Thanks for looking into this. There is also a page in the FreeDOS wiki about
the problem:
http://sourceforge.net/apps/mediawiki/freedos/index.php?title=VirtualBox_-_Chapter_9
As I wrote, KEYB v2.01 and JEMMEX v5.75 are installed in a way in FreeDOS 1.1
that leads to KEYB crashing at boot
- if you choose option 1 from the boot menu and
- manually changed AUTOEXEC.BAT to install a keyboard layout.
Generally spoken this means people with a different keyboard than the US have a
problem.
AFAIK there are two ways to work around this as user:
1. Solution: Change the following line in FDCONFIG.SYS
1?DEVICE=C:\FDOS\BIN\JEMMEX.EXE NOEMS X=TEST I=TEST NOVME NOINVLPG
to read
1?DEVICE=C:\FDOS\BIN\JEMMEX.EXE NOEMS I=TEST NOVME NOINVLPG
(remove X=TEST)
Or
2. Solution: Change the following line in AUTOEXEC.BAT (if you install f.i. the
german keyboard layout)
KEYB GR,,keyboard.sys
to read
KEYB GR,,keyboard.sys /NOHI
Effects on free memory:
1st solution: 598,736 total 594,656 conv 4,080 upper
2nd solution: 590,560 total 590,208 conv 352 upper
So the first solution gives me more free memory while the second solution may
result in a more robust system (more tested and excluded upper memory blocks).
Of course from a user's perspective it would be best if either KEYB or JEMMEX
could be fixed. According to your remarks it should be JEMMEX. I just tested
the new JEMMEX v5.76 but there was no difference.
