I thought the CPU fan starting wasn't under BIOS or any other control on a regular main board. Laptops have their own peculiarities, so I'm ignoring them. Starting a box results in the fan spinning up almost instantly, even before I get a BIOS signature displayed on the monitor. We may be able to monitor CPU and other fan speeds, but is there an actual control mechanism to turn it on or off? If so, what API or control point provides such access? -- Bill Gradwohl YCC (817) 224-9400 x211 www.ycc.com SPAMstomper Protected E-mail www.stomperware.com
