Still need an original bios or it'll say "no input file found" ;P
I tried to put a fake bios file there but it looked like it was gonna flash then the program crashed

All,

I'm recently returned from a deployment in Afghanistan. Due to the super-slow personal internet connections there (5-15kbps), I was unable to upload modded BIOSes (connection would time out long before upload completed), so I stopped following this thread. I'm back now, and though I don't plan on spending as much time doing this as I used to, you can send me any outstanding requests or questions and I'll try to get to them when I can.

As for the non-OC 13.5 BIOS: 1645_A13W2_No_OC.zip

Edit: and this one requested 2 pages ago: 1645_A13W2_4670_750_900.zip

Hey, seeker_moc, can you please re-upload the 1645_A13.5W_4670_ 810_970.zip file? The link does not work..

Hi, does anyone know if the 1645_A13.5W_No_OC.zip BIOS makes it possible to control the fan speed in Linux. I want to try and make the system more quiet.

Thanks,

You can adjust the Fan low/fan high trip points in the modded BIOS. In Linux, the changes to the BIOS are correctly reflected in /dev/proc/(acpi trip points? I forget the name of the file, I'm not on a Linux machine right now).

However, IIRC, the fan behavior does not actually change in practice. I beleive it was Kizwan and a few other who think that the fan speed is directly controlled by the laptop embedded controller, and any BIOS settings are bypassed (look back through older posts in this thread for more info). You'd have to find a way to modify the embedded controller instead. There is a lot of information on how to do that on Google if you search, I haven't gotten around to messing with it myself yet.

bump is anyone still active, to modify the BIOS to allow CPU overclocking?

As far as I know there's no way to do it through the BIOS. All examples I've seen of OCing the i7 CPU in laptops have been through OCing the PLL. Last time I looked, the PLL in the 1645 is not supported by any of the common PLL OCing tools (thogh I haven't looked in over a year). Try looking for one of the programs and trying it out. If not you'd have to figure out which PLL our laptop uses, and contact the developer of the tool and ask him to add support for ours. There was a discussion on this back earlier in this thread as well.

I really wish my I could OC this i7.. In some games i'm totally bottlenecked because its running @ only 1.8ghz

I have the same driver but it works fine for me.. There is a new update for for the 4670, 12.4, maybe that would solve your problem..

I'm on 12.3 and no problems
