#1 | [SOLVED] Ideapad 330S-15IKB invalid data on bios datum

Tue Jun 08, 2021 1:12 pm (Last edited: Mon Jul 12, 2021 5:07 pm)

Hello,

I have an Ideapad 330S-15IKB PC whose motherboard I changed today. It comes from the famous Aliexpress site ...
The problem is that the MTM, Product ID etc is not present in the bios and my keyboard does not work on the digital pad side.

I could read that it came from this missing information and I would like to fix the problem.

Is it achievable? I found a website explaining how to extract a bios.exe file and get an editable .fd file but I don't know how to extract the current bios from my computer. Is it necessary or is there a tool capable of rewriting in the bios directly under Windows (or bootable USB key)?

Thank you in advance for your future help :)

Have a good day

Hi friend,
have you the previous bios backup from the older MoBo , have you the System Data to know which were into the older one ?
Have you an SPI CH341a programmer ...
Use this tool run it as Admin and upload the result file :

https://www.mediafire.com/file/4s2lp3ig8...ools20h.7z/file

There are some tools to rewrite back the System Data, but not always working, then it's possible to make hex edit to get it.
Let me know
Regards

Hi,

I can't do a backup from the older MoBo because it doesn't work anymore. That's why i change it for a new one.
I have an SPI programmer , maybe i can try to read the bios from the older MoBo with it ? To be honest, i don't remember how to use it.

The result is here : h t t p s: / / drive.google.com/file/d/1dyyAlCfMwMOeWxbaLS9Gn8mUFJNJoQjD/view?usp=sharing

Sorry, i don't have rights for direct link :/

Thank you :)

@Tiripstruk
It's very easy , you have to download the software for the Win10, ASProgrammer 1.41 , install it (install driver Parallel version), and then connect the clip to eeprom and try to find your eeprom , there is a buttom "?" it will show the Eeprom ID found, double click on the first one and try to read the chip.
Here is the tool :

Let me know

On the old MoBo, impossible to read the ID of the chipset. I put all in the right side , i'm sure of it but all the time, it's unknow. Maybe it must have batterie or adapter plugged in?

Ok friend, so you modified your Firmware as Descriptors are unlocked :

Fixed: Yes
Base: 0h
Address: FF800000h
Offset: 0h
ReservedVector:
FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF
Full size: 1000h (4096)
ME region offset: 1000h
BIOS region offset: 200000h
Region access settings:
BIOS: FFFh FFFh ME: FFFh FFFh
GbE: FFFh FFFh EC: FFFh FFFh
BIOS access table:
Read Write
Desc Yes Yes
BIOS Yes Yes
ME Yes Yes
GbE Yes Yes
PDR Yes Yes
EC Yes Yes
Flash chips in VSCC table:
EF4017 (Winbond W25Q64)
C84017 (GigaDevice GD25x64)
207017 (Unknown)

But you Bios has variables that locked the Eeprom rewrite back , so we have this error :

Error 368: Failed to disable write protection for the BIOS space.
FPT Operation Failed.

Now to rewrite back the Firmware Recovered we have two choices

1. Use the CH341a + Pomona clip
2. Unlock the variables and use Intel Fpt

Eeprom Unlock Mod :

0xA6235 One Of: Flash Protection Range Registers (FPRR), VarStoreInfo (VarOffset/VarName): 0x612, VarStore: 0x5, QuestionId: 0x331, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 BD 11 BE 11 31 03 05 00 12 06 10 10 00 01 00}
0xA6246 One Of Option: Disabled, Value (8 bit): 0x0 {09 07 54 00 00 00 00}
0xA624D One Of Option: Enabled, Value (8 bit): 0x1 (default) {09 07 53 00 30 00 01}
0xA6254 End One Of {29 02}

0xB1E97 Suppress If {0A 82}
0xB1E99 QuestionId: 0x6A equals value in list (0x1) {14 08 6A 00 01 00 01 00}
0xB1EA1 One Of: BIOS Lock, VarStoreInfo (VarOffset/VarName): 0x17, VarStore: 0x5, QuestionId: 0x7A8, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 67 09 68 09 A8 07 05 00 17 00 10 10 00 01 00}
0xB1EB2 One Of Option: Disabled, Value (8 bit): 0x0 {09 07 54 00 00 00 00}
0xB1EB9 One Of Option: Enabled, Value (8 bit): 0x1 (default) {09 07 53 00 30 00 01}
0xB1EC0 End One Of {29 02}
0xB1EC2 End If {29 02}

FPRR : 0x612

BIOS Lock : 0x17

These Variables have to be modified changing values from 0x01 to 0x00 searching for this GUID

(PchSetup) {24 1F F1 B7 70 45 E8 AD 43 49 8D C3 40 64 72 84 23 84 05 00 61 06 50 63 68 53 65 74 75 70 00}
---------------> <---------------------------------------

F1 B7 70 45 E8 AD 43 49 8D C3 40 64 72 84 23 84 >> (Little Endian) F1 B7 70 45 E8 AD 43 49 + (Big Endian) 8D C3 40 64 72 84 23 84 >>

45 70 B7 F1 AD E8 49 43 8D C3 40 64 72 84 23 84 >> GUID: 4570B7F1-ADE8-4943-8DC3-406472842384

Let me know, what do you want to try ...

Impossible to read the bios with the hardware... I try on other board with success but not on this one.
Maybe it's better to try with software solution if it's possible?
Thank you :)

You need to get all your DMI Data ... You got them ?

in example ...

Model name: 81FB
MTM: 81FB005URM
Lenovo s/n : YD04KB1H
Factory id: GXSC
WMAC: 505BC2BFCFB5
UUID: 505BC2BF-CFB5-2018-0604-141158000000

Otherwise i can give a Firmware to flash and get these infos , but differents ...
Let me know

@Tiripstruk

You should be able to correct the entries using the LVar tool. Grab it from here.
