AMD K6-2+ compatible with my board?

Me once again! So I've now picked up a K6-2+ 550 for my Super Socket 7 Slim build to complement the Voodoo 3 3000. After checking the mobo compatibility. It's based on SiS 530 chipset and here's a link to the exact model:

Also I did make sure to update to the newest firmware before swapping the CPUs as it's happily running a K6-2 @ 500 MHz, although I experienced instability when attempting to push to 550 MHz using the 5.5x multiplier. It will post but Windows won't load, even just in safe mode.
[Posting and working fine at 500 MHz (5x100) using standard K6-2]()
In short I've tried both 2.0/2.2V for the 2+ and was only able to get it to post on a 3x multiplier using 100 MHz FSB (no luck with 5.5x, 5x, 4.5x or even 4x). However even with that it was unable to ID the CPU on the post screen and claimed it was running at 66 MHz.
Can I check if anyone on here has had luck running a K6-2+ with this board? Or is there another jumper setting I haven't accounted for? Any advice would be greatly appreciated. Thanks!

UPDATE - we're all sorted now folks. Please see the original post for the full solution. Thanks again!

My understanding is that the mobile editions (with the plus and lower Vcore) usually needed a supporting BIOS.

I'm intrigued and just did a little bit of research. Since they were mobile chips you definitely shouldn't need to overvolt, I think they're designed for 2v
There was some talk about custom BIOS being made for some boards to accommodate mobile chips, so maybe look down that avenue? You might find some on retroweb

There's really not much to the jumpers outside of voltage, FSB, and multipliers.
The chipset can handle the K6-2+ at that speed (I have a similar board with the same chipset and a 550 2+ that works) and your board seems fine as it works correctly with the 500.
It's possible that the CPU itself is DOA, are you able to get a replacement? I doubt that they're actually 'tested'. The fact that it doesn't run well at all leads me to believe this, as the 2+ should be able to run even as a "K6-2 550" even if the BIOS doesn't have explicit support for it.
