From the above file:
"When you boot your computer, HIMEM is loaded from your
CONFIG.SYS file. After it is loaded, you will see a message like
the following telling you the method HIMEM will use to access
extended memory on your computer.
Installed A20 handler number X.
where X is 1 through 8 which corresponds to one of the
following methods:
Number Name Computer type
--------------------------------------------------------------
1 at ; IBM AT or 100% compatible.
2 ps2 ; IBM PS/2
3 ptlcascade ; Phoenix Cascade BIOS
4 hpvectra ; HP Vectra (A & A+)
5 att6300plus ; AT&T 6300 Plus
6 acer1100 ; Acer 1100
7 toshiba ; Toshiba 1600 & 1200XE
8 wyse ; Wyse 12.5 Mhz 286
If HIMEM does not work properly, you can try a different method.
Specify the switch for your computer type on the
device=HIMEM.SYS line in your CONFIG.SYS file. Computer type
corresponds to either the number or the name of your computer
from the table.
For example the following lines are equivalent:
device=c:\himem.sys /M:ps2
device=c:\himem.sys /M:2
This entry forces HIMEM to use the IBM PS/2 A20 method for
accessing extended memory."
So you might want to change this switch...
