>>>I have a Pentium 100Mhz machine with a 1.2GB super IDE HDD, 16MB of RAM and 1.44MB FDD.

>>>On the Performance page in the System Properties in Control Panel, the File System (in the Performance Status) reads 'Some drives are using MS-DOS compatibility' and the Virtual Memory states 'MS-DOS compatibility mode'.

>>>In the Item Details list on the same page, the first line indicates 'Compatibility mode paging reduces overall system performance.' The next two lines mentions both the drives that I have on the machine, viz. Drive A: and C:. The lines states that the drives are using MS-DOS compatibility mode file system.

>>>As stated in the Windows Help, I checked my startup files, Config.sys and Autoexec.bat, but there are no drivers which Windows might no recognize. The only drive I using is Himem.sys.

>>>Due to this problem, the system performance is reduced drastically. I have similar machines with similar hadware configurations as well as same set of Config.sys and Autoexec.bat files which gives a far better performance. Moreover they do not register this problem.
