Hi Maco, I know what is flash a bios,but

Hi Maco,
I know what is flash a bios,but normally the bios is unloaded and put in a external socket,the same circuit can be used to program an external bios 8 pin chip, but searching on web how to do, they say flash the bios in the matherboard by SPI using an external pc w parallel.
They was clear, no voltage on the matherboard and no 3Vcc battery on.
and so i did, but i lose 1 day and in the end worked only putting the 3V battery in the matherboard.
I don't have any linear scheme of the matherboard, I'm a little myopic, so i must use my mother's reading glasses "very close" to understand something LOL.
Yes, i understand that the MIO was the winbond W83627DHG i downloaded the datasheed and find the pin near 67 to 70 i must soldering tailor's pins

to try to measure Mr. Winbond.
Seems that every coil w 2/3 CMOS and a 8 pin chip control some voltage,like if was many power supply, in the processor are 4 ...
when i test in "passive mode" without PSU connected to matherboard the 2 CMOS 70T03GH near the Mr. Wbond measure too low resistance.
if i measure by my fluke in diode and resistance mode :
btw Source red and black drain i read 0.145/w res 250 ohm with 0.553 btw Gate(red) and source(black) w 8.20k oms of res
and if i reverse black S red D i read 0.185/w res 293 ohm with 0.553 btw Gate(red) and source(black) w 8.20k oms of res
in all the two ... normal ? is there a scheme for that matherboard to see if there is some components in parallel ?
i mean, for what i read (N or P channel) the diode normally have a 0.4 to 0.9V of drop, on that type of CMOS i see near 0.445/0.5volt.
but 0.145 and 0.185 250/290 ohm it's low ... and leads in all 2 senses.
I am ignorant in this, it will take me some time to understand.
Thanks.
