Unlock Advanced Options in Lenovo B450 BIOS

[NirmalRajmohan]

I'll try to manually enable vt-x for you with a mod and will edit here with the link...

EDIT

Can't be done using the original BIOS...

Can you DUMP your BIOS for me and link it? there are several tools and tutos on web on how to do this....
Also, was this tab Configurations in the BIOS already before the mod? was it working?

Configuration tab was present even before the flashing, after the flashing it is not working. A new tab is added (Advanced).

I have created a BIOS dump using 'BIOS Backup Toolkit V2.0'. Please find the attachment.

Hey donovan, this version you linked is 0.3

Lol, how'd I do that? Just fixed it. It has the same URL, so you can get it from the previous post

[BDMaster]

It is in Advanced CPU Control (sub-menu) if not appear it's hidden so unlock and will be visible !
Setting: VT Support, Variable: 0x1AF [1] default (It's enabled by default)
Option: Enabled, Value: 0x1
Option: Disabled, Value: 0x0

Into bios backup You will find this register 0x1AF and if it's = 0 then is disabled !

Hey BDMaster. Sorry I haven't been online in a while. Nice to see this forums staying busy!

So for IFR, I use the C programming language notation to indicate the size in bytes of the variable storage, [size in bytes]. Unfortunately EFI's IFR doesn't indicate the default value like UEFI's does. So for this setting:

Code:

Setting: VT Support, Variable: 0x1AF [1]

It's variable storage is located at offset 0x1AF at it takes up 1 bytes

The notation Universal IFR Extractor uses is:

Code:

Anything in parentheses, (), is additional information
Anything in brackets, [], is the size in bytes
Anything in braces, {}, is code

And incase you didn't notice, I got version 0.5 uploaded

I am very happy to see You (I think U very busy or studing), I am exsausting to follow this carousel.
Thanks for your expanation as Always You arrive to help me ! (guardian angel)
Ok now I mean it clearly.

WOW !!!!! U're the Best ! It recognize EFI - UEFI remember form got IFR.txt and get right folder to write it !!! MASTERPIECE !

regards

Have you tried navigating on BIOS tabs with numbers keys? on My notebook if i press "5" jey it navigates to the fifth tab, baybe you can try to go to advanced tab this way?

I can navigate to Advanced tab, but it only contains Legacy USB Support, SATA Controller Mode. 'SATA Controller Mode' is already present in the Configuration tab before the flash. After the flashing I can use the arrow keys to navigate to 'Configuration' tab but as soon as I reach there, system is restarting.

fjfc, it seems that we can enable VT-x by changing some variables in the BIOS (I am not an expert ) BDMaster also mentioned something like that.

If you want I can reload my orginal BIOS and dump it for you.

I have reloaded my BIOS.
