BTW: The value invalid shows when it is unplugged, wouldn't value "0 RPM" make more sense in that case? At least that's what BIOS reports for unplugged fans.

Here it is the output (as decimal): Oct 20 14:08:04 chinatsu kernel: it0 at port 0xa30-0xa37 on isa0 Oct 20 14:08:04 chinatsu kernel: it0: ITD_COREID = 18 As for using Linux CD I can't do it immediatelly, the box does not have cdrom, besides I don't have any image lying around. Any recommendation for something that I could boot from USB and would be able to provide everything you need? -- Best regards, Derek mailto:takeda@takeda.tk The meta-Turing test counts a thing as intelligent if it seeks to apply Turing tests to objects of its own creation.
