Okay thank you. I know there's multiple types of hardware programmers, would you know which I should be looking for?

Oh well, it depends on the type of the BIOS chip you have, here in forum we have great material regarding that, with methods done by desoldering and soldering back BIOS into the motherboard or even without the need of desoldering it, see:

Desolder / Solder method:

http://www.bios-mods.com/forum/Thread-TU...8#pid68768

With a SOIC8 test clip, no need to desolder the BIOS chip (if your BIOS is SOIC8 type, wich is higly likely... you can use it) (Post #17):

http://www.bios-mods.com/forum/Thread-RE...6#pid68766


The programmer, it depends on what kind of chip you got... but most likely to be series 25/24 (You can check this using the program I sent to you earlier , the one you made the backup with, if you run fptw.exe -i it may give you the CHIP reference)

If it is series 25/24 SOIC8, then just this would be sufficient:

clip for flashing it without desoldering:

I have lenovo flex 14.I think my bios chip winbond 25064 viq 1323.I want to remove white list.Do I have to use hardware program,or is there any shortcut by software

[swordfish74]

I attached a picture.My question is flex 14 have only one bios? Is there any backup bios(dual chip).because I couldn't see other bios chip,may be winbond chip isn't bios chip.
