Apparently it's explicitly controlled via SMBIOS. There's a SMAPI interface available from FreeBSD, but I don't have enough info yet to exploit it. Second question, still on power/clock issues, but diverging a little from ACPI: What's the interaction between SpeedStep clock and ACPI clock percentage? If I start on batteries, apparently the clock is at 600Mhz (even though dmesg reports it as 1600Mhz no matter what). ACPI CPU then can reduce this base by eighths? So if I start on AC, it's eighths of 1600 and DC, it's eighths of 600? Thanks again, Jeff Katcher __________________________________ Do you Yahoo!? Win a $20,000 Career Makeover at Yahoo!
