Dumped with CH341A https://drive.google.com/file/d/1Eni7yn9...sp=sharing
Hi,

I have modded the bios for a T450s using the ch341a programmer. The mod works in that the new LCD screen added to laptop now works with brightness controls.  However, on startup I always now get the 10 beeps (5 beeps x 2).  Reading around it seems this is an issue with TPM or some related security feature.

Is there a known reliable way to remove the beeps? I have tried a few things in bios relating to TPM but nothing seems to have an effect.

I really need to get these beeps removed if possible.  I am assuming the bios checksum is now failing due to the screen whitelist mod that was performed and probably need to get the correct checksum value put in.

Would really appreciate some advice on this.  Many thanks.
