Method to Provide Fixes for Diagnostic Programs on CD-ROM and Tape
Media

      Disclosed is a method for releasing fixes on diskettes for
diagnostic CD-ROM disks and tapes.

      Diagnostics for RISC System 6000* are released on tape and
CD-ROM.  When using the diagnostic tape or CD-ROM disk to boot a RISC
System 6000, a set of tests are run against graphics adapters,
keyboard and serial I/O ports, before attempting to use the system
console.  If a problem is detected during these tests, the system
will halt with a series of flashing seven-segment Light Emitting
Diodes (LEDs) to report the failure.  Situations will arise when
problems in the diagnostic software or hardware changes will prevent
the system from coming up.  These problems may be fixed by modifying
the diagnostic programs or microcode.  To prevent having to release
new CD-ROMs or tapes, a procedure for using a fix diskette is
defined.

      The diagnostic fix diskette will contain a .signature file
identifying it as a diskette containing diagnostic fixes.  When
bringing up a RISC System 6000 from CD-ROM or tape diagnostics, boot
code on the CD-ROM or tape will attempt to read a diskette.  If a
valid fix diskette is detected, its contents will be read in and a
pre-defined shell script, '/etc/diagpatch' if present will be
invoked.  This script, which is optional on the diskette, will ensure
that the fixes on the diskette are properly applied.  If the file
'/etc/diagpatch' is not present, th...
