This article was previously published under Q96695 SUMMARY
Many software installation programs modify the CONFIG.SYS and AUTOEXEC.BAT
files. Most installation programs that modify the CONFIG.SYS file add lines
to either the top or the bottom of this file. If you are using multiple
configurations, these modifications may cause problems.
MORE INFORMATION
The most common problem occurs when an installation program updates a
specific driver in the CONFIG.SYS file when multiple instances of that
driver exist. Many installation programs update only the first or last
occurrence of a driver. You can avoid multiple occurrences of device
drivers in the CONFIG.SYS file by using a [COMMON] section.
If you include a [COMMON] block at the end of your CONFIG.SYS file,
you can usually avoid problems with installation programs that add
lines to the bottom of the CONFIG.SYS file.
