      Hello.
I try flashrom on old motherboard EPOX EP-3PTA with PLCC32 socket.
It probe & read flash well, but not erase nor write new bios.
I try with native Winbond W49V002FAP bios chip & with 2 SST49LF002A.
Here output of my script file
#!/bin/bash
# get information about flash chip & BIOS
name="W49V002FAP_on_EPOX_EP-3PTA"
sudo /usr/sbin/flashrom -V > $name.V.txt
sudo /usr/sbin/flashrom -VVVr $name.flash > $name.Vr.txt
sudo /usr/sbin/flashrom -VVVE > $name.VE.txt
#try to write bios from another chip SST with serial number 006478394
sudo /usr/sbin/flashrom -VVVw /home/alex/src/flash/006478394.flash > $name.Vw.0064.txt
