New UIDE Available (Announce)

> Jack R. Ellis has released another update.

I have a suggestion for Mr Ellis, apropos his high mem manager (XMGR.SYS).
Can he be contacted either directly or through you ?

The point I wish to make - no reason to make it in private - is that sadly, xmgr asks the BIOS (int 15/AH=C0 iirc) for the presence of PS-2 style "port 92" HMA management and reverts to plain old "keyboard controller" type if BIOS doesn't report its port 92. Unfortunately many chipsets (most indeed) have port 92 A20-gate (and Reset) available for use, but still fail the PS2 int15 check.

I think it would be beneficial to ask Mr Ellis to add a command line switch meaning "bypass the int 15-PS2 test and try to use port 92h anyway. (MS DOS himem.sys has a /machine: switch)

Of course since source is provided it is easy for most of us here to modify it for one's sake but this is so generally useful an addition that ISTM best is to ask the author/maintainer for it.

Regards...
