Hi everyone,

I bought a used Dell OptiPlex 3090 Micro with a BIOS administrator password that I cannot remove. Dell support refuses to help without the original proof of purchase, and the seller is unreachable.

I would like to try flashing the BIOS chip with a CH341A programmer, but I need a clean SPI BIOS dump for this exact model.

Here are my machine details:

Service Tag: 50P1BB3

Express Service Code: 10925963391

Form factor: Micro

I can share my current BIOS dump (read with CH341A) for comparison if needed....
