SYMPTOMS
When you upgrade Windows 95 to Windows 98, you may receive the following
error message during the Scandisk portion of Windows 98 Setup:
Setup cannot check your hard disks for errors because there is not
enough conventional memory available, free more conventional memory and
rerun setup.
RESOLUTION
To resolve this behavior, increase the amount of free conventional memory,
and then run Windows 98 Setup again. To increase the amount of free
conventional memory, use either or both of the following methods:
Method 1
Using a text editor (such as Notepad), add the following lines to the
Config.sys file and then restart your computer:
device=c:\windows\himem.sys
device=c:\windows\emm386.exe noems
dos=high,umb
Method 2
Using a text editor (such as Notepad), disable all non-essential drivers
and programs in the Config.sys and Autoexec.bat files, and then restart
your computer. To disable a driver or program, type "rem" (without
quotation marks) and then SPACEBAR at the beginning of the line. Make sure
to disable any real-mode driver for which there is a protected-mode
equivalent.
For additional information about how to increase the amount of free
conventional memory, please see the following article in the Microsoft

NOTE: Once Windows 98 is installed, you can re-enable any lines in the
Config.sys or Autoexec.bat file that you disabled.
