There's been a lot going on around here, so sorry for the delay. I looked at the datasheet to see how pin 58 is configured. SI (serial flash input) and AUXFANIN1 are affected by two registers: 1. register 47h: force AUXFANIN1 to act as a fan output 2. CR[0x24] bit 1. ENROM. The datasheet says a hardware reset is necessary. My guess is that the serial flash interface is set by default. I think there's a way to reset the w83627ehf chip by writing to certain ports. What do you think, Jean? David P.S. Working on an updated w83627dhg patch!
