Preloading certain frames

hello all,

i have my portfolio website which is a 1.5mb big flash presentation and i thought about making a preloader.
the problem is that making a preloader for the entire site will take too long to load. i have tried that.
so i thought about making a preloader for each “page” or section of my presentation. for example- just for syneron, or just for m-systems (with each of them have a few different pages in the presentation, but their size is manageable).

the problem is that i cant find anything is the preloader code that will let met control what frames to preload (for example, frames 100-200).

i have to tell you guys in advance that i don’t know anything about html,js or likewise. all i know is some flash and dreamweaver i learned myself to put up this site.

thanks in advance,
