Question do i have to tell linux i changed the amount of ram?

i just installed FC2 and know i will be changing the amount of RAM. right now I have 192 meg total: 3 64 meg modules @ pc100 and pc133 and plan on swapping them out for just one 128 meg pc133 module.

do I need to find a setting somewhere to tell the os how much memory i have? and if so how do I do that?

Linux should autodetect this and you shouldn't have to worry about it.

I'm sure the first install created a swap partition that was set for 192MB, so it should be fine for 128MB.

That 2-3x was the old rule of thumb... I have 256MB of RAM on my laptop, and don't remember the last time it had to swap anything. The new rule is don't waste space for swap you'll never touch. Unless you are dealing with many simultaneous users, or huge multimedia file editting, 128MB of swap is more than enough for regular use nowadays.

It does depend on what you're doing, but as a desktop use who occasionally plays UT etc, I never touch my swap with 640M physical memory - I'm sure swap would be useful if I was Photoshoping or something like that, but my 1GB swap partition is just being wasted :(
