SYMPTOMS
========

After installing Microsoft MS-DOS version 5.0, Sperry XT computers will not
start from the hard disk, will not start from the Uninstall disk, and if started
under a previous DOS version, a DIR command will display only random ASCII
characters on the hard disk.

WORKAROUND
==========

Upgrading the ROM BIOS to version 1.58 may correct this problem.

MORE INFORMATION

  T3070-00, then ROM feature type (part no.) is F5083-00.
  T3070-02, then ROM feature type (part no.) is F5083-01.
