In this example, we found the menu header is “00 14” 00 = Pick Field & 14 = Length. In this example, it is clearly we’re going to unlock or unhidden Pick Field type of menu. This type of menu allowed us to change the value such as enable/disable or change it to another value. The two bytes before “0A 03” will determine which type of menu it is & we will call it menu header to differentiate it from others:a) Pick Field type of menu.

Note:00 = Pick Field 01 = Pick Field 10 = Generic Text 11 = Information 21 = Time 22 = Date 23 = Free form Hex - Depend on the type of the menu we’re going to unlock or unhidden but usually we’re going to unlock or unhidden two types of menu. Remember, the first result is what we are looking for.ġ3) Open TEMPLAT0.ROM with HEX editor & search for “0A 03” (030A in endian format):. In this example, the offset for “FD 2C” will be 030A. Make sure search from the beginning of the file:. 12) Now search for “FD 2C” (2CFD in endian format) in the STRINGS.ROM file. In this example, we found out that the offset or location of the “Intel(R) Virtualization Technology” string or text is 2CFD. In this example, we will found “Intel(R) Virtualization Technology”:-ġ1) Search for “Intel(R) Virtualization Technology” in the STRINGS.ROM file:. Delete the header & save it as STRINGS.ROM:-ġ0) Search for “Intel(R) Virtualization Technology” or “VT Feature” or just “Virtualization” in the STRINGS window in PBE. The 01 00 02 00 means there is one language in this file which is EN (US).ĩ) All of the bytes before D6 70 are called header. In this example, the two bytes are D6 70:. 7) Open OLD1.RLS with HEX editor & copy the first two bytes:-Ĩ) Open STRINGS0.ROM with HEX editor & search for the two bytes, copied from the OLD1.RLS file above. 4) Open the BIOS image with PBE:-ĥ) Go to PBE’s TEMP folder:- 64bit OS: C:\Program Files (x86)\Phoenix Technologies Ltd\BIOS Editor\TEMP - 32bit OS: C:\Program Files\Phoenix Technologies Ltd\BIOS Editor\TEMP 6) Copy OLD1.RLS, STRINGS0.ROM (or STRINGS00.ROM) & TEMPLAT0.ROM (or TEMPLAT00.ROM) files from PBE’s TEMP folder to working directory.
PBE have known issue where it (sometime) unable to extract the BIOS image properly & this will lead to bad BIOS image after re-build. The extracted files are useful if PBE produced error(s) while re-building the modified BIOS image. WPH file) using Phoenix SLIC Tool/Mod (current version at time of writing this tutorial is 1.42):-Īll extracted files will be located in DUMP folder. WPH) from the compress file or EXE file (BIOS self-update software) to working directory.

1) Create a working directory, let say: C:\BIOS_MOD 2) Download & extract the BIOS image (.ROM or.
