Tualatin PIII-M upgrade

OK, I have this old notebook (Compaq Evo n600C) and I want to upgrade it as much as I can (within reason).
The memory and hard drive components are easy to deal with, but the chip...
I researched Pentium III's and their core names and blah blah blah. But no where on Intel's site or other guides across the net can I find a Mobile Tualatin core with an 866MHz clock speed. Strange.

So my question is, what's the fastest chip that I can just drop in here? And will it only need bios support?

370-pin 1.4GHz Tualatin? But these do not specifically say Mobile PIII, they say Celeron or something else.
Any help is appreciated!

also if anyone knows how to switch out an AGP4x graphics card for a notebook. :]

 

Seriously man you would be better off just getting a new notebook. If your willing to replace your hard drive and loose all your stuff, you mind as well get a whole new system. That thing is so old and slow I dont see how you can use it.

You can get a good new notebook from dell for like $600, which is dirt cheap as far as notebooks. Yeah it might be more expensive then upgrading that thing if you even can, but it would be more economical and smarter in the long run. Good luck with what you decide.

 

The Evo is just some notebook lying around here. I'm waiting for a Merom-based M90, but I just felt like upgrading this old junk that I acquired for free for basic-documenting tasks for when my huge m90 is, well, too huge.

There's nothing on the drive, it would be nothing to just tinker around with. I would just like upgrade the cpu ($30 tops) and put some more memory in it. That way it's "usable".
