Raw 4 MB BIOS image for the ASUS K42JR, mainboard revision 4.1. The file size corresponds to a 32 Mbit SPI flash chip, the type a technician writes with an external programmer when the board is dead or stuck after a failed update. Revision matters on ASUS boards, so read the revision on the PCB and confirm it is 4.1. Save a copy of the existing chip contents first, both as a fallback and to preserve serial data.
