[Request] Insyde embedded AMD BIOS disable secure boot

[agent2003]

Hi,

Please could somebody help me disable secure boot for this Insyde embedded AMD system BIOS? It will currently only boot from an embedded flash chip. It recognizes a bootable USB but won't boot from it due to secure boot.

Dumped the file from the 25Q64FWS1Q flash, tried to mod it using H20EZE and burned back to a 25Q64FWS1G unsuccessfully. I've burned the original .bin back to another 25Q64FWS1G chip and it boots OK.

The BIOS is super locked down, only showing BIOS version, memory, date and time in the setup utility, but I only need to disable secure boot so I can boot from USB or SATA.

Thanks!
