I haven't tried, but it is possible that there really isn't enough room to load
it high and initialize. Some programs need more room than their resident space
to initialize. There must be enough high room for the maximum size. For example
I have a V& fastwrite VGA card. They supply a utility "altparm" that is a TSR
that monitors the mode switching on the VGA. It can handle several different
monitors and its purpose is to adjust parameters such as height, width,
centering, etc so that the picture stays in about the right place. It needs 44K
initially because it can handle several different monitors. Once it know what
type of monitor, then it stays resident with only that info loaded, about 6K.
This means that I need a 44K chunk of high memory to get it started. It makes
sens in this case to load it first, before all others. The qemm "loadhi /gs"
command is great for finding out this info.
