Has anyone tried booting this as a USB yet?
For some reason, I am completely unable to boot it.
I have been trying various open firmware commands, but it simply cannot
boot.
I downloaded the Alpha the other day, with no success on booting.
I zsynced it today and MD5SUM'd it.

So... here is the problem

boot usb1/@1:2, \\yaboot
wont work...
I get this helpful? message


MAC-PARTS: LOAD <noninterposed> not supportedload-size=0 adler32=1
LOAD-SIZE is too small
ok

I tried usb2 and usb3 on two machines and then I boot to yaboot, on the HD.
Anyone have any thoughts about what is going on?  Any OF commands I
could run to find out more info here?
