Hoffman <mhoffman@lightlink.com> - -Description ------------ - -This driver implements support for the Asus ASB100 and ASB100-A "Bach". -These are custom ASICs available only on Asus mainboards. Asus refuses to -supply a datasheet for these chips. Thanks go to many people who helped -investigate their hardware, including: - -Vitaly V. Bursov -Alexander van Kaam (author of MBM for Windows) -Bertrik Sikken - -The ASB100 implements seven voltage sensors, three fan rotation speed -sensors, four temperature sensors, VID lines and alarms. In addition to -these, the ASB100-A also implements a single PWM controller for fans 2 and -3 (i.e. one setting controls both.) If you have a plain ASB100, the PWM -controller will simply not work (or maybe it will for you... it doesn't for -me). - -Temperatures are measured and reported in degrees Celsius. - -Fan speeds are reported in RPM (rotations per minute). An alarm is -triggered if the rotation speed has dropped below a programmable limit. - -Voltage sensors (also known as IN sensors) report values in volts. - -The VID lines encode the core voltage value: the voltage level your -processor should work with. This is hardcoded by the mainboard and/or -processor itself. It is a value in volts. - -Alarms: (TODO question marks indicate may or may not work) - -0x0001 => in0 (?) -0x0002 => in1 (?) -0x0004 => in2 -0x0008 => in3 -0x0010 => temp1 (1) -0x0020 => temp2 -0x0040 => fan1 -0x0080 => fan2 -0x0100 => in4 -0x0200 => in5 (?)
