| 8 | Windows 3.x guests are typically limited to 64 MB RAM, even if a
|
|---|
| 9 | VM is assigned much more memory. While Windows 3.1 is
|
|---|
| 10 | theoretically capable of using up to 512 MB RAM, it only uses
|
|---|
| 11 | memory available through the XMS interface. Versions of
|
|---|
| 12 | HIMEM.SYS, the Microsoft XMS manager, shipped with MS-DOS and
|
|---|
| 13 | Microsoft Windows 3.x can only use up to 64 MB on standard PCs.
|

|

| 15 | <p>
|
|---|
| 16 | This is a known HIMEM.SYS limitation. Windows 3.1 memory limits
|
|---|
| 17 | are described in detail in Microsoft Knowledge base article KB
|
|---|
| 18 | 84388.

|

| 21 | It is possible for Windows 3.x guests to utilize more than 64 MB
|
|---|
| 22 | RAM if a different XMS provider is used. That could be a newer
|
|---|
| 23 | HIMEM.SYS version, such as that shipped with Windows 98, or a
|
|---|
| 24 | more capable third-party memory manager, such as QEMM.
