BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.
