BIOS dump labelled for a Dell 820, with OG likely marking an original read from the chip. The name carries no board number or revision, so model details beyond that are unconfirmed. The 1 MB raw BIN suits an 8 Mbit SPI flash and can be written with an external programmer. An original dump is valuable for restoring a board to its factory state. Verify the target chip size and board before flashing, and save your own backup of the current contents.
