Hello i want to edit BIOS .
for exemple i want to edit bios :
Someone can help me whit tool ?
I try whit eeprom.exe in dos .
" eeprom.exe w a0 a7 'hex code' " <- at Lenovo Y50-70 , Yoga 710 , B50-XX . it works
but for Yoga 900 , Y700 , Ideapad 310 , Ideapad 510 - don't work .
my question is :
Why at the Yoga 710 it works and for Yoga 900 no ? ( possible is work but I don't know where is SN in bios , maybe is another string ? )
You need to use LVar32.exe/LVar64.exe
EEPROM.EXE is for Compal ODM systems. LVar32/64 is for LCFC ODM.
ODM = Original Design Manufacturer
When you buy a Dell/HP/Lenovo system you're actually buying a device that was manufactured by an ODM
The big PC vendors use a variety of them for their systems so one system in the same family might be made by Compal and another might be made by LCFC.
I found the lvar.exe .
but at lenovo g50-80 dont work
i don't know why tell me Wrong parameter, please check it.
You have to use a /r to read or a /w to write. Thats what they mean in the usage.
i used lvar.exe /w /ln /c "xxxxx" and WORKS
Has anyone got a link for LVar64.exe? I have a Lenovo Y700 looking to modify.
sir how can i change s/n number of lenovo y50-80 ??
