  My system is as follows;

  040 Cube
  16 Megs mem
  NeXT CDROM drive
  OD
  FUJITSU M2266S 1.2 gig HD

  My problem is this,  every time I attempt to copy something off of a CDROM
the system panics.  This also happens if I try to read a file from the CDROM,
as oposed to moving it to the HD then reading it.
  The CD's I have been using are both ISO-9660 format, one from Sun and the
other is the source code CDROM from Walnut Creek CDROM.
  And now, a few examples from the message file ;

  Any insight would be quite helpfull.

  Thanks,

  P.S. I was running Mamakos' slip, but the problem occurs even if the sysem is
not booted up with slip.  That is the only real tweaking I have done on the
system.  I dont have my 3.0 CDROM handy, so I don't know if the same problem
will occur with that CDROM.
