| 12 | Description | ||
| 13 | ----------- | ||
| 14 | |||
| 15 | This driver implements support for the IDT ICS932S401 chip family. | ||
| 16 | |||
| 17 | This chip has 4 clock outputs--a base clock for the CPU (which is likely | ||
| 18 | multiplied to get the real CPU clock), a system clock, a PCI clock, a USB | ||
| 19 | clock, and a reference clock. The driver reports selected and actual | ||
| 20 | frequency. If spread spectrum mode is enabled, the driver also reports by what | ||
| 21 | percent the clock signal is being spread, which should be between 0 and -0.5%. | ||
| 22 | All frequencies are reported in KHz. | ||
| 23 | |||
| 24 | The ICS932S401 monitors all inputs continuously. The driver will not read | ||
| 25 | the registers more often than once every other second. | ||
| 26 | |||
| 27 | Special Features | ||
| 28 | ---------------- | ||
| 29 | |||
| 30 | The clocks could be reprogrammed to increase system speed. I will not help you | ||
| 31 | do this, as you risk damaging your system! | ||
