[Done] T43 Embedded Controller upgrade problem

[x3o2]

Hi there,

I want to upgrade my T43 2669 BIOS, so flashed the latest Lenovo BIOS first. Success.

Then I tried to update the latest Lenovo Embedded Controller firmware. This did not work, not with Winflash, nor Phlash16.

This tool quits flashing the Non-Dikette EC with the message 'Specified BIOS ROM file is not for this system'.


Last thing I can try is the Diskette EC, which is a self-extracting image (https://pcsupport.lenovo.com/de/de/oldd ... s/ds014006)

As I do not own a diskette drive no more, I have to emulate it.

WinImage, Virtual Floppy Drive and ImDisk I have tried, but the image file will not mount.

Can you tell me how to do that to get hold of the files the image contains?

Unless it's the same file, download this non-floppy version:
https://thinkpads.com/support/Thinkpad- ... hj06us.exe
Run it from within Windows.
Or try to extract the files from the floppy-version using: https://www.legroom.net/software/uniextract

Other program to experiment with and make a bootable USB: Rufus

Thank you for your answer.

Tried that, no success. Quits with an Eflash Error: 'DeviceIoControl() returns 24'

Or try to extract the files from the floppy-version using: https://www.legroom.net/software/uniextract

Tried that as well. File can not be extracted ('Filetype returned was: not a valid PE file')

Other program to experiment with and make a bootable USB: Rufus

I created a bootable USB with Grub4DOS and Rufus. Both work well, but flashing still does not.


Do you know a software to emulate a diskette drive with? With this I could mount the Diskette-EC-firmware and copy its files.

And put them onto my bootable USB to flash the T43 EC.

I linked the file to be mounted in the first post, feel free to give mounting it a try.
