Ok, i got a P3 with 64Mb ram in it, suggest me a light linux distribution for it, the one and the only application i need to run on it will be mozilla Firefox, nothing else in this world will that comp be doing, so if there's anything like an bootable OS that can run firefox or a bootable firefox, good for me, hope this explains what i require, suggestions please.

Try Damn Small Linux!

Since you're using Slackware already and are no doubt familiar with it, you could do a minimal install of Slackware using manual package selection. Install a fast, light windows manager like IceWm or, if you prefer, a light desktop environment such as Fluxbox. Your box will easily handle this. The trouble with live distros is that they are already slower and may seem to crawl along on that box, mainly due to the lack of RAM rather than the P3.

One observation I might make: a lot of content on the Web these days requires reasonable multimedia capability. Your old box may struggle with this no matter what OS you use.

i think i will give it a try, but since i am new to linux, i might not be able to figure out what are necessary packages and what are not, anyhow even if it does not work, no harm done, it is just an extra machine and i can start over again, another thing is, will it ask me to install KDE, because i dont want to install KDE at all.

You don't have to run KDE if you don't want to. The problem for you is that Firefox will be quite slow in 64 MB of RAM. Is there any way you can upgrade (cheap RAM of eBay?). Even bumping up to 128 MB (or bettern yet 256) will make Firefox a lot more responsive. There are lighter weight browsers such as Dillo, but they have fewet features. Opera might run a bit lighter too.

it is actually not my PC, they belong to the computer lab of my hostel, and i am the admin, there are only 2-3 such PC's lying around, i though may be i will put them to some use, so u see i cannot change config,

furthermore, if KDE is there, people will run KDE, becuase they dont understand what is good and what is not, so i need to stop them from running it, i can remove it later, but i dont want it to be there in the first place.

you have all the "right answers" already.
If your HD is at least 1 GB you can try vector linux
If not found of DSL you can try puppy

Anyway, just note that this type of question are best suited

I like xfce4 windown manager for my light versions, loads extremely quick, usually a thrid of the time kde or gnome take to load.
