In my opinion, if the motherboard has switching (and non-linear) voltage regulators, you can safely try, starting with low FSB, so I would try 50X6=300, then raise to 360, and hopefully (no weird errors ), you can easily go up to both 400 and 450 (if you want more speed), if you want you can even go up to 500, but at that frequency the PCi would go above 40MHz, and this could create some problems for the disks.
Personally I have installed several in both VX and TX, but if you have a motherboard with linear regulators, as the frequency rises the VRM heatsinks could get red-hot, with those motherboards it's better to stay below 266-300MHz, but still if you use a good heat sink with fan (for CPU), I think for example one for 370-462, you could feel more relaxed, it should keep the CPU cool, especially if you have the first pentium one, with fins less than a centimeter high, in that case I recommend to switch to a more efficient one.

I'll be using a socket 462 cooler, picture related.
That silver metal plate is for socket 754 I believe, but on sockets 370 and 462, the black retention module on the right is clipped onto the "noses" of the socket, which appear to be the same or mostly the same on sockets 370 and 462. The cooler itself is then simply screwed onto the retention module.
The fan should cool the surrounding area a little, so I was planning to add some heatsinks on the VRMs, probably with thermal adhesive tape, since that's easy and probably a lot better than not having heatsinks on them.

Surely that heat sink, if you manage to hook it, will keep the CPU cool, being large it could touch somewhere (capacitors near the CPU), but if it fits without too many problems, I imagine it will be more than adequate, and should keep very cool processor.
Here : if you are interested you can find the models of many motherboards with BIOS adapted for the K6+, your HX does not seem to be there, but if you want (or need) a modified BIOS you can see if there is the possibility of obtaining it , depends on whether whoever makes them is willing to make you one.

Hi, I was wondering if it's possible to get my AMD K6-2 500 AFT to work on my Gigabyte GA-586HX Rev. 2.01. Not at 500 MHz, of course.

But the board does support an FSB of 66 MHz, and the CPU interprets a multiplier of 2 as 6, which should result in 66x6 = 396 MHz clockrate.
The Revision 2.01 also has a series of dip switches that let me control the CPU voltage from 2.0 to 2.7V in .1V steps, so that shouldn't be a problem either.

Am I missing anyhing?

I'm a little scared of frying something, so I thought I'd ask around before actually attempting it. And since the board itself is somewhat popular, I'm sure there's somebody here with a little more experience on this.
Better safe than sorry.

Install the latest bios update. other than that yeah, no problem go for it

I advise against using a socket 462 cooler they have way too much pressure on the clip maybreak your socket.

A celleron or socket seven cooler is more than adequate for these rather cool CPUs
