acad and dos5
Tom,
You're using HIMEM.SYS and EMM386.SYS aren't you……..<grin>. The problem
comes in because the Phar Lap DOS extender version 2.2 is not DPMI
compatable (that's the type of memory that HIMEM and EMM386 give you). So
to correct the problem you have to upgrade the DOS extender that is part of
the ACAD.EXE. To do this, first download the file called NEWDX.EXE from the
data library 10 [Utilities] and open it up. Then copy your existing
ACAD.EXE to a new file like ACADOLD.EXE. Then NEWDX ACAD.EXE. The NEWDX
program will convert the existing Phar Lap code to version 2.6 which is
DPMI compatable.
There is another feature added by NEWDX and that's called demand loading.
There is a new switch that when activated will only load as much of the
ACAD.EXE as is required to load your drawing and will load the rest as you
need it. This switch was added to make loading the drawing editor even
faster.
