This is one of the things my A+ certification didn't exactly
cover..How the heck do you upgrade a DOS installation? My old
IBM PC-XT has DOS 4 on it.. I booted a DOS 5 floppy, and
noticed Windows 3.0 seems to run a little faster with it...
But, how do I update the installation, WITHOUT erasing
the contents on the HD? With a 720KB floppy drive,
backing up is quite hard to pull off..
You could use a dos upgrade version or with a full version I suppose you could delete the dos directory, io.sys, msdos.sys and command.com on the hard drive and then run the installation. A full version installation doesn't need a blank hard drive in order to install.
You'd probably want to rename the existing config.sys and autoexec.bat to something else so you could incorporate any differences between your existing files into the default ones the installation will create.

hmm, im using a bootdisk version of DOS 5.. I don't have a
full installation anymore (lost it via age--disk lost the
magnetism)Is it possible to "sys" it?

Yeah, you could sys it with the bootdisk but the other dos files would still be ver. 4 and may not run without adding them all to the setver command.

my bootdisk has a bunch of DOS files, i'll just use Windows
3.0 on it and copy and replace them all...IW2EVK: There is no way that this computer can boot a
FreeDOS installation, I've tried, I just get a blank screen and
it haults (not to mention, I don't think that'll work with
Win30..)

Go for version 6.2xCheck out the SYS command and then copy the
rest of the files.Due to the smal capacity floppy it may be best to use PKZIP for copying which compresses the files and spans floppies.
Good Luck. Keep us posted.

"DOS 6 don't boot on this system either.."
I ran M$-DOS 6.22 happily on a 8086 Amstrad IBM Clone, so maybe you have other problems ??

Did it act like the drive did a seek and settle and attempt to read? Will it boot a DOS 4/5x 720K?

If at first you don't succeed, you're about average.M2

If it's trying to load himem, that might bomb the boot. Try renaming config.sys & autoexec.bat

I know it's not himem.sys, cause when I boot DOS 5 on it, (which the boot disk tried to load), it did give a beep, then gave a message saying it required an 80x86, and the driver wouldn't be installed (then it continued booting fine)..
Remember, this old PC has "two" BIOS's, so it might be conflicting with the "ABIOS"...

ok, got DOS 6.22 booting.. it was a "my bad" type of thing
XDI was formatting it as 720K on my Domain Controller (only
computer in my house that has a floppy on a modern PC),
and I forgot to tape over the media sense hole...

argh, spoke too soon..
I can no longer use MS-EDIT.. I get "run-time error R6003 -
integer divide by 0" now...

If you're using a 6.22 bootdisk (or sys'd the HD with 6.22) and are running EDIT or other commands from the older 4.0 dos, that may be the problem.

Make sure QBASIC.exe in on your boot disk if you want to run EDIT...it must be in the same directory.

The following is from “help edit” at an MS-DOS6.22 prompt, then at the bottom of the page.
“CAUTION: MS-DOS Editor does not work if the file QBASIC.exe is not in the current directory or in the search path or in the same directory as the file EDIT.COM. If you delete QBASIC.exe to save space on your hard disk, you cannot use MS-DOS EDITOR.”

it doesn't, i've tried it.. it don't give an error now, it just
hangs the computer...being it used to work, and when i booted up DOS 5, it DID
work, DOS 6.22 seems to have damaged support for this
computer in some ways.. I might downgrade back to DOS
5...

If you are upgrading the same kind of DOS (ie MS-DOS 3.x to 6.x, or PC-DOS 3.x to 7.x or Windows 9x, you can simply replace the DOS files on the hard drive. Don't forget the ibmbio.com/io.sys and ibmdos.com/msdos.sys.
If you are changing DOS types, you need to SYS the drive to install the new boot sector.
Otherwise, you pretty much can have several DOS from the same vendor, and simply replace the boot files (ibmbio.com, io.sys, ibmdos.com, msdos.sys, command.com, config.sys and autoexec.bat), as the need sees it.
The dream you dream alone is only a dream,
The dream we dream together is reality.
