BIOS dump for the LB46E motherboard, Wistron board number 10307-2, with the code 4HK01, supplied as an 880 KB zip. Wistron uses five-digit board numbers with a revision suffix, printed on the PCB. The archive is small, so check the extracted file size against the flash chip before you program it. The image may cover only part of the chip or need padding. Always read and save the existing chip contents with your programmer before writing anything.
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.
