When my system, a 386sx with NEAT motherboard, boots up I get the following
message from HIMEM.SYS:
Installed A20 handler number 1.
WARNING: Can't disable A20
64K High Memory Area is available.
This occurs even if HIMEM is the only thing in the CONFIG.SYS file,
so it should not be a conflict with another memory manager.
I'm new to Intel/IBM architecture and don't really understand what
this message means or what its implications are; other than that
the A20 line has to do with an address line used in memory management.
The system appears to otherwise function normally. I know I have *not*
seen this WARNING message on other systems as they boot up. Any
insights/explanations appreciated!
