Hi,
Thanks for the reply. However, the netbook in question does have more than 512MB of RAM. According to the BIOS it has 1014MB Extended memory and 640KB System Memory. Also, this error is encountered when we are trying to PXE boot using DOS (that is the only method we use). Here is the exact sequence I see during boot with the troubling parts bolded:
Downloading DOS Boot Diskette Image
Transferring control to DOS Boot Diskette Image
Starting Windows 98
Windows XMS Driver Version 3.95
Extended Memory Specification (XMS) Version 3.0
Copyright 1988-1995 Microsoft Corp
Error: Unable to control A20 Line!
XMS Driver not installed
Warning the high memory area (HMA) is not available!
Additional low memory (below 640K) will be used instead
After this it simply hangs at the Bootworks(tm) Version 6.9 (9020) screen.
Any thoughts?
