ID:ET Will DESQview use ExTENDed memory?
Quarterdeck Technical Note
by Dan Sallitt
Q: How do I get at the ExTENDed Memory in my AT?
DESQview uses 64K of extended memory in 80286 (AT) class machines
to run DESQview's code in. This frees up 64K of additional conventional
(below 640K) memory to run your programs in. If the remaining extended
memory is converted into a RAM disk, DESQview can swap programs to
that. Only the first 64K will be used by QEXT, all the rest will be
for data.
ExTENDed memory IS NOT DOS MEMORY. DOS memory is the first 1024K
of memory areas.
ExTENDed memory ALWAYS starts at 1 Megabyte. Programs that access
ExTENDed memory (VDISK, Disk Cache, Print Spooler, etc.) are not
really running their program above 1024K, but rather are using the
memory as "data storage" areas.
You may want to see if you can convert the memory into exPANDed
memory; this kind of memory is much more useful to DESQview and other
DOS programs as well.
