		      Premmia GX P/100 Matrox BIOS and SW1

This is an informational bulletin.

The Matrox User's Manual erroneously states that leaving SW1 in the ON 
position is not safe.  SW1 (the BIOS protect switch) must remain in the ON 
(flashable) position on the Premmia P/100 systems.  The BIOS can not be 
updated if it is in the protected state when the switch is in the OFF position.

For additional information on this issue, see Technical Bulletin # 1379.
For additional information on the Matrox BIOS 1.8 (AST part number 
905572-031) or higher, see Software Bulletin # 0258.  

Both of these bulletins are downloadable from AST's BBS (817) 230-6850.
