[comp.sys.mac] Hyperdrive 20 and System 4.1

berger@datacube.UUCP (05/25/87)

Has anyone who has  a hyperdrive  20 internal  disk, tried installing
Mac System 4.1?  I just recieved Mac System tools  2.0 which includes
system 4.1 and Finder 5.5.  If I install it in  my hyperdrive startup
drawer  or  I  build  a  floppy  with  System  4.1  that  has had the
Hyperinstall process done, I can not open  the starup  drawer or boot
from the hard disk.  System 4.0 works fine by the way...

I'm running an updated Mac+ and had my  hyperdrive controller updated
about a month ago when I had my Mac 512 updated to a Mac+.

General Computer (through my dealer) advised me not to run 4.1/5.5 on 
my Hyperdrive 10 until they release V3R2 of the Hyper system software,
in "June or July".
