This beta, version TIG97161, is a pre-release version of 7043-140

Updating the firmware
---------------------

Follow the steps below carefully.  If something does not appear to
work, stop and get help.  Consult the system publications first.

1) Copy the firmware image, tig97161.img, to a DOS (FAT) formatted
   diskette.  (Under AIX, use "doswrite" or equivalent).

2) Go to the open firmware "ok" prompt --
  a) From a graphics display, press F8 when the icons appear during IPL.
  b) From an ASCII terminal, press 8 when the text "icons" appear during
     IPL.

3) Insert the diskette with the firmware image and soft-load it using
   the following commands:

        > setenv load-base 600000
        > boot floppy:1,\tig97161.img

4) A console selection may be run at this time to allow you to
   choose a display.  A graphics display is preferred.

5) Go to the SMS menu --
  a) From a graphics display, press F1 when the icons appear during IPL.
  b) From an ASCII terminal, press 1 when the text "icons" appear during
     IPL.

6) If the firmware icons or text appear and everything looks right,
   you can now permanently flash the new firmware image.

7) From a graphics display, use the firmware update utility.  Select
   Utilities from the menu, then Update and follow the on-screen
   instructions to complete the update procedure.

8) From an ASCII terminal, use the firmware update utility.  Select
   "Utilities" from the main menu, then "Update system firmware" and
   follow the on-screen instructions to complete the procedure.
