Hello.
On the motherboard, under the BIOS chip and to the left of the processor, there is a 12-pin “DEBUG1” connector.
The lines from this connector go to the BIOS chip:
Bios Chip:
8 7 6 5
1 2 3 4
The “Debug1” connector:
12 11 10 9 8 7 6 5 4 3 2 1
1 pin Bios – 8 pin Debug1
2 pin Bios – 7 pin Debug1
3 pin Bios – 3 pin Debug1
4 pin Bios – 2 pin Debug1
5 pin Bios – 5 pin Debug1
6 pin Bios – 6 pin Debug1
7 pin Bios – 1 pin Debug1
8 pin Bios – 12 pin Debug1
Where do the other lines go from the connector “Debug1” (4, 9, 10, 11) I don’t know.
As I assume, using this connector, you can sew a BIOS chip without soldering it from the motherboard.
Am I right?
If so, please tell us how and with what to connect to it?
