- ================================================================
-
- Please Read Entire Document for Full Explanation of Procedures
- ----------------------------------------------------------------
-
-
- AUTOCAD VERSION 10
-
- AutoCAD V10 386 is not compatible with OS/2 2.x. If you
- want to run AutoCAD V10, it must be the Standard AutoCAD V10.
-
-
-
- AUTOCAD VERSION 12
-
- 1. There are several levels of AutoCad V12; C1, C2, and C3.
- AutoCAD V12 must be at level C2 or C3 to run under an OS/2
- 2.1 DOS session.
-
- 2. There is a fix available from AutoDesk that updates level
- C1 to level C2. Please call Vendor for update. Details
- below for "PHARLAP DOS EXTENDER FOR AUTOCAD V12 C1".
-
- 3. For optimum performance of AutoCAD under OS/2, make the
- following changes to your OS/2 DOS Full Screen Session
- settings.
-
- DOS_FILES = 50
- DPMI_MEMORY_LIMIT = 64
- HW_TIMER = ON
- IDLE_SECONDS = 60
- IDLE_SENSITIVITY = 100
- EMS_MEMORY_LIMIT = 0
- XMS_MEMORY_LIMIT = 0
- DOS_HIGH = ON
- DOS_UMB = ON
- VIDEO_8514A_XGA_IOTRAP = OFF
- (8514 and XGA video card users)
-
-
-
- PHARLAP DOS EXTENDER FOR AUTOCAD V12 C1
- ----------------------------------------------------------------
-
- The AutoDesk AutoCAD Release 12 PharLap Patch is supported and
- on Compuserve in the ACAD Forum. The file, OS2PCH.ZIP is in the
- WHAT'S NEW library.
-
- Type: GO ACAD or ACAD to get to the forum.
-
- You must have IBM's Service Pak XRO6200 or XR06300 OS/2 2.1, or
- XRO6100 for OS/2 2.0 installed to run AutoCAD V12 C1 in an OS/2
- VDM (DOS) session.
-
- NOTE: You should obtain the IBM Service Pak directly from IBM.
-
- A new PharLap DOS Extender, version 4.1-ACAD2, when accompanied
- with the OS/2 Service Pak from IBM, allows AutoCAD V12 C1
- to run in an OS/2 2.0 or OS/2 2.1 Full Screen DOS session.
-
- DOS Extender 4.1-ACAD2 is an update to version 4.1-ACAD which
- AutoCAD V12 C1 currently uses. The DOS Extender is an integral
- part of AutoCAD.
-
-
-
- DOS EXTENDER 4.1-ACAD2 BENEFITS
- ----------------------------------------------------------------
- Ability to run AutoCAD V12 C1 in a full screen OS/2 DOS session.
-
- NOTE: This update should only be done if you want to run
- AutoCAD V12 C1 in an OS/2 2.x DOS session. The
- environment for running AutoCAD in an OS/2 Dos session
- is similar to running within a DOS session under
- Windows 3.1. Please refer to the section "Running
- AutoCAD 386 under Windows" in the Release 12
- Installation and Performance Guide.
-
- It is necessary to update the display driver
- RCPSVADI.EXE. This is more commonly known as the
- SVADI driver. A new version of this driver is
- enclosed on the update diskette.
-
-
-
- UPDATING AUTOCAD 12 C1 TO USE DOS EXTENDER 4.1-ACAD2
- ----------------------------------------------------------------
-
- The NEWDX.EXE program, on the DOS Extender update
- diskette, removes DOS Extender 4.1-ACAD from AutoCAD V12
- C1 and replaces it with version 4.1-ACAD2.
-
- NEWDX works with AutoCAD R12 C0 and AutoCAD R12 C1. If you are
- using a digitizer, we recommend that you upgrade to AutoCAD
- V12 C1 for improved digitizer performance.
-
- This procedure should be done on the installed copy of AutoCAD
- V12 C1, and NOT on original diskettes.
-
- 1. Change directories to AutoCAD V12 C1 executable directory.
-
- CD\ACAD and press Enter
-
- 2. Back up your copy of ACAD.EXE
-
- COPY ACAD.EXE ACADSAV.EXE and press Enter
-
- 3. Copy DOS Extender update program into executable directory
-
- COPY A:NEWDX.* and press Enter
-
- 4. Execute the program NEWDX.EXE
-
- NEWDX ACAD.EXE and press Enter
-
- 5. NEWDX preserves any DOS Extender switch settings that you may
- have had in the earlier version of the DOS Extender.
-
- 6. If for any reason you encounter problems with DOS Extender
- version 4.1-ACAD2, copy saved executable to ACAD.EXE.
-
- COPY ACADSAV.EXE ACAD.EXE and press Enter
-
- 7. Update the RCPSVADI.EXE driver.
-
- CD\ACADR12\DRV and press Enter
- COPY RCPSVADI.EXE RCPSVADI.SAV and press Enter
- COPY A:RCPSVADI.EXE and press Enter
-
- The updated driver contains a work around for an OS/2 bug.
- It works in all environments.
-
-
-
- VIDEO RESOLUTION
- ----------------------------------------------------------------
- Run AutoCAD V12 C1 at 600x480x16 or 800x600x16 display
- resolution. Higher resolutions or more colors may cause problems
- unless the display driver has an intelligent screen grabber.
-
-
-
- GENERAL OS/2 SYSTEM REQUIREMENTS
- ----------------------------------------------------------------
-
- OS/2 runs AutoCAD V12 C1 much better with 16MB than 8MB. The
- time between applications improves. More memory may be required
- if you want to run multiple sessions of AutoCAD.
