BiosConfigUtility for Linux ?

Alfred Biwer_1 — Wed, 28 Oct 2009 12:09:25 GMT

I look for a solution to change the bios settings under Linux (on xw8600, z400, z800).

Is there something like BiosConfigUtility for Linux ?

Anyone, already do this ? Or have another way to do this ?

Thanks

Shalom,

Bios utilities are built into the hardware. You boot the box and hit a function key to get in to that functionality.

Hi,

depending on what you want to do, you can use tools like http://www.flashrom.org/Flashrom or

http://www.pixelbeat.org/docs/bios.

If you are not confident, I would avoid using these utilities. Also, most changes you make would require you to reboot anyway, so not sure what you are trying to acheive.

Hello Steven, hello Matt,

thanks for the answers.

No, I don't want to flash the BIOS eprom.
I want to be able to determine, if possible change the state of BIOS settings like 'OS power management' out of a running (Linux-) system.

Regards,
Alfred

This depends on the actual settings you wish to manipulate.

For example, "OS Power Management" would be a *very* BIOS manufacturer-specific setting.

On the other hand, if you can successfully use ACPI in Linux, the setting is either already enabled, or it is overrideable by the OS *and* Linux has already overridden it.

Look into /proc/acpi: do you see ACPI information in there?
