               AST PREMIUM/386 TOWER EISA DETECTING RAM MEMORY AT 512K

    PROBLEM:       When the system is configured with 512K of base memory the
                   system BIOS may incorrectly identify LAN cards RAM memory as
                   system memory.  This problem will occur when the LAN card RAM
                   has a starting address of 512K.

                   When the system is re-booted via CNTL-ALT-DEL the following
                   error message is displayed:

                   [20.30] Memory size error - Run EISA config utility.

    AFFECTED
    SYSTEMS:       Premium/386 Tower EISA system board with the following part
                   number:

    CAUSE:         System BIOS incorrectly testing memory in the
                   512K - 640K range.

    SOLUTION:      This problem has been resolved with a new release of the
                   system BIOS.  Customers experiencing this problem should have
