Re: Booting An Ultra Sparc 10

Stephan,

You can make the Open Boot Prom skip the on-board graphics controller by 
doing the following:

At the ok prompt type the following:

1) ok " setenv pcib-probe-list 1,3 "

       {This will mask out device "2"(m64b@2)on motherboard, and
        force the system to use the PCI graphics card instead.}
        
2) ok " reset "    

        {This will store new entry into the nvram, so the PCI card 
        is the console boot device.}

That should work - we do that in our lab to test other graphics cards.
