Both registers (0x0a of the HWM logical device I/O area, and 0xfc of the Super-I/O config area) agree on the value (6 LSB = 0x3f, which translates to 0.000 V). The high bits of register 0xfc say that this VID value is the "initial" value and not the "current" value. You may try writing 0x01 or 0x40 to this register to update the VID value, in case it changes anything: isaset -y -f 0x2e 0x87 isaset -y -f 0x2e 0x01 isaset -y -f 0x2e 0x55 isaset -y -f 0x2e 0x55 isaset -y 0x2e 0x2f 0x07 7 isaset -y 0x2e 0x2f 0xfc 0x01 # or 0x40 isaset -y 0x2e 0x2f 0x02 0x02 isadump -k 0x87,0x01,0x55,0x55 0x2e 0x2f 7 If this doesn't help, possibilities are: * The CPU VID pins are not connected. * The CPU VID pins are connected, but the VID_ISEL value isn't correct for your CPU. That would happen if the pin 5 (JP6) wasn't wired properly. In both cases, this is a hardware problem, which can't be worked around in software. -- Jean Delvare
