SPARC-II Ultra 80 wooo hooo
quick notes:
For PC Keyboard with adapter box:
Break+A - gets you into the OBP boot area
For Sun Keyboard
Stop+A (standard)
Stop+N (resets OBP settings?)
To connect from linux to a sun serial console:
# screen /dev/ttyUSB0 9600
where /dev/ttyUSB0 is the serial port on your linux box that you are connecting from
My OS choices seem to be:
*BSD
FreeBSD - boot with “boot disk0:f”
FreeBSD SPARC Install manual
Ubuntu
Aurora
Fedora (doesn't seem to have sparc support anymore)
OpenSolaris
