hardware fixes (AMD K6, K6-2 and K6-III in Socket 7 boards by Elitegroup)

Elitegroup doesn't officialy provide support for K6 in old boards. But there are mainboards which can run the K6.
There is a list on Elitegroup's website to figure out correct settings:

P5-HX rev 1.0
No !

The board is missing the Voltage Regulator for Dual Voltage. If you look carefully at board layout there are pins to connect a VR. Anybody tried this ?

P5-TX-Bpro rev 2.x
Yes. Use at least BIOS version 2.2.
Set FSB to 66MHz and multiplicator to 2.0x.
Core frequency: Jumper J3: 1-2 & 11-12.
