Working BIOS dump, marked as fully functional, for the Wistron Bullet motherboard 12295-1, with the HP-style part code 48.4LU01.011 also included in the name. The archive is a RAR of about 8.3 MB. This board is used in the HP EliteBook Folio 1040 family. Flash it with an external SPI programmer when the machine does not POST due to corrupted firmware. Save the original contents first to keep serial numbers and keys, check the PCB number and revision, and confirm the image size matches the flash chip.
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 @biosarchive. Enginerys does not host this file.
