I'll disappear quietly if someone gan help me ;-). I have a Biostar K8NBD-S9 motherboard with the IT8712F super i/o chip. The board suffers from the buggy BIOS which causes the manual PWM feature of the chip to be unreliable to initialize. After much googling I found this thread which indicates that Jonas Munsin and Jean Delvare were working on a workaround for this back in January: http://lkml.org/lkml/2005/1/14/94 The thread also suggests that the patch was destined for the -mm tree. I have looked as well as I can at the 2.6.14 -mm patches, but can't see any reference to it87. Currently running 2.6.13 vanilla (with some patches). The it87 driver seems to implement the bug testing function which Jonas and Jean were talking about in the 2.6.10 /2.6.11 days, but doesn't conatin any workaround beyond disabling PWM once the problem is identified. Can anyone tell me if a patch against 2.6.13 exists (or whether it is implemented in some flavour of 2.6.13 / 2.6.14), or how possibly to customize my own module code to initialize pwm for my board (this will be a htpc frontend box so I really need the quietness)? Many thanks Marius Schrecker
