Can't Recognize Beyond 64MB RAM on ALR Evolution Pentium

 Last reviewed: November 5, 1997
Article ID: Q123368

The information in this article applies to:
  • Microsoft Windows NT operating system version 3.1
  • Microsoft Windows NT Advanced Server version 3.1
  • Microsoft Windows NT Workstation versions 3.5, 3.51, and 4.0
  • Microsoft Windows NT Server versions 3.5, 3.51, and 4.0

SYMPTOMS

Windows NT is only able to recognize and use the first 64MB of RAM on ALR Pentium Evolution V-Q/60 and Evolution V-Q/66 computers.

CAUSE

These ALR Pentium computers have a Phoenix BIOS revision of 1.00.26b. ALR confirms that programs attempting to access the BIOS through INT15 calls are able to access only up to 64MB of RAM. The ALR Pentium Evolution series computers are shipped with 256MB of RAM.

RESOLUTION

In order to correct this problem, upgrade the Phoenix BIOS to revision 1.00.35b. Contact ALR Technical Support at (714) 581-6770 or (800) 257-1230 for more information.
