Hi!

Ok. Check PM.

 

Thank you so much for your help.

 

The menu options are fantastic and now I can run my 16Gb HyperX @2133Mhz.

I was able to stop the 5 + 5 beeping but don't know if it's permanent so I'll update in a week or so.

 

Now just waiting for my new IPS panel to arrive and I can really enjoy this little unit.

 

Thanks again Klem :encouragement:

Hi,

 

Here is my original bios. I'd appreciate it if you could remove the screen whitelist, remove the wifi whitelist, and/or unlock the hidden menu.

I'll take anything I can get, but the most important to me is the screen whitelist.

Thanks in advance!

Edit: computer is a t450, i5, and the bios is 1.33

Hello @Klem

 

I have no way of dumping my BIOS, sadly, but I have a T450 that I need to whitelist RAM for. I have the sticks but none of them work on it (they do work on my T420 so I know they're good). Is there a way to mod a generic BIOS to accept any RAM without me creating a dump of my specific one? 

 

The 4GB single-channel setup is molasses slow. 

 

Thank you.

Hi!

In this laptop model, whitelist for RAM modules is not presented.

Hi! thank you SO MUCH for your quick response! Am I right in thinking, then, that the only way of adding more RAM is to find a module that is compatible with it? Is there no way of making it "accept" the sticks I currently own?

Hey  Klem,

I have the same trouble with reading the dump like  izajasz. The CH341A Programmer cannot verify the dump. Auto detect is working. do you have some tip for me?

Dear Klem,

I kindly ask you to modify the bios of my T450s.

The bios is already dumped via CH341a SPI programmer and can be found here.

--> Bios dump

 

Please remove the whitelists for Wi-Fi cards and for Displays and unlock the hidden additional menus and settings in bios setup menu.

 

I already tried to remove the whitelist for displays but had no success. 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?

Any special instructions / bios settings for flashing your modded bios back into the chip? Like disabling TPM, etc.?

 

Thank you in advance for assistance.

 

Regards,

Greg
