Hello,
we're trying to get to work IBM X-Windows for IBM DOS Version 1.1,
from Locus Computing Corp. It works quite fine, but it quickly runs
out of memory (three beeps and than a crash). It is very slow, but we
think this is caused by the limited amount of memory. We use a PS/2 60
with 6MB extended memory. The extended memory is not used by the
DOS X-Server.
To solve this we thought we'd use the IBM product Above Disc Version 4.0,
from TeleWare West inc. This is a utility that makes extended memory
or disc-memory look like expanded memory. The DOS X-Server from Locus
provides an option '-ems' which should enable expanded memory.
The manual states for this option:
'The DOS X-Server uses expanded memory by making it look like additional
DOS memory. This limits the amount of expanded memory to the size of the
EMS 'window'. For EMS version 3, the limit is 64K. For EMS Version 4,
it may be greater than 64K depending on the capability of your EMS board
and memory manager.'
It turned out that the DOS X-Server alone had more free memory than
combined with 3MB extended memory looking like expanded memory.
It seems to me that Above Disc requires more than 64K system memory,
so that using it with a window size of 64K reduces the amount of memory.
Can anyone comment on this ? Has anyone experience with this combination
of software ? Is it possible to increase the 64K window in Above Disc ?
Is it possible for the DOS X-Server to 'see' more memory than the window ?
Is anyone from Locus or TeleWare West listening ?
Waiting for your reactions,
Derk
