Hi,

I commited some fixes to boot from an ide slave drive and to boot from the
secondary ide channel.

Havard Eidnes and I tested it on two eb164 systems.

The dec_550.c (miata) and dec_6600.c (ev6) are based on the dec_eb164.c
so it should also fix problems to autoboot from ide drives.

syssrc/sys/arch/alpha/alpha/dec_550.c revision: 1.6
syssrc/sys/arch/alpha/alpha/dec_6600.c revision: 1.3

Btw, there are a few '/* XXX function? */' in dec_550.c and dec_eb164.c.
Should that be changed like it was in rev 1.30 of dec_eb164.c?
