I've got an old laptop that uses a desktop Pentium 200 mmx. It's currently running Linux pretty well but I'd like to know what's the fastest Intel or AMD chip I could in the socket to replace it.
what socket did the Pentium 200 MMX use and what is the fasted CPU I could use to replace it?

Pentium 233
It was called a Socket 7
The super7 platform took over it and added the 100mhz FSB. These boards could take AMD K6 -2processors up to 550 mhz

The fastest Pentium Classic is 200MHz. There is no P54C 233MHz.
The fastest Pentium MMX is 233MHz.
They use Socket 7.
You should be able to drop in an AMD K6-2 300MHz (at the very least), and perhaps go all way the to K6-2 400 or K6-3 and even higher.

The processors in laptops are usually soldered in, and can't be replaced.
In the last year or so, some of the mobile PIII-m have been socketed and can be upgraded.

Hey, that's sweet. I never knew you could stick a K6-2 chip on a Pentium MMX board. I've got an old P233MMX computer laying around that I'm about to give my sisters, I may stick a K6-2 chip in there. Btw, would the stock HSF that's on the P233 be sufficient for a K6-2, or what sort of HSF would I need? The board I've got doesn't support overclocking, so that's not an issue (I've got 3 old machines laying around and none of them support OC'ing and two of 'em have gigabyte boards, too).
powerleap made these voltage regulator and other things so that you can use a AMD K62/K63 processor with your pentium mobo.
Ok -
Assuming that you're correct, and it's a 'DESKTOP' P55C chip, there's still a few issues.
I've seen a few laptops with desktop chips, but most of them were socket 370. The s370 chips aren't exactly the same as their desktop cousins, as they use slightly lower voltages. (the p3-800 I have in front of me does, anyway.)
The Multiplier issue - the board in the laptop was likely only designed with the intel chips in mind - as it's all the manufacturer was ever going to use in them.
This is whats LIKELY, not gospel obviously
Because of that, you're lucky if it has over 3x support - very few pre-'super' socket-7 boards supported 3.5x - let alone the ~4x that a K6-II or similar will require.
So even a 233mmx could be some hassle.
BIOS support - if the laptop board is based on an Intel chipset - you can pretty much forget using an AMD replacement. There's a chance it'll work - but last time I tried putting a K6-II 266 into an intel VX-board, it saw it as (I kid you not) a Cyrix 486 - and refused to get past POST.
A BIOS update would most likely fix that - but can you find one new enough for that board? Probably unlikely, i'd say.
Voltages again - i'd be really shocked if you even had a jumper to alter the voltage on a laptop board - so whatever chip you use - it'd wanna be matching voltage.
Use a chip thats rated too low and of course if you dont kill it - it's not going to be a 'lap'top anymore

Are there any S7 boards that allow you to just pull out a P233MMX and stick in a K6-2 (with maybe a BIOS flash) or do they all require an adapter of some sort?
Ok, I've done some research, and have found out that there are, in fact boards that don't require an adapter in order to run a K6-2 or higher chip. In fact, it looks like I may even have one. Here's what I've found out so far:
The motherboard is a GA-586TX2 with the i430TX chipset.
It supports voltages from 2.0-3.5v in 0.1 increments via jumper setting.
It has multipliers from 1.5 up to 5.5 via jumper setting with either 60 or 66MHz FSB
It supports at least a K6-233.
According to this page at gigabyte, if the PCB revision is 2.13 or higher, it will support at least a K6-2 400
Its voltage-compatible with up to a K6-3+.
Unfortunately, I have absolutely no idea which PCB revision I have, as it doesn't seem to be printed on the board anywhere and I don't know how to find out. If any of you have any other useful information or tips that would help me figure out what I can stick in this thing, I'd appreciate it.

Have a look at the top RH corner of the mobo. I have a 586TX3, that's where its rev. # is. Maybe it's the same on yours.
Realistically, the fastest you can go is 400MHz, set your voltage to 2.2v, multiplier to 2x, using a K6-2/400, it remaps the multiplier to 6x, giving you 400. You can use any K6-2/400 or faster, they all have the multiplier remap. But you'll top out at 400MHz because of the 66 bus limitation.
Really, you can stick a K6-2/400 in almost any S7 mobo that does MMX...the newer revision of your mobo prolly has more capacity in the VRE, the 400 might pull too much juice for the earlier rev, maybe shortening your mobo's life.

Thanks for the info, I'll check that out.
[EDIT: Unfortunately, its only a REV 2.03, not 2.13, so I don't know if it will take a K6-2 400 or not.]

Guys, I'm currently running a FIC VA503+ rev 1.2a mobo and a AMD K6-III 450+ O/C to 550 mhz, w/Win ME, 256mb PC100 ram and all the modern stuff (USB, Firewire, CDRW, etc). FSB is 100. Been running it this way for over 2 years with narry a problem. FIC motherboards like mine have lots of options. Originally, I started out with a 233 and 32mb ram and kept upgrading from there. Pretty good upgrade path, huh?
If you go do a google search, there is a FIC newsgroup for this mobo and they can tell you what you need if you want to run a similar setup.
Sadly, I just built a 2.53G computer w/1gig of ram. So I'm going to have to give my "baby" up. Oh well...

I've decided to try e-mailing Gigabyte in the hopes that they can tell me what the 2.03 revision of my motherboard can run, but their website seems broken. Does anybody know their support e-mail address?

I bet it will run the K6-2/400, just not 'recommended'

Thanks for the link. For some reason in Mozilla and IE the best I can get is a "Server Not Found" or "Page Not Found", but I managed to get it working enough in Opera to find the tech support e-mail page. I have to say I'm a bit impressed as to the level of support they still provide for their old boards.
I e-mailed Gigabyte tech support, and apparantly replying to guys who ask about 5 year old motherboards isn't high on their list of things to do. Oh well.
IIRC there is actually a Slot-1 -> Socket 7 adapter made that might allow you to put a Pentium III in there (provided the surrounding area in your case isn't too cramped).
Intel went to slotted CPUs saying that the old Socket 7 form factor had reached its limit so someone made an adapter just to prove em wrong.
Note that most of the Slotket stuff is for Socket 370 not Socket 7 so you have to check carefully.

*starts dreaming up evil plans of sticking in a Socket 7 -> Slot 1 adapter, then sticking a Slot 1 -> Socket 370 converter on that and running a 1.2GHz CPU on my 6 year old Socket 7 motherboard!* BWAHAHAHAHAH!!!
The best part is a Super7 motherboard would actually make the fastest PIII motherboard around, with typically 512K (sometimes 1M) of L3 cache (intended as L2 for most socket 7 chips but...)
