Bios Mods -The Best BIOS Update and Modification Source

Hi guys. Is there any chance to find supervisor password in dump files from IdeaPad Y580. Bios version is 5DCN40WW (2.07) - Insyde bios. I`ve got two .bin files, one is 4 mb and the other one is 2 mb extracted from dual bios ( winbond ) chip on my motherboard.

Let me know

From Schematics It would be an W25Q16BV 2MB + W25Q32BV 4MB :

http://www.s-manuals.com/notebook/lenovo_ideapad_y580


Expaination :

Lenovo IdeaPad Y580 FPT -d ... -bios

W25Q32BV 4MB 1st ---> 4096 KB +
W25Q16BV 2MB 2nd ---> 2048 KB


W25Q32BV 4MB 1st ---> Starting Offset FullDump Firmware 6144 KB = 0x00000000 physical address
W25Q16BV 2MB 2nd ---> Ending Offset FullDump Firmware 6144 KB = 0x00600000 physical address


This Fimware has two chunks and start into 1st Chip, these the Offsets :

0x00000000 - 0x00600000

0x00000000 - 0x00001000 = Descriptor Size 0x00001000
0x00001000 - 0x00180000 = ME (GbE) Size 0x0017F000
0x00180000 - 0x00600000 = BIOS (PDR) size 0x00480000

So Bios Firmware is splitted into two chunks :

1st Chip from 0x00180000 until 0x00400000 End of 1st Chip then continue into (Size 0x00280000)
2nd Chip from 0x00000000 until 0x00200000 End of 2nd Chip (Size 0x00200000)
Total (size 0x00480000)

The EC firmware is allocated before Bios Region and usually into 2nd Chip when It is 4096 KB.
In your case is into 1st Chip before Bios Region.

To Replace Bios Region using one Original (You will loose DMI Data) It's enough to get the Chunk
from a Bios Backup or Original Bios reading It by UEFITool (CodeRush).

I sent in PM your Re-Generated files !!!

Hey man, the winbond chips are W25Q32BVSIG - 4 Mb and W25Q16CVSIG -2 Mb. Thank you for helping me with this. I will let you know in following days when I flash these .bin files if I bypassed the password.
