[hcggbe]

Thinkpad L14 gen2 Intel i5-1145G7, The chematic silkscreen is "GL4A0, GL5A0, NM-C632"; One day I try to change the bios feature "Intel TXT" to enabled and save & reboot.
Bad things happened! It does not boot up and show beep code:"0002:internal bus error". I tried to unsolder the bios to refresh the firmware, but unkonw how extract the image block from the *.FL1/*.FL2 files.
Does someone give some tips？ Or just give the back BIOS archive should help me a lot.

Is this your Serial Number "PF3Q03N5"?
This device must contain another BIOS chip (16MB), you should upload its file too.

Don't forget to write the device full model number and motherboard number.

Look for "U2104" on the motherboard, it's a 16MB chip with WSON 6x5 package.
