John Cagle said that there were 3 ways to control speedstep on the computer: Intel Speedstep applet, ACPI 2.0 PPC objects, BIOS. I tried a couple of things and then gave up. Linux's P-states and cpufreq on unpatched Kernel 2.6.4: acpi_processor_perf-0121 [320] acpi_processor_set_per: Transitioning from P0 to P1 acpi_processor_perf-0141 [320] acpi_processor_set_per: Writing 0x00000084 to port 0x00b2 acpi_processor_perf-0162 [320] acpi_processor_set_per: Looking for 0x00000001 from port 0x00b3 acpi_processor_perf-0185 [320] acpi_processor_set_per: Transition failed As an aside, I tried speedstep-detect but it doesn't recognise the chipset: marmite speedstep-detect-0.01 # ./speedstep-detect dmi_scan: return: DMI 2.3 present. 31 structures occupying 1210 bytes. DMI table at 0x000FD8F0. BIOS Vendor: Compaq BIOS Version: 68P4F Ver. F.18 BIOS Release: 12/09/2003 System Vendor: Compaq Product Name: Evo N610c (DJ121A#ABU) Version: Board Vendor: Compaq Board Name: 07F4 Board Version: KBC Version . Trying Intel's int15 GSIC: BIOS support GSIC call: signature: GSIC command port = 0x00b2 command = 0x0082 event port = 0x000100b3 flags = 0x07d00000 probing chipsets: No supported chipset found. lspci says that it is an 82845 Brookdale chipset. The southbridge appears to be an 82801CAM (ICH3) Has anyone had any success with this yet? I did scour the archive since that time but couldn't find anything pertinent.
