NOTES ON USING APPLICATIONS WITH MS-DOS VERSION 5.0This document provides important information not included in the Microsoft MS-DOS User's Guide and Reference or in online Help. Look through the following table of contents to determine whether your application is included. ATTENTION CODEVIEW AND INTEL ABOVEBOARD USERS +++++++++++++++++++++++++++++++++++++++++++++ Sections 1 and 4 contain critical information about using Intel Above Board and CodeView with MS-DOS 5.0. +++++++++++++++++++++++++++++++++++++++++++++ For information about installing MS-DOS 5.0 and using hardware and networks with MS-DOS 5.0, see the README.TXT file. The following topics are discussed in this file:
CAUTION: The Intel Above Board installation program that shipped before May 1989 tests extended memory in a way that can corrupt extended memory.Before using an Above Board installation program prior to May 1989, make sure you haven't loaded software such as SMARTDrive or RAMDrive that uses extended memory. After the Above Board has been installed, other software using extended memory is unaffected.
When running AutoCad 386 under Windows 3.1, note the following:
* AutoCad 386 runs in standard mode only if no LIMulator is installed. To run in 386 enhanced mode, you must upgrade to AutoCad for Windows.* The PIF setting for AutoCad 386 are set for a minimum configuration. Using these setting results in poor performance. To improve performance, you can modify the PIF settings, as described below. PIF Settings ------------ To improve the performance of AutoCad 386, make the following changes to the standard mode PIF: XMS MEMORY REQUIRED should be set to 1. This forces XMS memory tobe provided to an application. Unless a required amount is listed, no XMS memory is provided. XMS MEMORY DESIRED should be set from 1024 to 4096. 1024significantly improves performance. The manufacturer recommends 4096 for best performance. OTHER REQUIREMENTS: For these settings to work, you must have adequate XMS memory available. If there is not enough, no adverse effects are apparent, but performance is only improved by the real amount of XMS provided. You must also have an equivalent amount of disk space free for a swap file.
To start CodeView versions 3.0 to 3.13 safely, use the CV.COM file included with MS-DOS 5.0, and HIMEM.SYS version 2.77 or later. To use the CV.COM file included with MS-DOS 5.0, copy it from the Setup disks to the directory that contains your CV.EXE file. This problem has been fixed in CodeView version 3.14. Call Microsoft C Support to get this version.
LOADFIX FB.EXE or LOADFIX FBINSTAL.EXE For information about the LOADFIX command, see the section "You receive the 'Packed file corrupt' message" in Chapter 4 of Microsoft Windows and MS-DOS Getting Started.
SETVER GEOS.EXE 4.01 Do not run the installation program for GeoWorks Ensemble when MS-DOS Shell Task Swapper is active. Use the Exclusive Tasking option when running GeoWorks Ensemble with Windows.
There is no compatibility problem with the network version.
If you have a PC-Kwik cache on your system, and you can't run a packed program, do one of the following: * Use the LOADFIX command to start the program. * Run MS-DOS 5.0 in conventional memory. * Run a version of the program that was not packed with Pklite. * Disable asynchronous reads on the PC-Kwik cache.For information about the LOADFIX command, see the section "You receive the 'Packed file corrupt' message" in Chapter 4 of Microsoft Windows and MS-DOS Getting Started.
ProKey Plus is incompatible with MS-DOS Editor and QBasic.
LOADFIX sk2.exeFor information about the LOADFIX command, see the section "You receive the 'Packed file corrupt' message" in Chapter 4 of Microsoft Windows and MS-DOS Getting Started.
If you installed HIMEMSLS.SYS, remove the DEVICE=HIMEMSLS.SYS command from your CONFIG.SYS after installing MS DOS 5 on your system. To use DOSKEY, load it after you load Software Carousel into memory.
