Where do you think XP is loaded normally?

Other than that, you can't disable the swap file without some problems.

When I frequented the windows forums, there was a guy who claimed to have set it up so on startup, the os was copied to a RAM drive and he claimed to run it completely from RAM. It was in the win9x forums, and after some searching I found it here. I stand by what I said...BAD IDEA, but full points for creativity. This is making OS programmers all over the world shake their heads at the futility of their jobs:-)

If you get it working, please post back. This subject is fascinating.

A fairly technical delusion. Win98 will not allow you to map a section of memory into a drive. Partly Windows doesn't simply automatically format a section of RAM with a filesystem. I thought there was a version of Windows (maybe 98) someone had compressed and made into a live-boot setup (similar to Knoppix). I will have to look for that.

In case anyone is wondering, your OS is loaded into your memory (RAM) on boot up.

Someone told me that if I turned off the swap file (or maybe it was turn it on, can't remember) you could force windows to boot completely into RAM and it would run much faster..

not completely sure

We'll start out with a simplified explanation of what the swap file is...It's where windows stores stuff when it runs out of room. You have so many programs running that your 512 MB of RAM can't hold it all, so windows creates a "swap file" on your hard drive that pretends its RAM. This makes things run slower, because your HD if much slower than your RAM.

You can probably already see the problems with turning off the swap file...What does windows do when it runs out of RAM if there's no where else to go? Crashes. Badly. No time to save your work, no time to shut down.

Secondly, windows doesn't want to use a swap file any more than you do, and it only does it when necessary. Turning it off is just tying its hands.

Some programs do not run and give you a low memory warning. I have not observed any more severe consequences.
