-
- I have been unable to get any documentation for these systems. If
- you can have your system vendor or the chip set manufacturer
- contact me, I will try to include support for them.

-
- Notes:
- [1] - Support minimal ( maximum 64K UMB area ).
- [2] - Support limited ( maximum 128K UMB area ).
-
- If your chip set is not listed, have your system vendor or the chip
- set manufacturer contact me and I will try to support it.
-
- I now testing a general EMS simulator which will load high with
- UMB_DRVR and will use XMS ( HIMEM.SYS ) memory to supply EMS memory on
- *ALL* systems supported by UMB_DRVR ( 286 / 386 / 486 ). It is able to
- dynamically switch the memory, only using the XMS memory when EMS is
- required. This will be included in the UMBDVR.EXE package at no
- additional charge.
-
- Also in the works are features to save even more precious memory
- below 640K by:
- - loading the primary shell ( COMMAND.COM ) into upper memory
- - relocating all DOS areas possible to upper memory, including
- FCBS=, FILES=, BUFFERS=, STACKS=, and LASTDRIVE=
- - allowing the lower portion of the video ram area to be switched
- in and out to expand DOS base ram beyond 640K but not inhibit
- graphics modes ( only for chip sets with video area support )
-
- A newer, more flexible ( read as less Neanderthal, approaching the
- Bronze Age ) user interface is coming as soon as I get the time.
-
- I have ( I think ) found a way to *reliably* test for and list the
- chip set in a machine. I will be including a separate program to do this
- in the package soon. Of course, it will only recognize the chip sets it
- supports, so a negative result will not necessarily mean you have a chip
- set that will not be supported later.
-
- If there is enough interest, I will also write device-specific EMS
- drivers for the hardware facilities in the EMS-capable chip sets. Please
- Email or surface mail your thoughts ( no phone calls on this, please -
- save those for support questions ).
