Cannot load a couple tsr's high #2558

Hi:

Trying to load a couple tsr's high. They are screen readers, and, under MS-DOS, they do load high with no problem.

I use the lh command with default options.

Do I need to install a memory manager for this to work?

Thanks!

I tried the built-in LH command and I don't think it works with UMB memory with the default setting. However, some DOS programs can auto-load into UMB memory by themselves and can indeed load into UMB in DOSBox-X. Two examples are CTMOUSE and COMMAND.COM from MS-DOS 7.x:

CTMOUSE.EXE: ctmouse.zip

COMMAND.COM (MS-DOS 7.1): commmand.zip (Enter the command VER 7.1 before running COMMAND.COM from MS-DOS 7.1).

I guess the LH command may need some work.
