Thanks to Michael, Chris and Eric for replying to the list or directly.
The number of permutations of a half-dozen command options is rather large,
so I didn't test every possibility. But I think I hit all of your
suggestions:
In my test configuration, I had no AUTOEXEC.BAT and this 3-line CONFIG.SYS:
DOS=UMB
DEVICE=C:\FDOS\BIN\HIMEM.EXE
DEVICE=C:\FDOS\BIN\EMM386.EXE various test options here
My results with various EMM386 options:
1) X=TEST
Ctrl-Alt-Del failed to work
2) NOEMS NOVDS X=A000-EFFF
Ctrl-Alt-Del failed to work
3) NOEMS NOVDS X=A000-EFFF NOALTBOOT
Ctrl-Alt-Del worked, though I don't know what NOALTBOOT does
4) NOEMS NOVDS X=A000-EFFF NOALTBOOT MEMCHECK
Ctrl-Alt-Del also worked here, though I don't know what MEMCHECK does
I want as much function as I can get, so I also tested the default options
(from the bootable CD install) + NOALTBOOT:
5) NOEMS X=TEST VDS NOALTBOOT
Ctrl-Alt-Del also worked here
-----------------------
But Ctrl-Alt-Del failed once again when I inserted #5 in my original
CONFIG.SYS:
SWITCHES=/F/N
COUNTRY=001,858,C:\FDOS\BIN\COUNTRY.SYS
SET LANG=EN
LASTDRIVE=Z
BUFFERS=20
FILES=40
DOS=HIGH,UMB
DOSDATA=UMB
SET DIRCMD=/OGN /4
DEVICE=C:\FDOS\BIN\HIMEM.EXE
DEVICE=C:\FDOS\BIN\EMM386.EXE NOEMS X=TEST VDS NOALTBOOT
DEVICEHIGH=C:\CDROM\OAKCDROM.SYS /D:FDCD0001
SHELL=C:\command.com C:\ /E:512 /P=C:\AUTOEXEC.BAT
So I added back a range exclusion, thus: NOEMS X=A000-EFFF VDS NOALTBOOT.
This booted up in unstable condition, locking altogether (or with
Ctrl-Alt-Del still not working).
I increased the exclusion to the range that one of you had recommended:
NOEMS X=A000-FFFF VDS NOALTBOOT. This booted into stable, functional
condition, and Ctrl-Alt-Del works. But EMM386 notes when it loads that "no
suitable memory block found," and I see that this configuration produces no
available and free upper memory. Nothing loads high - everything goes into
conventional memory.
Any ideas for making this work better?
