hardware fixes (AMD K6, K6-2 and K6-III in Socket 7 boards
Chaintech doesn't officialy provide support for K6 in old boards. But there are mainboards which can run the K6.
2.09V=2.8V+2.9V (best for 2.2V K6)
Highest multiplicator on this board is 3 as BF2 is not connected on this board.
You have to get pin W35 (BF2) grounded. Just connect it to V36 (Vss [ground]). Now the multiplicators are raised (1.5=4.0, 2.0=4.5, 2.5=5.0, 3.0=5.5).
CPU is recognized as 486DX.
