just a few questions...

1. Is it possible?

2. Would it work?

3. What are the disadvantages?

4. What would be the best way to go about it?

thanks in advance,

yes it should be possible. I have done it on my win 3.1 and dos 6.0 machine. First you need to have an understanding of how to write comprehensive config.sys files. The book "The only DOS bok youll ever need" I find is really helpful. Youll also need to find out the single file that when executed executes win 98. You should be able to work it out from there.

A simpiler way is to pres F8 or whichever function key it is in win 98 when the "loading windows " screen first pops up (or a bit before this) to bring up the boot menu. This has options of whether you want to boot to DOS or win 98 on it.

1. yes
3.none really

4. Arguably the best way is to use a boot manager, so that when you boot the computer you get a choice of which OS to boot into.

Very briefly:

You will need dos boot disks handy with all the usual utils on them, one with dos 6.22 and one with Win98SE ( the command.com and fdisks are different)
You will need to make 2 primary dos formatted partitions.
Using the boot manager activate each in turn and load the operating system.

Basically all done :) that was quick :D

Here are some urls for free boot managers. (Disclaimer... I havent tried these, Ive only used those that come with Partition Magic, the IBM manager and BootMagic.)

I forgot to say dos6.22/win3.11 will have a FAT16 partition and DOS 6.22 will only recognise up to 2GB.
It is also possible to have a 3rd partition which can be accessed from either OS, its only the primary partitions that are hidden/unhidden by the boot manger.

The other way of doing the same thing is to have separate hard drives, conveniently in plug-in caddies. which is what I have, one for dos 3 + Windows 1.0 :) , another for dos6.22/Win3.11 +dos browser/email, another for Mandrake, another for Win98SE, and lastly one for a weekly back-up.

is it possible. Yes
Would it work. Yes
What are the disadvantages. None

I would advise partitioning up the HDD, and and use a boot manager. for windows 3.11 I would say to create a batch file or edit the autoexec.bat file so that is loaded after dos did.

in the way of Boot managers use GAG visit here (http://gag.sourceforge.net/) the best thing about GAG is that it is free

1. Is it possible? - Yes

2. Would it work? - Only on separate primary partitions

3. What are the disadvantages? - Potential corruption of existing OS. Difficulty locating support and supporting information. Confusion because dual-boot and multiple boot are not the same. Not to be attempted without first backing up critical data.

4. What would be the best way to go about it? - Don't guess or listen to guesswork. Search and read first. At MS read Description of Supported Dual-Boot Configurations Between Windows-Based Operating Systems (http://support.microsoft.com/default.aspx?scid=kb;en-us;289283) and How to Multiple Boot Windows XP, Windows 2000, Windows NT, Windows 95, Windows 98, Windows Me, and MS-DOS

Is there a particular reason you need DOS 6.22?

You already have DOS 7.1 with 98se so it will be easier to just boot to DOS mode from 98.

Win 3.11 will install under DOS7, just make sure you choose something other than C:\WINDOWS.
