            These systems may fail a variety of Intel Diagnostic tests,
    
            including the Conformance test. AST offers a BIOS upgrade to solve
    
            this problem. BIOS v2.20 and later are known to fix this problem.
    
            Contact AST directly, or download PEBIOSSL.EXE from the "FILE",
    
            "SELECT LIBRARY", and then "SYSTEMS" section of the AST BBS at
    
            714-727-4723.

            These systems may fail the Environment  test of Intel's
    
            Diagnostics. This is due to a VLSI 82C320 Version A chip problem.
    
            Users with this problem should contact AST.

            Early versions of AT&T 6300 BIOS would not recognize a math
    
            coprocessor.  If your computer can't seem to be find the 8087, 
    
            contact AT&T technical support to find out how to get a newer
    
            BIOS.  (AT&T ph: 800-922-0354, or 800-543-9935)

       The jumper labeled "387" needs to be set, it is located in a row of
    
       jumpers along the left side of the motherboard. There is a diagram
    
       inside the system's cover.
