Wong 16 17Description 18----------- 19 20This driver implements support for the IDT ICS932S401 chip family. 21 22This chip has 4 clock outputs--a base clock for the CPU (which is likely 23multiplied to get the real CPU clock), a system clock, a PCI clock, a USB 24clock, and a reference clock. The driver reports selected and actual 25frequency. If spread spectrum mode is enabled, the driver also reports by what 26percent the clock signal is being spread, which should be between 0 and -0.5%. 27All frequencies are reported in KHz. 28 29The ICS932S401 monitors all inputs continuously. The driver will not read 30the registers more often than once every other second. 31 32Special Features 33---------------- 34 35The clocks could be reprogrammed to increase system speed. I will not help you 36do this, as you risk damaging your system!
