Quick Start:
|
|
|
|
|
|
|
|
|
|
To fetch the firmware from Lenovo, extract, decrypt and patch
|
|
|
|
|
it, ready for more patching, choose one of:
|
|
|
|
|
|
|
|
|
|
make x230.G2HT35WW.img
|
|
|
|
|
make t430s.G7HT39WW.img
|
|
|
|
|
|
|
|
|
|
To update the checksums and encrypt the patched firmware, ready to
|
|
|
|
|
be inserted into the FL2 file, choose one of:
|
|
|
|
|
|
|
|
|
|
make x230.G2HT35WW.img.enc
|
|
|
|
|
make t430s.G7HT39WW.img.enc
|
|
|
|
|
|
|
|
|
|
To re-insert the EC firmware into the bios flash file, use a command
|
|
|
|
|
similar to the following:
|
|
|
|
|
|
|
|
|
|
dd if=x230.G2HT35WW.img.enc of=\$01D3000.FL2 conv=notrunc bs=4096 seek=1280
|
|
|
|
|
|
|
|
|
|
To update your firmware, prepare a DOS boot disk with the FL2 file and
|
|
|
|
|
the dosflash.exe utility and then use a command similar to:
|
|
|
|
|
|
|
|
|
|
dosflash /sd /ipf ec /file $01D3000.FL2
|
|
