I've just purchased MS-DOS Version 5.0 this past week. I installed it
and believe it or not, it worked the first time the system booted.
Here are some tips that might be useful to anyone who is contemplating
purchasing and installing DOS 5.0.
1. Read the "Getting Started" book from cover to cover. If you are
running a network, you will have to concern yourself with the
the network software you are running and its version.
Also, read the following text files on your diskettes before
you begin the installation.
README.1ST on diskette #1
README.TXT on diskette #5
APPNOTES.TXT on diskette #6
2. Backup all of your hard disk drives before you attempt to
install the product. Although my system had no problem in
this area, the instructions uge you to do this. DOS 5.0 may
have to change your partitions if you are running special
partitioning software.
3. If you are running 4DOS, remove it from the system and use
COMMAND.COM. 4DOS verion 3.02 and up does work with DOS 5.0.
You can re-install 4DOS later.
4. Remove all TSR's from your system and reboot it before installing
DOS 5.0.
5. Save a copy of your AUTOEXEC.BAT and CONFIG.SYS files for later.
This will be especially useful if you have a lot of started
programs and device drivers.
6. Before you begin installation, you will need 2 or 3 blank
diskettes. DOS 5.0 automatically uninstalls your old version
of DOS and puts it on two diskettes. You will need the other
diskette to make a bootable system for emergency purposes.
7. You can now begin the task of installing DOS 5.0.
Just put your first diskette in the drive and type SETUP.
The SETUP program will determine your system type and
available hardware during the installation process.
You will have the option of overriding the following options:
a. Whether you are installing DOS 5.0 on a network system
b. Whether you want the DOSSHELL program to start automatically
when system is booted.
c. Select the type of monitor you have on your system for
for DOSSHELL program.
8. The installation takes anywhere from 10 to 30 minutes depending
on the type of system you are running. When the installation
is completed, the SETUP program will tell you to remove the
diskette from the drive and press any key to boot your system
which now contains DOS 5.0. The FIRST thing you should do
is to make a bootable diskette for DOS 5.0. Just type
SYS A:.
9. When the system boots, you will have to put your TSR's
and 4DOS back in your AUTOEXEC.BAT and CONFIG.SYS system.
10. Special Notes:
a. If you have your own extended memory manager, (e.g., QRAM, QEMM,
386MAX, etc), leave them in your system. DOS V5.0
will load approximately 30K of its kernel in the HMA
area if you have an AT and have more than 1 meg of memory.
If you do not have a extended memory manager, DOS 5.0
will use its HIMEM.SYS to give you these benefits.
b. You can also gain some conventional memory if you can
use UMB's (upper memory blocks) to contain device drivers
and TSR's. DOS 5.0 gives you a "DEVICEHIGH" parameter
for CONFIG.SYS for device drivers and a "LOADHIGH" command
to use in your AUTOEXEC.BAT file for TSR's.
NOTE!: You can only use "LOADHIGH" and "DEVICEHIGH" is
your you use the HIMEM.SYS extended memory manager that
comes with your DOS 5.0. If you are using a different
extended memory manager, you must use the equivalent
programs that it comes with.
11. SOME NEAT FEATURES OF DOS 5.0.
a. The DOSSHELL program that comes with DOS 5.0 is much
better than the one that came with 4.0. It takes a lot
getting used to, but it makes life easier.
b. The QBASIC that comes with DOS 5.0 is very similar to
QUICK BASIC with the exception that you can not create
a load module. It comes with its own editor which makes
writing and executing BASIC easy.
c. DOS 5.0 also comes with its editor (which is really the
QBASIC editor) and can be used to create and update
text files. With this you can throw away EDLIN.
d. Another neat enhancement it that DOS 5.0 comes with
three new commands. UNFORMAT, UNDELETE, and MIRROR.
If you think these names sound familiar, you are right.
These are the same three utilities that come with
PCTOOLS from Central Point Software.
I hope everyone has the same luck I had with installing DOS 5.0.
