Set custom cpu fan speeds

[moonlightz]

Hi there,
I seek some help odding the BIOS of a ASRock Conroe945G-DVI.
Asrock seems to have thrown out their support for bios and other software. I maybe wrong. I had to dig the net for the P2.00 version to flash from DOS, it was quite hard and I eventually found it from driverscolletion site.
I noticed the DOS flasher is a single exe and I'm unable to unpack with 7zip.
Luckily, I got a TL866II-plus and I had a hard time to remove the plcc32 chip that was socketed because it was near some caps and the tool couldn't reach down below the chip.
I read the plcc32 chip, winbond w39v040fb and got the rom image out the chip. The tl866ii-plus software was being stubborn and wanted to be updated to 11.81. Still the horrible English translation there...
Ok, my idea now is to set custom cpu fan speeds for the current 3 settings FAST/MIDDLE/SLOW under Quiet Fan. I have now set to SLOW but... the fan is just noisy still. I would like to mod the PWM or whatever values or remove all and set for example 9 speeds.
I have mmtool 3.26. Someone could help? please and thanks
