Hello. Can somebody unlock advanced options menu in my bios? I found some utility that backed something up, but I'm not sure if I did it right.
Model: Acer E5-571
BIOS: v1.32
I did it myself. FYI: VT-d is enabled by default in this laptop if you wondered. In case anyone wanted to know how to change it:
1. Not sure if it's required (I had it disabled from the very beginning), but disable Secure Boot in BIOS.
2. Download this pack of software:
https://drive.google.com/open?id=19vtEKW...RCrTo_wzl7 - it's a backup utility I found somewhere in the net, Universal IFR Extractor and the only EFI Shell which worked with my laptop.
3. Unzip everything and run BACKUP_Tools12_2.exe. It will back your BIOS up and put it on your desktop in a file "result.rar". Open this file and unzip one of the "x32_bios-region_xxxxx.bin" files. I had three of them, they were all identical and the size of exactly 6MBytes.
4. Open "x32_bios-region_xxxxxxx.bin" in some archive manager (worked for me with 7-zip). Unpack "Insyde.vol/SetupUtility.efi".
5. Open Universal IFR Extractor and point it to the "SetupUtility.efi" file. Hit "Extract" and save the file anywhere.
6. Open the file you just extracted in your favourite text editor (Notepad++ for me).
7. Find the option you want to change (I didn't actually manage to unlock advanced settings, but I did manage to change anything inside it this way). Use CTRL+F and look for the keywords (for example, it's VT-d for me). You'll find a structure which looks like this:
Code:
Setting: VT-d, Variable: 0x1EB {05 A6 E1 02 E2 02 12 01 34 12 EB 01 10 10 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00}
0xB5F4A Option: Disabled, Value: 0x0 {09 0E 05 01 00 00 00 00 00 00 00 00 00 00}
0xB5F58 Option: Enabled, Value: 0x1 (default) {09 0E 06 01 10 00 01 00 00 00 00 00 00 00}
0xB5F66 End of Options {29 02}
Note down the variable address (0x1EB here) and the option you're interested in (I wanted to enable it, so it's 0x1 for me).
8. Format a USB key in FAT32. Create a folder named EFI, and another folder BOOT inside it. Put BOOTX64.efi in the folder boot, so it would look like this (my USB is E):
E:\EFI\BOOT\BOOTX64.efi
9. Reboot to your USB key (the boot menu is F12, or if you have it disabled you have to enable it in your BIOS - it's F2).
10. Use the following syntax to change a variable:
The shell will show you the previous value and the confirmation that it's changed now. You can change more variables from here if you want to, there are many interesting options in this BIOS!
11. When you're done, write "reboot" and hit enter. That's it!
