himem.sys doesn't load

Sounds like the himem.sys file is corrupted.  Try replacing it with another copy, and make sure no devices are trying to load before it does (which shouldn't be possible with 95).

Your himem.sys is likely not corrupted.  Himem will try to determine certain things about your machine when it is loaded, but it doesn't always work.  You will need to add a couple of switches to the device= line, specifically /cpuclock and /machine. Edit your config.sys file, and change the Himem.sys line to something like 'device=c:\windows\himem.sys /cpuclock:on /v /machine:x'  <-- the value of 'x' here is the important part.  You didn't mention what type (manufacturer) of computer you have, but 1 (just the number 1) is almost a generic type, and will often work.  If it doesn't, see MS Knowledge base article Q96711 ...

Hope this helps.

If you wanted to load another copy of hymem.sys. Get a copy on a cd. restart the machine in dos mode. change to windows. Erase himem.sys. and copy hymem.sys to the same location.

I think you have a hardware problem, especially with your recent past history of corruption.
Get a DOS boot disk and just have himem.sys load through config.sys and nothing in autoexec.bat.  That will remove software problems from the equation.

Have you upgraded/changed RAM or Cache lately?

mem100,

I can figured it out that you upgraded to Windows 95 from Windows 3.1 with the DOS on it.

In this case, Windows 95 is still relying on your DOS config.sys.

Check you Config.sys

DEVICE=C:\DOS\Himem.sys
DEVICE=c:\DOS\EMM386.EXE NOEMS

Did you, by any chance, install Norton AntiVirus or SystemWorks ?  If so, take a look at

(sorry about that url).

In any event, Norton AV can have a problem and you need to add the line

SET DOS16M=2

to your autoexec.bat, and perhaps other lines to your config.sys.  It depends on what you installed.

If this sounds like your problem, take a look at the urls, which explain it more precisely along with the fixes.

Go into your Bios Setup and make sure the A20 is enabled.

Actually, I had a similar problem with Norton. I found that the machine would boot from a complete shutdown but not on a restart. To resolve this, go into regedit, go to Edit -> Find, then type in himem.sys and click Find. It should find a key named "himem.sys" with a value of "Device=%winbootdir%\himem.sys". Replace %winbootdir% with the path of your windows directory for example, c:\windows. You should probably remove Norton before you do this.

Sorry, I already got the solution. Actually it was Adriens comment that did it.
Thanks anyway.

Thanks for your comment it worked. I'm willing to give you the points but I think you would have had to answered the question first. If there is another way for me to give yuo the points let me know.
