Lenovo Flex 10 Bios help

[Antiklesys]

Hey man I have your same issue.
Do you have any links to bios 93cn27ww ???

[Antiklesys]

I'm triying to put the 93cn27ww on a laptop to replace the 32 bit 93cn19ww bios so i can switch from UEFI only to legacy support.
Any hint? Also I can't seem to find 93cn27ww
I have 2x Lenovo Flex 10 one with 93cn27ww and one with 93cn19ww
Any guideline is appreciated here too

You could make backup of v27 bios from inside flash chip of one Flex10 and flash into another.

The universal bios backup tool for this can be found on this site.

If you can also upload the v27 bios backup file I would appreciate it.
I'm trying to find older version on which I can install Win 7 again.

I know there must be someone out there still having the older versions of bios running on their Flex 10

93cn50ww, 93cn28ww, 93cn27ww

Please help, either a lenovo flash .exe file or chip hex backup would be nice

Hey thanks for the advice.
I'll give it a go and try to upload the result here

Also, how do you suggest to use the extracted file to flash it on the other PC?
That process is not 100% clear to me. Do you have any additional insights?

To get the bios file from the chip, you can use "Universal BIOS Backup ToolKit 2.0" program

also you can use Intel Insyde h2o platform flash tool "fpt.exe", but you have to find a version that supports your chip


To flash that file into another laptop you can use fpt.exe again, or a hardware flasher with soic 8 clip if fpt.exe is unable to unlock the flash

Is there a way to extract .hex file from .fd file?

I got it, need to edit .fd by hex editor and remove everything before (and including) "$_IFLASH_BIOSIMG..€...€." on 1C1E0h at beginning of file and everyting after and including " _IFLASH_INI_IMG" at 81C1E0h at end of file so file has same size as flash (800000h)

So I can get back the 32-bit bios now.

Still looking for version 93cn50ww (last 64 bit bios that runs Win7) if somebody has...

My Bios version is 93cn50ww. My bootable USB starts but after reboot laptop is freezing
