Everything seems to work ok though. google? :) anyway: /usr/src/sys/i386/conf $ less NOTES [....] # # Set the number of PV entries per process.

How do I configure the system to boot without APCI > automatically? (FAQ) /boot/device.hints, change the following lines to ### APM vs ACPI hint.apm.0.disabled="0" hint.acpi.0.disabled="1" /boot/loader.conf.local: apm_load="YES" (that's to enable APM instead of ACPI - if not a laptop, u can have both off). ACPI shouldn't be compiled into the kernel, of coure. good luck, Beto
