Appreciate everyone's input and advice. I have 2 iMac:
1) late 2009 with i7 860, 8gb ram, upgrade to BCM943602CS, WX4130 GPU, SSD, Monterey(cool 0.3.1)
2) 2010 with i5, 4gb ram, HD4850 with a faulty internal dp connector
The late iMac 2009 seems to be unable to connect to the apple keyboard at the oclp boot picker screen. So.. I wanted to flash the 2010 bios onto the iMac 2009 with a CH341a programmer.
Did it this morning. Used CH341 to read both bios chip and saved both. program the imac 2010 bios into the iMac 2009. Ch341A program said it was successful, but when I verify, it says mismatch. I power on the iMac 2009 and check that the bios on iMac 2009 didn't change. So... Would like to ask if it is even possible? Using CH341A programmer v1.01. Thanks.
