Yes, contingent on you choosing the right controllers and/or making
the appropriate hardware modifications and applying the second controller
patches.

You must be able to jumper one controller at both a secondary address
AND interrupt - many disk controllers can do the former, but not
the later, in which case you have to perform surgery with an Exacto
knife and conductive pen.

>Can Linux use both, the st-506 and the ide, at the same time?

Yes.

>(one as hda and the other as hdb).

If you've got it set up the "official" way, one would be hda, the other
hd1a.

- If you have BIOS support for both controllers.

- If you put boot images on a small partition (ie, a "mini-root")
  on the first disk (BIOS supported) and mount the rest of Linux from
  the other.
