Ya programe chip BIOS, revise la fuente principal y esta bien y el CHIPSET no esta en corto. pasa que en el lugar donde ponen en funcionamiento la maquina mantiene conectada por LAN y hay muchos bajones de energia y necesito el schematic para poder revisar que componente es y cual es su funcion.

read error you need check tool and chip BIOS. this is hardware i can help more
 
Is macbook working or dead right now?

I suppose it will not work if I cant read the chip, the iMac will also not be able to read it.

I will solder back the bios chip and check.
If not working, can I use one of these dumps here is this thread?
Thanks once again

yes, If the macbook is still working I recommend you use another chip to program the bios in this topic to try it out

iMac status :
Right now the machine turns on first led steady green. then turns on 2nd and 3rd led for half a second and comes back to first led only.

Repeats this like in 5 secs intervals.

Machine specs are here below.

Would you help me to get a working bios file for this model? thanks
