INCLUDE--Examples The following CONFIG.SYS file defines three configurations: [menu] menuitem=base_config, Base configuration only menuitem=full_config, Normal configuration menuitem=net_config, Normal configuration with network [base_config] dos=high device=c:\dos\himem.sys [full_config] include=base_config dos=umb device=c:\dos\emm386.exe ram devicehigh=c:\dos\ramdrive.sys 512 [net_config] include=full_config devicehigh=c:\net\network.sys [common] This CONFIG.SYS file contains four configuration blocks. The [base_config] block contains two typical CONFIG.SYS commands. The [full_config] block includes the commands in [base_config] plus the DOS=UMB command, a DEVICE command, and a DEVICEHIGH command. The third configuration, [net_config], includes all the commands in [full_config], which in turn includes those in [base_config]. The [common] block appears at the end of the CONFIG.SYS file. It is a good idea to end your CONFIG.SYS file with a [common] block so that installation programs can successfully append commands to your CONFIG.SYS file.
