Why have 2 OS on one machine?

I can undestand the useage of haveing a system with Windows/lynix on it, but why would you need to have a system with Win98 and Win2000? for that matter why even have one with 2 Win98's? on one HD? Does this speedup the computer?

To gain experience with differant OS's. As a student I would say this is useful.

2 OS or more on one machine does nothing to speed it up. Win9x has no built in security so NT/2k would be good for confidential files.
It is all about either security, learning the OS or both. Setting up 2 or more OS on one hard disk is a pain, but if you can do it, you have the savvy to get a nice job.

I do it to learn, without having to build extra machines. I know very little about NT and even less about Linux, but I am not gonna build myself three computers to use and swapping out hard drives is ok if you have them around.

Big words often hide small ideas.

I'm running a system with 5 OS's on it.
What's the question?

I think that having a multi-OS machine is nice for learning, but the only problem is that if one of OS's fries the Hard drive or you get a virus then it is more difficult to repair.
I am more for building seperate boxes and then having a mouse/keyboard/monitor switch on them and switch back and forth. I just built my first NT server. By the flick of a switch I was able to log onto the internet to find ways to trouble shoot my building of the NT and installations. It costs a bit more, takes up more space, and my wife wants to shoot me (having six computers networked in a three bedroom apartment gets to be a bit much for her) but I feel that in the long run I am getting a little bit more out of it, because I can see how the different systems interact with each other.
Getting 5 OS's on one machine I feel is more for bragging rights than anything else, even though you have an easier time with testing new hardware on the multiple OS's. https://forums.windrivers.com/images.../2000/09/1.gif
It really comes down to how much space and money are you willing to put into your system('s).

I want to thank all of you for your info, I guess that basicly its just a learning tool then to do a system that way. I my self find it easier to have seperate systems, for the different programs, the common joe, (who I will be able to help) isn't going to have 2,3 or even 5 OS on one unit. But thats cool i guess, more power to you all! LOL just seems like a bigger headache than the advanteges

I have 2 machines here , One for my everyday use and one for burning cds, network gaming and I plan on trying Win 2k on it since Win 2k pukes at my Intel based system , I will need 2 OSs on the other computer so I can learn Win 2k since I am a tech looking for work , and have Win 9x so I can burn a cd while I chat on my intel system
It would be cool to have a bunch of boxes on a shelf with a switch box for my mouse , keyboard and monitor
My room would look like the control room of the Nebucadnezzer from the movie Matrix
Now if only we had VR games like in that movie :>)

There are other reasons too. Different OS's have different abilities, you should pick the operating system that best fits your needs. Win9x is the best choice for Games. WinNT 4.0 and Win2000 are the choice for security and memory intensive apps such as 3D modeling and complex art work. Also if you have a high spec dual Processor system is would be somewhat wasted with just Win98.

There's probably more but I think that about covers it.
