Which revision of DASS8BMBAE1 do I have?
Files for this board mention Rev E. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
What should I check before flashing the DASS8BMBAE1 BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 4 MB images; the dump size must match your chip.
