Windows NT + Award BIOS Memory Hole
Posted on 1997-02-07
We've got a Windows NT machine (Pentium 100) with 32M of memory. We'd like to take advantage of an Award BIOS (version 4.50g) feature that defines a 1M "hole" in memory at 15M. This hole does not map addresses to system memory, so that it is ideal for positioning ISA bus devices that use memory mapped I/O. Our problem is that when we enable this BIOS feature, Windows NT boots up reporting only 15M of memory. For some reason, it can't see the other 16M of memory on the other side of the hole. How can we fix this so that all the usable memory is available?
