Some methods for module configuration

Pure SW

1. Create a ROMHOLD/Binary image for configuration. The image can embed in BIOS.Need build a toolkit to setting the binary file for PE engineer.

2. Embed the configuration image to EC pace, BIOS can to use specfical OEM command to get the information.


1. Module provide a identification pin, such as a pull high pin, BIOS/EC can to read pin state. a module need allocate a GPIO to read.

2. Use EC/ADC channel to read a identification channel, all module just need a wire-OR identification channel.

    Reduce power leakage, use a gpio to control a N-MOSFET for the idenfication channel power.

When BIOS built ACPI table to fill the configuration information in ACPI table.
