Lenovo M920s - resizable BAR mod?
#1
Greetings,

I've completed the mod that would allow the stock BIOS to support resizable BAR for the Intel ARC A380 that I have installed. (see: https://github.com/xCuri0/ReBarUEFI)

I am currently stuck on not being able to flash the modified BIOS. The stock Lenovo tools will not allow it, which I kind of figured would be the case. Does anyone know if there is some way around it? I've researched and found that maybe Intel FPT is what I'd be looking to use, but I am not 100% certain that's the case and really don't want to brick the machine. Confused

Thanks,
Digits

System Specs:
Intel i5-8600/32GB Crucial DDR4/512GB TeamGroup NVME/2TB TeamGroup SSD/Sparkle Intel ARC A380 - running Fedora 39.

This Thread is Google Hit #1 for "m920s resizable bar", so i thought i'll add my failed attempt here. Maybe it'll help others, maybe someone might find another way.


- used the USB Drive Package, UEFI M1UKT77A/1.0.0.119  25 Apr 2024
- successfully Inserted the ReBarDxe Module to the PciBus Module
- used UEFIPatch with the ReBarUEFI projects patches.txt -> none were applicable
- tried to enable hidden 4G decoding -> no hidden option
- the UEFI does not provide such Option, but i flashed it anyways 
-- to answer digits' question: format a flash drive to fat32, put all content of m1ujt77usa.zip onto it's root, replace the imageM1U.ROM with the modified, boot from it. After 2 promts it will start flashing. 
- Result: ResBar is not working

- It meets the following criteria in DTST patching section:
| Systems without 4G decoding even in hidden settings, this fix will only work in Linux for them though (atleast with GPUs)
- Tried to find the GUID for DSDT modification, no matches

Gave up at this point. Good luck to the next guy, i'd be happy to find your mail in my inbox Wink

(09-29-2024, 01:33 AM)There is a hidden GPU option for 4G decode. Wrote:
  • You have to search for  "Above 4G" and you will come up with:
  1. 1) "Memory Remap" and Edit:Guide says not to mess with Memory Remap as it is not the same. 
  2. 2)"Above 4GB MMIO Bios assignment"
  • You then follow the modGrubShell instuctions to enablethe second of these. After  the second of these , GPU-Z shows 4G encoding enabled. Edit:GPU-Z can't really tell if 4G encoding is enabled.
