This file outlines the installation of the STPC video drivers.

These drivers are designed for the STPC hardware under version
1.12 of Photon.

The following four files are required for the STPC drivers.
Confirm the sizes for each of the files:

Pg.STPC		129682
Pg.STPCdc		123896
STPCbios.trap	76063
crttrap.list	271

Copy the files to a dos formated floppy, then place the floppy in the 
board floppy drive 

To start type the following QNX command:
# sin ver 

This will tell you if Fsys.floppy and Dosfsys is running, if not type 
these QNX commands:
# Fsys.floppy &
# Dosfsys &

Now your dos floppy is  mounted as /dos/a 

Back-up any existing files that would be over-written by these
new files.  

example :
# cp /usr/photon/bin/crt/crttrap.list /usr/photon/bin/crt/crttrap.list.org


To copy from the dos floppy use the command:
# cp /dos/a/
& copy the files to the following directories

*IMPORTANT*: Copying the files to a DOS floppy changes the 
filenames so you must ensure the files are copied to the exact 
filenames below including case.  

/usr/photon/bin/Pg.STPC
/usr/photon/bin/Pg.STPCdc
/usr/photon/bin/crt/STPCbios.trap
/usr/photon/bin/crt/crttrap.list

*IMPORTANT*:Check the file permission and ownership.
When transferring the files to QNX from a Windows system, 
the permssions are typically changed. 

Use the following command to change permissions to 
match below:

#chmod 777 <filename>

-rwsrwxr-x  root  root  Pg.STPC
-rwsrwxr-x  root  root  Pg.STPCdc
-rwsrwxr-x  root  root  STPCbios.trap 
-rw-rw-r--  root  root  crttrap.list

You should now be able to change directories to the root ('/') of your
filesystem and run the following two commands from the command line:

# crttrap clear
# crttrap trap

NOTE: crttrap is a QNX utility used to detect the video driver.

You should now be able to run Photon using the STPC drivers. 

From within the Photon Desktop, select the right button. A pop
up menu will appear and you can select Configure Display. Change 
the resolution and photon will load the STPC graphics drivers.
The next time you enter Configure Display, the ST Microelectronics
driver will be listed.
