I don't know what makes the difference between asus and lenovo boards. (probably a resistor strap in ITE chip)
Seems that this board have the same reprogramming function for ITE chips as Asus motherboards.
I've found the strap resistor for that function.
Pin 100 of ITE chip is the GPG2 input for strap resistor, and RE44 (10K) is connected to +3VALW_R.
Also pin 100 have a pad to move the strap resistor to gnd.
With RE44 connected to +3VALW_R, there are pulses in pin 1 and 5 of bios chip, but has no pulses in pin 2.
Pin 6 has pulses also but seems they are distorted and with low peak to peak voltage.
Bios chip is seems ok with the external programmer. It can be read and write without errors.
Diode mode readings of pin 6 is .244 but pin 1,2 and 5 are .469
I will check the spi bus rails and post new findings.
