CAUSE ===== QEMM versions 7.03 and later install a utility called DOSDATA.SYS in the CONFIG.SYS file. When this file is read, it forces the computer to reboot so that it can optimize memory allocations made from the first boot cycle.

Press F4 when you see the "Starting Windows 95" message. 2. The computer reboots after DOSDATA.SYS is read and displays "Starting Windows 95" again. 3. Press F4 when you see "Starting Windows 95" the second time. This allows the computer to continue booting MS-DOS. -or- 1.
