SYMPTOMS
========
EMM386.EXE version 4.48 does not enable HIGHSCAN for some AMI BIOS.
CAUSE
=====
EMM386.EXE checks the AMI BIOS date and does not enable HIGHSCAN if the BIOS
date is one of the following:
04/25/91
05/05/91
07/07/91
06/01/92
These AMI BIOS chip sets use the F000h-F7FFh upper memory area (UMA) range and
are therefore incompatible with HIGHSCAN.
