Patch Name:  PHSS_2084

Patch Description:  TVRX Texture Mapping + Zbuffering Microcode Fix

  TVRX with hidden surface zbuffering ON and texture mapping ON:  when
  drawing lots of polygons repeatedly in which a significant number of these
  polygons are very small (eg.  one or two pixels high) and are also texture
  mapped, there can be a problem where pixels do not get zbuffered properly.
  This results in speckling of pixels which should be hidden but aren't.
  Another result can be that everyother scanline gets painted with the
  background fill color, but no polygon pixels are allowed into those
  scanlines (looks like the picture has been washed out with background
  color).

After getting the patch onto your machine, unshar the patch (sh PHSS_2084).

To install this patch do the following:
1) Run /etc/update (Note: you must be logged in as root to update
   a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return" or
   "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source: /dev/rmt/0m" to "Source: /tmp/PHSS_2084.updt"
   (this assumes that you are in the /tmp directory where PHSS_2084.updt
   has been placed).  Note: You must enter the complete path name.
5) Press "Done".

The customize script that update runs will move the original software to

order to recover from any potential problems.  It is also recommended that
you move the PHSS_2084.text file to /system/PHSS_2084/ to be retained for
future reference.

If you wish to put this patch on a magnetic tape and update from the tape
drive, dd a copy of the patch to the tape drive.  As an example, the
following will create a copy of the patch the update can read:
dd if=PHSS_2084.updt of=/dev/rmt/0m bs=2048
