Looks like the new list works - congratulations on being the first to test
it out!!

I see from your other message you have figured out all the exciting stuff
happens on Serial 1.
At some stage you will need to replace the MK48T02. This can be a tricky
procedure. The area used for the Ethernet MAC address etc is write
protected by hardware by default. I have not found any way to overcome
this restriction so you will need to do a transplant in another machine.
The procedure for doing this on a sun can be found in the port-mips
archive:

I will transfer this to the FAQ section shortly. There is also some more
info I wish to add.

If don't know what the root password is, the following procedure boots
RISC/os into single user:
boot dksd()unix initarg=s
