[REQUEST] Lenovo ThinkPad L450 (JDETxxWW ) BIOS Unlock

[Oleh]

Hello Oleh. Please read the first few posts to get all the information needed (like my bios dump).
I want to set the dvmt pre-allocated size from the default value 0x1 (32mb) to value 0x4 (128mb). I tried using the efi shell command "setup_var 0x37 0x4", but it can not find the variable and does not change the value.

It jsut returns another grub> prompt. So my request is the following:
A) help me change the value
B) create a BIOS which has the dvmt pre-allocated size set to 128mb (variable 0x37 set to value 0x4)
C) create a BIOS which unlocks me setting the dvmt pre-allocated size

with either of A,B or C I would be very very happy

perhaps all that is in the advanced settings of your BIOS. Give me the exact configuration of your notebook and photo menu of your BIOS.

Ok my notebook is an Lenovo L450 with Intel Core i3 5005u Broadwell processor, 8gb ddr3 1600 ram, 128gb ssd and phoenix BIOS. I think every technical detail is in the Report.html I uploaded. Here are the pictures of my BIOS. In the "config" tab there is the menu "display" which I made an extra photo of. If I should make a photo of every sub-menu just tell me.

which chipset laptop?

[kaiomatico]

Well I guess it is an Intel 9 series. Because the intel chipset driver says it supports chipset version 8 and 9, but broadwell processors need chipset version 9. According to the uploaded Aida64 Report the chipset is:
Intel Broadwell PCH-LP, Intel Broadwell
I hope this is enough information. I cannot define more precisely like for example h97m or anything like that I guess... or maybe in Linux?

Phoenix is new to me. Most likely with a usb dos stick with "phlash", right? but how can I dump the current bios in case I need the crisis tool because of a bad flash?

flash and report

Should I try the efi version instead? Can I run it with rEFInd bootloader or do you have a different advice? I correctly renamed your file to bios.rom first
