OK.

I have a DS20 here and a RedHat-6.0 (Hedwig - Alpha) CD here.
In the document "Red Hat Linux 6.0 - Alpha installation Addendum"
(doc/alpha/booklet/doc001.htm) which came in the CD, it talks about
Alpha
BIOS boot-up only through MILO.
My questions are : Can Alpha BIOS boot happen only through MILO?
Is there a MILO for DS20?

I could not find any links to specs or docs in http://www.compaq.com.
Any idea where to get specs from?
