[REQUEST] Lenovo V570(c) (44CNxxWW) BIOS Unlock

[Serg_ul]

Hello,
Initial info:
I have notebook Lenovo V570 with MSATA SSD 64 Gb and HDD 500 Gb, situation is next:
I buy Optibay [2-nd HDD caddy] for install 3-th HDD, but after I install the 3-th HDD notebook load only up to logo LENOVO, but I can go to BIOS, in BIOS I can see all three disks, but OS or other programs from flash card do not load. When I remove one of HDD, no matter one of the HDD or MSATA SSD, all works perfect. In program "intel rapid storage" I can see that SATA controller can manage 4 SATA conections, after that I make conclusion that it is some restriction on BIOS level.

So question:

Can exist way to unlock BIOS to use all three discs.

For BIOS see link bellow:

Hello, I've managed to activate Advanced tab without modding firmware (soft unlock).

You need to set byte 0x3 in OilSetup NVRAM variable to 0x0, it's responsible for Advanced tab.

It seems impossible to do this via efivars interface in Linux, but in UEFI Shell you can dump this variable (via dmpstore), open it with hexedit, find 4-byte little-endian number 07 00 00 00 (attributes mask) and go to 4th byte from it, or dump this variable with Power Beep(0x2) setting turned on and off to find which byte changes and the next byte from it is one you are looking for. Then just put this variable back to NVRAM by dmpstore.

Here is a dump of Setup menu in latest (44CN43WW) v570 firmware extracted by UEFITool and Universal IFR Extractor, so you can make sure that there is such hidden setting.

And remember, that loading default settings will hide this tab and you'll need to reenable it again.

It is not clear how to do it when I change the parameter Power Beep in dmpstore no change.

Hi, I'm trying the same unlocking method on Lenovo U410. Everything goes fine until I need to write the modified variable back. If I make any changes at all to the file, it fails. If i don't, it allows me. Is there any solution to this? Am I doing anything wrong?

Hi, I've got Lenovo V570 running with 44CN43WW bios
There is a problem:
I have hdd + ssd (case hdd enclosure odd), and it works fine.

Also I have empty mSata port and I want to use it with mSata ssd.
The mSata port works, I have tested it.

But when I try to start my notebook with hdd, ssd(odd) + ssd(msata), it loads bios and stucks at Lenovo splashscreen

I have tested:

• hdd + ssd(odd)
  
• ssd(odd) + ssd(msata)
  
• hdd + ssd(msata)
  

They are all work.
Also I have eSata port, eSata to Sata cable, Sata to mSata closure, and I have tried to mix configuration of ssd's and hdd with eSata, mSata, hdd(odd), hdd.
It boots if I connect only two disks, then I try to boot with three disks it stucks.
If I connect third disk though eSata(hotplug) after bios boots it works fine.

Also I have tried to boot from Boot Menu, and select disk manually, it doesn't want to boot.
I have bios with unlocked whitelist, and Advanced Tab, so I have played with Uefi\Legacy boot, but it doesn't help either.
I can't find secure boot settings in bios.

I think there are some limitations or errors in bios, or it can be secure boot

Please help. I can pay for that. Thanks

Bios.rom backup made by UEFI Winflash is attached.
