0x38 is 0x30 + 0x08 ..

My underscores were only an attempt to highlight the "0x" - some textmode
clients will render that as bold or underline, and for those that don't
it's still a reasonable visual approximation of an underline :)

I've got a list somewhere which I managed to find to help with mine - the
information is actually in one of the header files for a *BSD kernel :)

If you've got an older rev prom, you can type 'h' for help. If not, let me
know & i'll dig out a list of prom commands from here.. i /always/ have to
look these up too ;)
