SYMPTOMS
Versions of HIMEM.SYS earlier than 3.10 may not recognize more than 64
megabytes (MB) of memory on EISA bus computers.
CAUSE
This is because HIMEM.SYS does not recognize EISA memory blocks that start
between 64 MB and 65 MB. On these machines, HIMEM.SYS only sees 64 MB of
memory.
NOTE: MS-DOS 6.2 and Windows for Workgroups version 3.11 provide
HIMEM.SYS version 3.10.
