I've got an  Alpha 3000-800 that I'm trying to install NetBSD on, and 
I've run into a problem...

The machine starts to boot from the 1.6_Stable install floppy, loads the 
first floppy, prompts for the second diskette, continues to load, the 
quits with the message:

?02 KSP INVAL
       PC = 00000000.000604E5     PSL = 00000000.00000007

I've also tried to use 1.5.3 install floppies, with the same result, 
just a different value for PC.....

The machine has 320 MBytes of ram, an internal RZ26, external RZ28 and 
floppy drive in a StorageWorks tower, and a PMAZC-AA with no devices 
connected. I thought it might be an issue with the PMAG frame buffer, 
but the behaviour is the same without it. I'm using a VT320 for a console.

Any ideas as to what the problem might be??

Thanks.......
