Missing Extended Memory After Restarting from MS-DOS Mode

• Microsoft Windows 95 OEM Service Release 2

SYMPTOMS

After you type "win" to restart Windows 95 from MS-DOS mode, your computer may seem to have lost 2 MB of extended memory.

CAUSE

This problem can occur if you are using QEMM version 7.50 with OEM Service Release 2 (OSR2).

RESOLUTION

To resolve this issue, use any one of the following methods:

- Type "exit" instead of "win" to return to Windows 95 from MS-DOS mode.

- Upgrade to QEMM version 8.0 or later.

- After you restart Windows 95 by typing "win," shut down and restart

  the computer.

MORE INFORMATION

In OSR2, loading Win.com automatically starts SmartDrive. This is not normally a problem because SmartDrive is released by Win.com in the transition from real mode to protected mode. QEMM, however, allocates specific extended memory that Windows 95 cannot reclaim when Win.com unloads SmartDrive. The memory that cannot be reclaimed is the memory used by SmartDrive.
