Second copy of a Toshiba Portege R500 BIOS image, 2.02 MB, with no file extension. No board number, revision or BIOS version is given in the name. The size is slightly above 2 MB, which suggests the file may include extra data or a header rather than being a pure chip read, so check it in a hex editor before flashing. A pure image for a 16 Mbit chip should be exactly 2,097,152 bytes. Compare against the other R500 copy and back up the original chip before any write.
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 →
