I cant run any DOS programs that require EMS memory on  
my computer. When I try I get this message: “you must have  
at least (somenumber)k of expanded memory”. When I right  
click on the program and goto properties then memory it  
says: “the computer is not configured for expanded memory  
in MS-DOS sessins”. Details say: “Third-party  
memory-management software has not been configured for  
expanded memory.”. I am using windoze 98. Thank you.

Put these statments in your config.sys file and make sure the himem.sys and emm386.exe are either in your root directory or that the locations in the statements point to where they are actually located. They are normally in c:\windows\command directory in win98.

Device=c:\Himem.Sys  
Device=c:\EMM386.Exe  
DOS=SINGLE  
DOS=HIGH,UMB

The sysedit.exe utility in the c:\windows\system directory is a handy way to edit the config.sys file and other boot files.
