Hi,

I need to be able to slow down the STPC Atlas clock to save power under Linux. Is it possible to use the CPU frequency scaling feature from 2.6.x kernels to do that, i.e., is there any CPUFreq driver available for the STPC Atlas? If not, is there another way to accomplish that?

Thanks,

First of all you have to check if the BIOS supports the SMI routine, if not you can't enter in sleep mode cause the APM of the STPC is not Standard. So you have to write the SMI routinr by yourself so Write a BIOS and in this you can have the Bios Writer's guide as reference, or to contact STPC support team and they will provide you a GSW Bios which support the ST SMI routine.

Thanks.
