From 77a934a1eeadf53a0db0c332a55726859dcb413e Mon Sep 17 00:00:00 2001 From: njl Date: Sun, 10 Apr 2005 20:04:30 +0000 Subject: Set CPU speed to 100% in acpi_throttle attach. This is needed for some systems that boot with this value at the lowest setting. Change the default boot config back to "leave frequency as BIOS set it". Also, fix buglet where acpi_throttle wouldn't be used if p4tcc was present but disabled by the user.
