It integrates 7 * complete hardware monitoring features: voltage, fan and temperature 8 * sensors, and manual and automatic fan speed control. 9 * 10 * The F71872F/FG is almost the same, with two more voltages monitored, 11 * and 6 VID inputs. 12 * 13 * The F71806F/FG is essentially the same as the F71872F/FG. It even has 14 * the same chip ID, so the driver can't differentiate between. 15 * 16 * This program is free software; you can redistribute it and/or modify 17 * it under the terms of the GNU General Public License as published by 18 * the Free Software Foundation; either version 2 of the License, or 19 * (at your option) any later version. 20 * 21 * This program is distributed in the hope that it will be useful, 22 * but WITHOUT ANY WARRANTY; without even the implied warranty of 23 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
