Hello everyone! I’m not a native english speaker. sorry for my languages
my system is Compal QAL51. It is quite old laptop so I’m planning to upgrade cpu from 3230m to 3720qm or 3920xm
why 3720qm or 3920xm is that
bios feature is all locked even fan control except for only boot menu 3920xm has unlocked multiplier but if I can’t set multiplier in bios, 3920xm will be useless
and I want to set manually fan speed. If I could
I tried to mod bios myself with H2OUVE tool but H2OUVE crashed when I clicked the setup menu
I also tried IFR Extractor, I didn’t get any meaningful values
bios is consist of QALXX640.bin(6MB) and K5FE640A.ROM(128kb) I think .bin (6MB) is main file I don’t know what .rom(128kb) file is I attached whole bios files and tools just in case
Hi! Thanks for sharing. The ".rom" file is EC (Embedded Controller) image for your device.
Sadly, this is the only wish I can satisfy. There is no processor multiplier control in your BIOS. After installing my mod, the fan settings should be located under the path "Chipset - Thermal Configuration - Platform Thermal Configuration".
Oh! Now I see. The manufacturer has defined TC in a separate tab, thereby blocking access to the settings, because now nothing refers to them. I don’t think I should continue modifying this bios. Thanks for feedback!
Yes! I roughly imagined your BIOS setup, but it looks like a lot still remains inaccessible. I don’t know why all this is there, even if the manufacturer cannot have access!? I say this because the only way to unlock I see the cut and paste method.
I still don’t know how everything is in reality, because I don’t have bios pictures. I could have continued that way - IFRExractor can still process my modified modules without errors. But, nevertheless, I cannot be completely sure that my work is not useless. You need to do tests. However, I can't see the overclocking menus. Second BIOS mod is available: Compal QAL51.zip.

Do not touch this line and two lines above, This GOPs for your internal HD4000 (in CPU). You must find GOP for GT640. And, of course, you must have CH341 programmer for come back.
And I forgot ask you, how booting notebook, CSM or UEFI mode?
In UEFI mode.
I was able to edit the bios and enable the internal graphics.
When I leave it enabled, it only shows the image in the BIOS, but it doesn’t show the OS boot. I think it’s a motherboard limitation.
