Lenovo ideacentre 310s-08asr bios problem

[MikeBaxter]

Hi, i read more guide to extract the bios bin from the installer...but nothing.
i use the innoextractor but with errors:

Not a supported Inno Setup installer!
Done with 1 error.

i download the installer (o2hjy63usa.exe) directly from lenovo support with the PC serial number:

https://support.lenovo.com/it/it/dow...tre-310s-08asr

the flash on the mobo is a MX25U6435F.

my question is how can i extract the bios??
thanks a lot for your help

Use 7zip.

Okay, I tried to extract files directly from the installer using 7zip, but I get many large 64Mbit files. When I try to compare them with each other using a hex editor like Neo, they are all different from each other. So, which one should I use? The files are of the following types:

• IMAGEO2H.rom
• O2H3X.rom
• 310/O2H3X
• 310/O2H3X.rom

All are 8192kbytes in size (i.e., 64Mbit), but none are file.bin.

There are 2 files: IMAGEO2H.rom and O2H3X.rom equivalent to two bios.
Do you have experience building bios?

[MikeBaxter]

This is an incomplete bios. Before doing this, you must backup the bios and always remember to back up the bios successfully.

i haven't a backup, because the pc don't start, infact i want to program the flash directly with a CH341a (with 1.8V mod).
but, this is how i read from the flash

Ok, so from my dump you say it corrupted?

When I try to write the flash, I have all time an error on 0x00020040, so I cancel the flash 4-5 and I try again to write IMAGEO2H.rom...success.

Thanks for your help.
PS before to open this thread I search and search for a solution 😅

thanks friend, I flashed the bios as you attached it but nothing to do, it doesn't work.
Monitor always black and if I try to remove the RAM the buzzer doesn't beep
