This article was previously published under Q137755
SYMPTOMS
When you are using Windows 95 on one of the following computers with more
than 16 MB of RAM, Windows 95 reports that only 16 MB of RAM are present:
- IBM PS/2 Model 77
- IBM PS/2 Model 90
- IBM PS/2 Model 95
- IBM PS/Note 425 model 2618-M40
CAUSE
These computers use a nonstandard API for reporting memory in excess of
16 MB that is not supported by Windows 95.
RESOLUTION
STATUS
This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit
http://www.microsoft.com/windows.
MORE INFORMATION
The computers listed in this article use INT 15 ax=c700h to report memory
above 16 MB. (Other IBM PS/2 Microchannel computers may use INT 15
ax=E881.) The updated version of Himem.sys accepts a /P switch that causes
HIMEM to use this API to detect memory in excess of 16 MB. Without the /P
switch, the updated HIMEM does not use this API, and functions the same as
the shipping version of HIMEM.
The new version of Himem.sys reports itself as version 3.95, the same as
the shipping version.
