I've been downloading modified BIOS's from the forum for a few years now and I would like to learn how to mod my own BIOS's. I have a Lenovo Thinkpad X230t the I would liKe to do the following mods to:
1. Whitelist removal. - This part seems easy enough as there are plenty of examples on the forum
2. Unlock advanced BIOS menus.
3. Disable genuine battery check. - I just had to pay $90.00 USD for a new battery for one of my X230's, (I have two, plus 2 X220t's, X201, X61t and a T60. What can I say, I like Thinkpads!).
Any suggestions.advice on how to proceed would be greatly appreciated!
Thanks

Hi
Your bios chip is rewrite protected
Bios mod can be flashed using SPI-programmer+SOIC8 clip only
Hi Dudu2002,
Thanks for the response. I have a Raspberry Pi and a SOIC 8 clip that I am using to read/write the BIOS chip. Here are the commands that I am using:
#####
sudo flashrom -p linux_spi:dev=/dev/spidev0.0 -c MX25L3206E/MX25L3208E
flashrom --programmer linux_spi:dev=/dev/spidev0.0 \
--chip "MX25L3206E/MX25L3208E" \
--read original_4mb1.rom
flashrom --programmer linux_spi:dev=/dev/spidev0.0 \
--chip "MX25L3206E/MX25L3208E" \
--read original_4mb2.rom
diff original.4mb1.rom original.4mb2.rom
flashrom --programmer linux_spi:dev=/dev/spidev0.0 \
--chip "MX25L6405" \
--read original.8mb1.rom
flashrom --programmer linux_spi:dev=/dev/spidev0.0 \
--chip "MX25L6405" \
--read original.8mb2.rom
diff original.8mb1.rom original.8mb2.rom

However, when I try to read the extracted rom with Phoenix BIOS editor, it get the following error:
"No BCP's found!"
Am I using the wrong editor? I thought that the X230t was a Phoenix BIOS.
