I believe the file name is 1006dn0r.bio.

The latest revision for Orlando boards is 1012dn0r.bio. It's here: https://fr.pcdrivers.guru/multimedia-d142-dri … nload-4194.html

Also note that "Orlando" is a PB name for the Intel NV430VX. Possibly you can find more options under its original name. The "PB68x" stands for 682 (with S3 Trio) or 683 (with S3 Virge). Other than the video chip the two boards are identical. There are however multiple revisions with and without hardware MMX support (VRM to enable 2.8VCore) and with and without L2 cache. All share the same BIOS, hence the PB 68x BIOS.

Hillary is a different board, the PB620/30/50 (also Intel OEM board, never figured out exactly which) with i430NX chipset (and no MMX support other than overdrive regardless of revision)

Edit:
Nosing around in my old documentation, I have part numbers and max CPU per board. It's slightly more complicated as the early revisions with VRM can only supply enough current for a P200MMX and potentially burn out if you try 233MMX 😮

PB682 P200 non-MMX max:
185920100
185950000
6704710200
6708200000
6708200500

PB682 P200MMX max: (do NOT try 233MMX as you'll probably fry the VRM)
6708200200
6708200600
6708700100
6708840100
6709800000

PB682 P233MMX max:
6708200300
6708700200
6708710100
6708710300

PB683 P200 non-MMX max:
1814100100
1815930000-400

PB683 P200MMX max: (do NOT try 233MMX as you'll probably fry the VRM)
1816780400
678040000

PB683 P233MMX max:
1816780100

To figure out which you have, check the little white sticker on the motherboard. For this sort of question it really is useful to have access to the system in question...

Also mentioned in documentation:
- max HDD 13.6GB, no (official) upgrade for more space.

Sadly it seems that link gets a 502 when I try to download the file. Would this be available anywhere else?

Thank you for the all the info. I opened up the machine and the only small stickers I could find on the board did not contain any of those numbers. Here is are the only stickers I could find.
Yellowish sticker (possibly with age) has PSOR63903906
Whit sticker underneath that has - 181595 PB-SMT

I guess it is a good thing I didn't get to flashing BIOS or purchasing 233mhz CPUs hehehe.

I can just leave it the way it is since it is working. Figured I would do what I could to max it out. Maybe this is not the board I thought it was. The Orlando board was the only one I saw that looked similar.

Thanks.

Maybe take a good picture, then we can help/check.

Googling 181595 PB-SMT pulls up a pic on a Russian auction site of a PB682, so might still be an Orlando.

Where are you located? The P/N I posted are from EU PB models. Possibly US or other models had quite different P/N.

I can however confirm how to identify MMX support (if not whether 233MHz is safe). Take a look at these two pics, particularly at the location VM1C1, just under the CPU socket.

On this pic, it's unpopulated, so no 2.8V/MMX:

Also note the two empty rectangles where PLB cache could have been soldered.

On this one conversely, there's a VRM/MOSFET in there with a (weedy little) heatsink around it, so 2.8V/MMX support:

Here the two cache chip locations are populated, giving 256kB of L2 cache and a pretty significant performance boost.

So, check that location and you will at least know if it has any split-voltage/MMX support.

I have a suspicion regarding identifying the 233MHz version. On UKTSupport it says:

On later PB685 motherboards an enginering revision was made that removed pins 1 and 2 from jumper J1F2D.

Ignore the "685", that's an "MMX" indicator, just as the "680" is a non-MMX indicator, but the boards are still called 682 (Trio64) or 683 (Virge).

What this is saying is that the later revision doesn't have pins 1 and 2 anymore at J1F2D. I'd be willing to bet that that later revision is the one that can handle 233MHz, supported by the fact that a 3.5x multiplier setting is explicitly listed.

I definitely do not have that little metal heat sink next to the CPU, and I do not have the cache chips. So I would say certainly not 233mhz and perhaps not MMX. This MMX CPU seems to be running stable in it, but if you recommend I will certainly get it out of there..

Also, I am in the US, so that must be a US motherboard model number.
