    XMS memory

    Hi folks,
    I have a client who got hit with a virus that corrupted many of her system files. Upon trying to enter safe mode, I encountered the following:
    "HIMEM.SYS has detected unreliable XMS memory at address 00837080 -- XMS driver not installed."

    My question is, is XMS memory virtual or actual physical memory? I tried recopying himem.sys and emm386.exe from a good computer, with no success. The interesting thing is that Windows can load with a normal startup, but hangs when I try to enter safe mode.

    I just want to rule out any physical memory problem before repartitioning & reloading the OS.

    Thanks for any help,

    Charlie T.

    It's actual, physical memory that nearly nothing uses anymore. Try re-running setup without formatting and see if it will restore the boot sector and that driver - my guess would be that the HIMEM.SYS driver is corrupted.

    Hi, it turned out that the memory chip was bad. I replaced it and everything was back up and running with no problems.
