- Make sure you have the line : DOS=HIGH,UMB in your config.sys. Then you can
- take out the noems i=e000-efff parameter. Replace it with the amount of
- ems you need, e.g. :
-
- device=himem.sys
- device=emm386.exe 4096
- dos=high,umb
- ...
-
- ..will load DOS in the HMA, will make 4096K (4mb) available as ems, and will
- give you access to UMBs for devicehigh and loadhigh statements.
