You can use bios_extract utility for that (however this particular
BIOS image causes bios_extract to segfault):

Workplace ~/work: unzip 7642v12.zip
Archive:  7642v12.zip
  creating: 7642v12/
 inflating: 7642v12/7642v1x.txt
 inflating: 7642v12/A7642AMS.120
 inflating: 7642v12/AFUD4310.EXE
 inflating: 7642v12/How to flash the BIOS.DOC
Workplace ~/work: cd 7642v12/
Workplace ~/work/7642v12: ../bios_extract/bios_extract A7642AMS.120
