MORE INFORMATION
For each device driver (from the above list) that you want to load into a UMB, do the following:

Note: Device drivers are loaded through the CONFIG.SYS file with a DEVICE= line.  Make sure DEVICE=HIMEM.SYS is loaded above the DEVICE=EMM386.EXE line and that the line DOS=HIGH,UMB is in the CONFIG.SYS file. Change the DEVICE= line, which is used to load the following device drivers, to DEVICEHIGH= in the CONFIG.SYS file. For example:

devicehigh=c:\dos\ansi.sys



For each TSR that is loaded in your AUTOEXEC.BAT file and is safe to load into a UMB, add the LOADHIGH (LH) command before the TSR. (LH is equivalent to LOADHIGH.) For example, you can change the line

c:\dos\doskey

to the following:

lh c:\dos\doskey
