i hope i got in here somehow!!!

it is still not the main bios. or maybe its corrupted. its usually w25q256JV. if the chip has no 256 number its not the main. it should have 256. it will dump 32mb not 17mb.

hi there!
I am trying to make a backup and post write of the dell 5420 bios and 8FC8 bios. Is the CH341A required to have the 3.3V modification?
Today they let me use EZP2019+, I understand that it is compatible with reading and writing the chip xmc 25rh256cxiq. Any recommendation?
Thanks!
