When you run Setup again from the MS-DOS prompt after your computer lost
power (or you turned it off) while you were upgrading Windows version 3.x
to Windows 95, you may receive the following error message:
Not enough XMS memory to run Setup. Please free up <xxx> amount of
XMS and re-run Setup.

This problem can occur on computers with 4 MB of RAM if the computer loses
power or is shut off while you are upgrading Windows 3.x to Windows 95.
Depending on where in the installation process power is lost, Setup may
have copied enough files to the Windows folder that the original version
of Windows does not function correctly. When you run Setup from an MS-DOS
prompt, a 4-MB computer may not have enough extended memory for Setup to
run.

Disable all unnecessary programs and TSRs in the Config.sys and
Autoexec.bat files. If you are running Setup from floppy disks or a
flat directory, and no special drivers are necessary to start the
computer, you can bypass the startup files and the loading of drivers by
pressing the F5 key when you see the "Starting MS-DOS" message.
