Hi Tony,

I had the same problem while installing FreeBsd 5.4 on an Ultra5. 
The problem is that the driver for the Openfirmware is not compiled into the standard kernel.
That means you do not get any output on your screen but your Freebsd still works.

I used the following workaround (You need an computer with a terminal-program. Connect this to the tty[ab] of the Ultra10):

- Restart the computer. 
  While memory initialization press Stop-A to get to the bootprom.
- do one of the following comands (depends on where you connected your sun):
  select io ttya  
  select io ttyb
- then enter: go

Now you should get the output to your terminal and you can go on installing FreeBSD.

After installing FreeBSD you should rebuild your kernel.

Use the following option to enable the openfirmware console again:

 device          ofw_console     # OpenBoot firmware console device
 I hope that works for your ultra10.
