The utility file SRXTEST.COM that accompanies this README.TXT file and an AUTOEXEC.BAT file is provided for testing your pc to see if it uses an SX processor chip and if so, if the processor in your pc can use an upgrade processor whose availability is yet to be announced, but whose target date is the later part of the fourth quarter 93. The attached file SRXTEST.COM is a program which will tell you whether or not a 386SX can but upgraded. To use this program it must be run under a "clean" DOS environment. Thus I recommend that you get one 3.5" and one 5.25" floppy and format them as bootable disks to guarantee a "clean" DOS environment. See instructions below: 1. Format floppy disks by typing FORMAT A: /S Note: For low density disks use the following Format command 3.5" disk: FORMAT A: /S /F:720 5.25" disk: FORMAT A: /S /F:360 2. Copy the autoexec.bat file accopanying these files to your bootable floppy COPY AUTOEXEC.BAT A:\ 3. Copy SRXTEST.COM to the floppy disk COPY SRXTEST.COM A:\ 4. Put the floppy into Drive A: on any system and reboot From DOS: From Windows: the From OS/2: Press right mouse button Select Shutdown If you have a questions please call. 1-800-848-2979.
