Installation on a DS20

[Bernhard Gschaider <Bernhard Gschaider unileoben ac at>]

I tried to install RH 6.0 on a DS20 the way it is described in
http://www.digital.com/alphaserver/linux/install_guid.html

Everything works fine up to the point when the ramdisk-disk
has been inserted and uncompressed: I am thrown back to the SRM
console and I am told that the processor halted

I have already tried a number of fixes:

1. Somewhere in this list it was written, that with some Versions of
   SRM os_type should be set to vms. Tried that.
2. Got the newest ramdisk.img from redhat.com. Didn't help.

The Hardware in the DS20 (as reported by AlphaBIOS) is
DIGITAL PBXGB             - VGA (PowerStorm 3D10)
two NCRC875               - SCSI
Digital 21140             - Ethernet

Could anyone tell me if the hardware is the problem (all the components 
were installed by Compaq so I naively thought that they can't be a
problem)?

Or is there something that isn't mentioned in the Installation Guide?

Please help me, I don't want to be stuck with just Windows NT on that machine.
