I have P-III 750 MHZ with WIN'98 loaded on it. While starting up the system gets rebooted again and again. My investigation shows that while loading the HIMEM.SYS this rebooting is happening. I had tried replacing the existing himem.sys with a freshcopy but to no avail. If i boot the system thry step-by-step confirmation mode and bypass the device=himem.sys directive, it boots to command prompt without any problem but windows won't load due to non availability of himem.sys file. Please help.

I suspect that your himem.sys is not the problem.

You may have either bad, or incompatible memory.
Even if the memory tests okay in the POST, it can be bad. Or at least unusable in Windows.

If you have over 511MB of RAM, Windows may not be able to interpret the amount of RAM correctly, and thinks it has no upper memory.

Double check your memory for being seated correctly in the sockets.
If you have multiple sticks, consider trying them out one at a time to see if one is bad.
Also, check for a BIOS update.

I have an Intel PIII MB that wouldn't deal with 2 RDRAM DIMMs until I updated the BIOS.
