Hi Mark, I'm admittedly surprised by the dump, as all registers in the 0xF0-0xF7 range are set to 0xFF while the datasheet mentions default values of 0x00 for most. We might assume that the datasheet is wrong and continue, but this still worries me. isaset -y -f 0x2e 0x87 isaset -y -f 0x2e 0x87 isaset -y 0x2e 0x2f 0x07 8 isaset -y 0x2e 0x2f 0xf2 0xe7 isaset -y 0x2e 0x2f 0xf0 0xe7 At this point you can modprobe i2c-i801 if you didn't already. Then do "i2cdetect -l" to get the id of the i801 bus (most probably 0 or 1) and do "i2cdetect 0" or 1 or whatever number the i801 bus id is. See if any new device appeared especially in the 0x28-0x2f range. If nothing showed, try: isaset -y 0x2e 0x2f 0xf1 0xef And try i2cdetect again. If still nothing: isaset -y 0x2e 0x2f 0xf1 0xf7 And try i2cdetect again. If still nothing: isaset -y 0x2e 0x2f 0xf1 0xe7 And i2cdetect again. If still nothing we have lost :( so let's just hope that one of the i2cdetect above found something. Finally release the super-io chip with: isaset -y -f 0x2e 0xaa Thanks, -- Jean Delvare
