Sorry I didn't explain it very well, the backup I have is the one from the bricked bios image which means that this backup have missing or damaged code if I flash this backup to the bios chip I'll have the same problem as before a black screen and nothing else, this same backup contains some code that normal bios updates don't have as they only update a part of the bios and I want to merge these two files using a Hex editor . to be clearer it's has been done here

here are the files compressed in winzip (these unpack with no problem)

Hi prema!

I found a complete backup of the Spi flash that I did earlier (before I erased the SPI completely) and I was thinking if you can help me reconstrut a bios image merging the backup I did and a new bios image sent from the vendor. I just don't know what offsets should I keep from the backup and what offset should I copy from the vendor bios file to merge the two and have a working bios image.

My laptop is still not fully operational and yes I still need that Bios Dump, I'll be waiting for your help.

Anyone please !!!

Both version windows and dos don't work, I keep getting the same message as before .

I flashed Sager bios in despair, the only behavior change I noticed is that the Cpu fan spins at boot and then turns off after some seconds.

I recently recovered from a bad bios update, I had to erase the bios and to reprogram it using a Parallel Port SPI Flash Programmer, now there are certain functions that doesn't work, Cpu fan doesn't spin // 4 Go of ram not fully recognized // Ctrl+Alt+Del shuts down my laptop instead of rebooting it.

So now I need someone to dump the whole bios chip for me using pure DOS using FPT and I'll flash it to my laptop.

I attached the necesseray files (Given by Prema) to do it , at DOS type STEP1 (it may reboot your pc ) after still in DOS type STEP2 and you will have a file named backup.bin you can upload here.

I would suggest to get someone to dump the whole chip for you from an identical working model in pure DOS via fpt and flash it to your system with the same software.

The version of fpt you provided doesn't work with my laptop(South Bridge: Intel Ibex Peak-M PM55), I'm looking for a comptabile version before I ask anyone to dump their chip for me.

I can't find anywhere a version of FPT compatible with my laptop w870cu, does anyone have a link to it ?

Here is the service manual for W860CU and W870CU

Hi Prema, I had a bad exprience flashing a bios to a Clevo W870cu which ended with a black screen and I have succesfully recovered from it using an Spi Flash programmer which I made myself reading some tutoriels on the net, while reflashing the bios I had to erase the ship before I could reflash the correct bios, now I can boot normally but later I realized that I wasn't completely recovered as I'm left now with the following problem :

1 - The Cpu fan doesn't spin at boot nor when I'm in windows 7, the only way to make spin(it spins slowly) is to press the silent button

2 - I have 4 Go of ram and only 3,60 Go is recognized now by the bios and windows 7 sees the 4 Go but only 3,60 is usable

3 - When I press Ctrl+Alt+Del at boot the pc doesn't reboot but it shuts off

4 - I Had a warning at boot saying that "ME FW Update Failed,Please Try again!" I reflashed to the latest EC and Bios version and it's ok now.

can you please tell what I did wrong and was it the fact that I erased the ship with spipgm that deleted some blocks that normally not accessed by the official flashing program given by clevo???

any suggestions is welecomed.
