Hi! Have you already replaced your display with a new one? And what is the problem now with the new display? On 12/11/2019 at 2:03 PM, GregK said: Everytime I start the T450s I get the 5 beeps-5 beeps error and disabling the TPM security chip in bios does NOT solve this error. Does this problem exist with your modded bios too? No. With my unlock you don't get the 5 beeps-5 beeps error. Quote Link to comment Share on other sites More sharing options...
GregK Posted December 11, 2019 Share Posted December 11, 2019 Dear Klem, Thank you for your reply and for your help. 1. I already replaced/upgraded the display and I have no Brightness control. I'm using Windows 7 x64. 2. I understand. So, I guess I will try these steps as soon as I have the modded bios flashed back into the chip. If I remember correctly TPM and Security Chip are the same in the bios menu security tap. Do you mean by Security Chip the Secure Boot Option?

sb.bouilouta Posted March 11, 2020 Share Posted March 11, 2020 Hi everyone! I'm new on this forum. I own a Thinkpad T450s, which I want to turn into a Hackintosh. So I have extracted the bios with a raspberrypi. I want to mod the bios in order to get advanced option and to obtain DVMT pre-alloc settings to 128MB. I'm willing to donate if someone can make the neccessary modification on my file. Link: https://drive.google.com/open?id=12LWd15bGqLf0hekr6fjGKbJDnuYOHMQF Thanks a lot, Sofiane.

Yes, you can send me (via PM) your bios dump which was made using any SPI programmer (like CH341A), or upload it to any fileserver ( for example https://www.sendspace.com/ ) and send me the link. Just read the first post of this thread. Quote Link to comment Share on other sites More sharing options...

Bios Modder Klem Posted May 21, 2020 Author Bios Modder Share Posted May 21, 2020 16 hours ago, pitchdown said: Hello, today i did the whitelist succesfull for the LCD. Only problem now is the 2 X 5 Beeps at every cold boot. The options for disable the security from KLEM didn`t work for me. I did this options after flashing the new bios-file. Anybody with options? This laptop have special TPM/Security chip, every time when laptop start, this chip will check special RSA signature.When the BIOS integrity test fails, a sequence of 5 whistles is issued twice at boot. After modifying to remove whitelist (enable unauthorized WI-FI cards), enable advanced menu, etc. the BIOS can't pass the integrity test (because bios was modified), and therefore sequence of 5 whistles is issued twice at boot. In this case, I know only these ways (sometime it's can help, but sometime no) : Set (in bios setup menu) TPM to Inactive (not to Disabled) after flashing. Set (in bios setup menu) Security chip to Disabled. Set Intel AMT module (in bios setup menu) to Disabled. Set Anti Theft Module to Disabled. Set Computrace (in bios setup menu) to Permanent disabled. This setting helps most often. Quote Link to comment Share on other sites More sharing options...
