SYMPTOMS
========
The automatic A20 handler detection scheme employed by HIMEM.SYS in MS-DOS may
not install the proper A20 handler on SAMSUNG S-5200 computers.
CAUSE
=====
On SAMSUMG S-5200 laptop computers, HIMEM.SYS may install A20 handler number 1.
This may result in erratic behavior on the machine when extended memory is
accessed.
WORKAROUND
==========
To correct this problem, the A20 handler number 12 should be installed. Add the
following line to the CONFIG.SYS file to install the proper handler:
device=c:\dos\himem.sys /machine:12
