Hi,
Is there any instructions for unlocking the bios with Seeprog programmer, and what do I need to do? Do I need to un-solder 24rf08c chip, or read from mainboard. I can not find this zeder diodes in my country, is there some other diode to use??? THX |

The only instructions are to read the chip with R24RF08 and that works with the SIPROG or driven programmer.
The zeners are 5.1V but it will work with 4.7V too.
