RAR archive of 464 bytes simply named DELL, giving no model, panel or resolution. A size this small points to one or a few EDID blocks for Dell notebook LCDs rather than a system BIOS. Unpack and examine the contents in an EDID or hex viewer to learn the panel ID, resolution and checksum before use. EDID repair involves writing the block into the 24C02-class EEPROM on the panel; read the original first so that a wrong image can be undone if the screen goes blank.
