Bios Mods -The Best BIOS Update and Modification Source

I have this laptop with cpu n4000 and I installed windows 8.1 in it.

W8.0 and w7 won't boot, in w7 I get the "BIOS in this system is not fully ACPI compliant."

The problem I have is with the Graphics card, I can`t see the Intel graphics card listed in Device Manager on Windows 8.1

As I have seen in youtube, for other Lenovo laptops, it is possible in Insyde Bios to unlock the Advanced tab, 

Well, I'll be happy if I can get the graphics cards detected on W8.1 or if I can install w8.0 on it. So I'll need to switch the ACPI version on Bios.

This is a backup of my BIOS I made with the command:  H2OFFT-W.exe backup.bin /g


IMPORTANT! I updated my bios two days ago to the latest official version to see if it can change things and as I read in the readme.txt file, this is some important things to consider:

The changes in the new BIOS are:
General Information:

7XCN30WW:
BIOS Notification:

1. Fixed
1) N/A.

2. Add
1) N/A

3. Modified 
1) SPI Lock Enable


If flash BIOS to 7XCN30WW, please don't flash back to 7XCN24WW or older version BIOS,or it will cause unit can’t power on.


Backup of my BIOS (backup.bin): https://www.mediafire.com/file/d9jbkn2ju...p.bin/file

Readme file:

Link to the BIOS (I extracted it using 7zip):

I hope you can help me guys, as I read in the forum it is possible in some cases to switch the ACPI version in the advanced tab.

I'll be happy if I can see the Intel Graphics card on Windows 8.1 and I will be more happy if I can install windows 8.0 on it. But without the graphics card detected I can't do nothing in w8.1 or w8.0 or w7

So what I want is No Whitelist + Menu Tabs Unlocked

Lot of thanks

Regards

PD: It is possible to restore the BIOS using Win+B if I brick the laptop?

Hi,

This is a new backup of the bios I made using Flash Programming Tool:

biosreg.bin file -> http://www.mediafire.com/file/usb8lspzi5...g.bin/file

As I read somewhere, it's easy to extract & read the EFI variables from a FPT backup

I hope somebody in the forum can help me this time, please

Thanks,

Regards
