A 2 MB BIOS dump for a Dell model identified only as 1545, likely the Inspiron 1545 laptop series, with no revision or version given. Technicians use this kind of raw image to reprogram the flash chip off-board or in-circuit when the original firmware is corrupted. Confirm that the chip on the board is 2 MB and verify any service tag or system data after flashing, as a dump from another unit can carry foreign identifiers. Back up the existing chip before writing anything to it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
