To boot from ra(1,0) by default (or by B RAS/B RAM from the 780
console), you have to hack up the boot program (/sys/stand/boot.c, BOOT
on the floppy) a bit. What we did was use r9 to specify the device and
partition (though using the high word of r10 might be better, since
it's already set to 0). Basically it's a matter of replacing the
string at the top with the right numbers (it already replaces the "xx"
based on r10, a.k.a. devtype).
Then all you need to do is edit RASBOO.CMD, RAMBOO.CMD, and DEFBOO.CMD,
to include the device and partition information.
