There are several others, but see man acpi_ibm for some impressions. Yes, but I have an acer Aspire 5634WLMi, and: % ls /boot/kernel/acpi* /boot/kernel/acpi_asus.ko /boot/kernel/acpi_panasonic.ko /boot/kernel/acpi_asus.ko.symbols /boot/kernel/acpi_panasonic.ko.symbols /boot/kernel/acpi_dock.ko /boot/kernel/acpi_sony.ko /boot/kernel/acpi_dock.ko.symbols /boot/kernel/acpi_sony.ko.symbols /boot/kernel/acpi_fujitsu.ko/boot/kernel/acpi_toshiba.ko /boot/kernel/acpi_fujitsu.ko.symbols /boot/kernel/acpi_toshiba.ko.symbols /boot/kernel/acpi_hp.ko /boot/kernel/acpi_video.ko /boot/kernel/acpi_hp.ko.symbols /boot/kernel/acpi_video.ko.symbols /boot/kernel/acpi_ibm.ko/boot/kernel/acpi_wmi.ko /boot/kernel/acpi_ibm.ko.symbols/boot/kernel/acpi_wmi.ko.symbols I don't have an acer kernel module for ACPI. Two options: If you can derive from the documentation of your Acer laotop if it is _compatible_ to one of the implementations provided by the system, use that instead. You can do trial error to see if one of the modules works, even though the name is different. In worst case, load them all (by using * wildcard) and check with kldstat. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Why ? Because, my BIOS don't support these aparameters ? Another answer ? acpi_ibm(4) is a kernel module that isn't loaded by default. Depending on your hardware you may have to kldload a different module. You could try: ls /boot/kernel/acpi_*.ko and then kldload the module you think makes sense for your hardware. Note that not all modules have fan control, though. As I only use IBM and Lenovo laptops I'm not familiar with the other modules. Fabian signature.asc Description: PGP signature
