Could someone do a tutorial using AMIBCP 4.53.0050

What should edit?

Captura de Tela (19)

 

Check the folder under main, and enable the settings called hotplug below the PCIe ports.

Tried this on a Lenovo Z580 with no success. UEFI setting changes stuck without issue, but every time I checked within HWinfo, it indicated that hotplug was still disabled.

Hey guys, so I tried the hot plug solution by extracting my bios, finding the text advanced and using the uefi converter to find my bios settings. I used the efi shell to change my setting from 0x0 to 0x1 (I had to write 0x10 because when I wrote 0x1, it set the value to 0x01). When windows opened I used HWinfo64 to see that the pcie bus I chose had hot plug enabled.

My problem is that whenever I restart my computer it disables hot plug again. When I use the efi shell, I can still see that the value is set to 0x1, but HWinfo64 detects that hot plug is disabled nevertheless. Has any of you guys dealt with an issue like this, and what would you recommend?

Has any of you guys dealt with an issue like this, and what would you recommend? I've read somewhere that it could be caused by a dead CMOS battery, but I wanted to ask anyways.

I'm trying to connect a 6G GTX 1060 using the EXP GDC through a mini PCIE port if that helps.

You don't need to enable hot plug for GTX1060 6G. It will work perfectly just after doing this instruction.

If you never ask, then you will never learn

 Hi everyone, I'm trying to do this on a Dell Inspiron 7559 and I already found the variable that I want to change.

I've formatted a flash drive using rufus and put the bootx64.efi inside EFI\Boot.

So I rebooted my laptop and pressed F12 to choose USB (UEFI - OS) under UEFI boot options. Then I got a screen to type the command (but no yellow text as mentioned in the tutorial).

Then I typed setup_var 0x73f and I got an error. See the attached photo. Anybody knows what I'm doing wrong? I'm new on this stuff... Maybe I'm using the wrong bootx64.efi file?

@fndpena, please try again using the older EFI Shell

EFI Shell (there is http://brains.by/posts/bootx64.7z   &&  older version )

eGPU Setup 1.35    •    eGPU Port Bandwidth Reference Table

Well, I feel I'm getting very close to do this, but still not working the way it should. Now (with the older version) is booting on a difference interface with yellow text. 

I try to change the variable to 0x10 and it looks like is working but I can only type one command, the shell doesn't let me type anything else and I have to Ctrl+alt+del to reboot (see attachment). But then I boot in Windows and nothing is changed. I check HWiNFO and the hot plug is still disabled.

EDIT: At least this time the shell finds the variable when I type "setup_var 0x73f" and it shows me the current value (0x0). When I reboot again in efi shell, the value is back to 0x0 even after I have changed to 0x1. I guess this is not changing at all.

I should mention that "Universal BIOS Backup Toolkit" shows my BIOS type as: AMI Bios / ACPI 2.0

Maybe I'm still not using the right EFI Shell?

Awesome tutorial!

I can't access the EFI shell, I tried all the /EFI/Boot/BOOTX64.EFI versions here on this thread, but when I boot from my USB pen-drive it says to press any key to reboot and then it starts loading Windows (after pressing a key, without rebooting).

I can't disable "Legacy Support" or else it won't boot from USB (BIOS won't even detect it), and my Insyde BIOS doesn't have "Secure Boot" option, so can't change that either.

I can boot into FreeDos by using Rufus and a pen-drive, is there a way to enter to the EFI shell from there? Any ideas?

Thanks.
