So theres no way to hotwire it to re-enumerate the pci devices by reloading one of the pci dxe files?
Also Linux not compatible with software I want to test. Not a big deal though.
Thanks

To my knowledge no. Maybe someone else here knows though.

It’s kinda complicated to setup but a VM with GPU passthrough running Windows should work if you really want to try it.

I would want to try doing a passthrough but the software uses a complicated usb based licensing and networked peripherals that be a pain to get working. I’ll just hack around with the EDK library running pci bus efi drivers and see if that works though not likely. I would mod the bios but if it bricks accessing the motherboard to do a usb flash would be a pain as well as system enclosed in housing that takes a day to take apart. Thanks.
Hello o/
There seems to be two sets of setup menus in this Alienware BIOS.
2 x Main 2x Advanced etc
There are nice things in the more comprehensive menu (Above 4G decode and XMP memory) but it is hidden.
Does anyone know if this is likely to be a service mode menu and a user menu? If so, is there a way to enter it? I’ve tried to google it but have found only malware sites

@68k-dude Just use the setup_var method I linked. It’s a lot easier and doesn’t have any risk of bricking

from what i’ve been experimenting, making the hidden advanced either the 279 or 2DA to USER would make it appear on bios sometimes, to make hidden menu appear, you need to make the Handle you want to make it appear as USER. it worked on my H77 DS3H, now i could enable and disable above 4g decoding without grub:
Since i want to access the hidden menu one, its on handle 0115 below ATA Port, i set the invisible option below ata port to user:
and set above 4g at user (even if its not hidden after unhid the invisible menu):
this is the result:

Hello everyone, sorry if i have a bad english it is not at all my native language and im trying my best i hope to be comprehensible, so i am trying to add resizable bar support to my MSI B150 PC MATE
I followed this guide : GitHub - xCuri0/ReBarUEFI: Resizable BAR for (almost) any UEFI system
Ok so i downloaded the latest version of my bios which is a CE0 file ( idk if it is important but to be cautious im saying the details )
i used UEFITool to add the ffs accordingly to the guide
Ok nice i saved everything and i have my .rom file ready to be flashed !
I tried to use the classic FLASH-M interface on the bios setup, does not work. Does detect the usb but not the file.
So i tried to make my usb bootable and boot on it with the file directly ( like the guide on this site sugest ) and it does not work ( black screen showing " no bootable device found " )
I tried to tickle around my bios setting going into legacy/uefi and also my usb rufus setting even trying linux UEFI/GPT usp setting on rufus, i tried brute rename the .rom file to .CE0 nothing is working
im running out of ideas if anyone can help me somewhat i will be very thankful !
I am a new user i can’t upload file through the site but here a link : https://anonymfile.com/4YxN8/b150-rebar.rar
Someone suggested me to use AFUWin64
ok so i’ve finally done it using AFUWIN !!!
Hello @Marzouqi2000,
Excellent 
I was going to suggest that but I wanted to check the file was OK first.
Are you able to get the BAR size you want?
Hi,
Was wondering where in the bios is the best place to insert this dxe file? Was looking inside a Z270 AMI Asus bios and noticed that the last two bios volumes are duplicates. Which one is best? Need only place in one volume? Thanks
DXE file should belong to DXE volume. Place it near to other DXE drivers.
If not enough space left, it is safe to remove drivers from DpcDxe to Udp6Dxe.
Hello @davidm71 ,
Which board and file in particular?
I don’t think I have seen two DXE areas in two identicle volumes before.
It would be nice to have a look.
Best regards,

Experimenting on a Z270-WS Asus board. The last four volumes are duplicates meaning they exist in pairs but was able to find the DXE volume by searching for NVME key phrase where it was hiding in the 5th to last volume. No problem.
Thanks
in GUID A03… (Its in the buttom of volume before the first PEI volume)
Hello @davidm71,
As @Koekieezz has said.
Insert the ReBarDxe.ffs file after A0327FE0-1FDA-4E5B-905D-B510C45A61D0
Save as xxxxxxxxx_modified and check that the file size hasn’t changed.
Good luck and If you get stuck post the issue for us to help with.

since that is where the orom stored and other, i think it is the equvalent of CSMCORE in older aptio 4 bioses, but also whenever i insert rebar dxe, it works (for 100-200 i usually do in github)
I like MMTool as it is sometimes easier to see where the silly DXE section is
