Do you really not see the difference between reflashing with programmer and measuring in standard scheme:D?

I found a difference between the two matherboards.

both disconnected and with the batteries inserted, measuring in homs-resistance, with the grounded black connector and the red on the flash
In this part you said about measuring in standard scheme, where RTC battery stayed in its standard place.
In standard scheme RTC battery isn't used for operations with SPI flash.
When you want to reflash ROM with programmer, you can use different sourses:).

where can i find the references you posted ? (VSB LDO PSIN#, PSOUT#, SUSB#, PSON#, RSMRST# pins (MIO).
+3.3VSB - +3.3V standby voltage.
LDO - low dropout regulator.
PSIN#, PSOUT#, SUSB#, PSON#, RSMRST# - you can read documentation for MIO in your motherboard (P5B-VM DO - W83627DHG, if I'm not mistaken).
