Formatting hard-disks for A/UX 2.0

Sat May 26 00:22:54 AEST 1990

I heard a nasty rumor that A/UX 2.0 won't work unless the disk it's being
installed on is formatted using Apple HD Setup.... Is this true?

What disks does HD Setup recognize then?? I have a CMS Platinum 170 (which
is CDC-Imprimis based) sooooooo will I be able to format this using
HD Setup?

Are there any other disk-formatter software packages that could do the job?
(LaCie SilverLining, for example...)
