[FIXED IN SVN] EMM386 does not automatically detect the available UMB regions

Description (last modified by )
If MS-DOS virtual machine is created and EMM386.EXE is used, VirtualBox cannot automatically detect available UMB regions, so they are needed to setup manually to the CONFIG.SYS-file, like:
DEVICE=C:\WINDOWS\EMM386.EXE RAM ON NOEMS FRAME=NONE I=E000-EFFF I=B000-B7FF
On the contrary, Microsoft Virtual PC 2007 can do this. Command
is enough and UMB regions will be detected.
This is not a big problem for advanced users who are able to do a manual edit and people who are running only small programs on MS-DOS virtual machines may not need it at all. It can be confusing for the others. I do not consider this is a bug, so let's say that this is a feature request.
