There isn't much to go on here.  However, when I first installed
QEMM V5.00 on my 20Mhz AT/386, which uses the Chips &
Technologies CS8236-20 chipset, QEMM would reboot indefinitely in
the manner you describe.

I discovered that by default QEMM was assuming that my C&T
chipset supported "shadow RAM".  Whether or not this is true,
disabling "shadow RAM" support, by putting the NOSH switch on the
QEMM.SYS command line, eliminated the reboot loop.  My current
QEMM.SYS command line looks like this:

    DEVICE=C:\QEMM\QEMM.SYS NOEMS NOSH NR MAPS=0 X=0000-BFFF
           RAM ROM=C000-C7FF ROM=CC00-CDFF EXTMEM=1072

Newmarket, Ontario, Canada     :  TelePoker will be there - will YOU?
