I have a "heads up" and a question.
-----
First, the heads up: a motherboard I got from a computer show many years ago stated that Alton was the maker. Using this info and the easily readable TXpro chipset, many if not all sources claimed it to be the PCChips M575 (like
http://www.plasma-online.de ). Without real close inspection, it was easy to believe it.
I don't know if the vendor had it in the wrong box (he didn't have any reason to be shady... I was and still am somehat ignorant of motherboard details

but hopefully this is changing). After buying a CPU, resistors to mod the board and bothering BiosMan for the patched beta BIOS, I blew the dust off of it and learned it is indeed an M560.
The moral of the story: if you have an Alton motherboard...
really check what you have before proceeding with any tweaking or upgrades. There are MANY similarities between these older pcchips boards and it can be easy to confuse them.
BTW - Jan's patched BIOS for the M575 even worked on this board

. It's up and running Linux, though, I doubt a 2.0v K6-II+ is going to survive in a 2.5v socket. Maybe a MB mod down to 2.2v and some overclocking will do the trick... but I'm skeptical.
-----
Now the question:
I see there is a patched BIOS for the M590 in need of testers. This motherboard doesn't seem to have vcore jumpers (like the modifiable boards such as M571) so I'm curious if the patched BIOS will work with a 2.0v K6+.
For that matter, do ALL K6+ CPUs have 2.0v cores?
I'm asking because I've already got the 2.0v K6+ CPU (plus a new soldering iron with resistors

) and an M590 is available on ebay at the moment. I see that Xiaonian claims the K6+ CPUs will NOT work in these boards... which I would tend to agree with offhand. BUT if this is the case, how can there be a patched BIOS in testing which supports K6+ on these boards?
Thanks
ps - I know I could just get a MB which supports a K6+, but this is a 2nd computer and I don't mind getting a specific motherboard to advance the cause here.
