Main 4.00 MB BIOS image for the Dell Studio 1558 laptop, model number PP39L, marked in the name as 100 percent OK. It is intended for a 32 Mbit SPI flash and is paired with a separate 1 MB EEPROM file for the board's secondary chip. Technicians write it with a programmer such as a CH341A to fix a corrupt BIOS, a boot loop or a black screen. Dump the original chip before erasing, since service tag data stored in it may need to be kept.
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 @biosbigarchives. Enginerys does not host this file.
