Kent Sandvik,

Many thanks for your reply.

The default SCSI device driver supplied with A/UX 2.0 works OK with A/UX
file system CD-ROMs. The problem seems to be when I install the Mac OS Apple
CD-ROM driver in the system folder in the Mac partition on the startup
volume to read Mac HFS CD-ROMs. The B-3.0.2 installer complains and you have
to install the resources one by onw.

The release notes state that you have to turn on the CD-ROM drive before you
startup. Then it says to insert the Mac HFS CD-ROM and login. However, if
you turn on the CD-ROM drive and startup A/UX without a CD-ROM inserted I
keep getting the erratic read/write errors with my hard disk. If you remove
the Mac OS Apple CD-ROM driver from the Mac OS system folder on the startup
volume, or startup A/UX with a Mac HFS CD-ROM inserted the problem seems to
totally disappear.

What limitations are there using Mac HFS CD-ROMs with A/UX. You can switch
the CD-ROM driver on at any time and use A/UX file system CD-ROMs, but the
only way around this problem I have found is to insert a CD-ROM when starting
up A/UX.

On a separate issue, regardless of whether the Mac OS Apple CD-ROM driver is
installed in the Mac OS system folder on the startup volume, I get the
following erratic problem ocassionally when I log in. An empty
debugger/dialog box appears which appears to be continously being redrawn.
You can apple-control-e and try and login again.

Any help with both problems would be greatly appreciated.
