[Request] Lenovo Yoga 3 Pro-1370

[mwepstein]

Hi, I have a Yoga 3 Pro. I'd like to modify the BIOS so that the DVMT Pre-allocated Memory setting is set to 128 MB.

I tried changing this setting with EFI Shell by inputting setup_var 0x18C 0x4 but unfortunately the BIOS are locked.

Here is a link to the current BIOS from Lenovo: http://support.lenovo.com/us/en/downloads/ds101338.

Will an unlocked BIOS allow me to make this change?

Thanks!

Hi BDMaster, thanks!

Here are the results.rar from Backup_Tools12: https://www.sendspace.com/file/7odhnz

And here is the report.htm: https://www.sendspace.com/file/knibe2

When I use Universal BIOS Backup I get an error: can not identify the bios. However, it creates a file called PhyDMACCx64.sys. Should I upload that as well?

Error 280 !

Try to check the Sleep Bug if is Actived yet !
So put your laptop into Sleep Mode (Close the Lid), and then
Wacke-Up It (open the Lid), then redo the result files !

If this way will not work then . . .
I am sorry only using an SPI PGM + Clip We can do this job !
Look here :

Unpack the result file using WinRar v.5.20 or above and look You too !
So only by SPI PGM We can do It !

Ok, thanks for the help. I thought this would be the case, I tried modifying the BIOS with phoenix tools and had similar problems.
