#acad and dos5
3 messages in this thread
I am a registered user of AutoCad release 11. Now that I am using DOS
version 5 everything runs dead slow. I seem to recall someone saying you
need a new ACA D.EXE file. Where can I get this if is it indeed the case.
Thanks.
Tom – you should download two files from the forum's data libraries. First of
all, go to Lib 6 "Opsystms/Networks" and download a file called DOS5.TXT.
This is Autodesk's official position paper on running AutoCAD under DOS 5.0.
Reading it, you'll find mention of a file called NEWDX.EXE. Use this program
to update the Phar Lap DOS Extender that's built into ACAD.EXE to make it XMS
— and HIMEM — compatible. NEWDX.EXE is stored in a zipped archive file
called NEWDX.ZIP and can be downloaded from Lib 10 "Utilities".
If you have Release 11c2 (and you should), you already have NEWDX.EXE on one
of the diskettes.

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.
