Re: bios dump elitebook 840 g3
Hello, Anyone willing to share the bios file for the ellitebook 840 G3 which is 8MB? I have an empty read in my rt809f. and obviously I don't have any backup.
I have tried from several files that I can find in this post, But nothing works.
Notes.
- Bios still reads fine as
- General Plus - MX25L6405@SOIC16, capacity: 64Mbits, 8Mbytes.
- blank chip reading
Some of the writing experiments conveyed the message:
059: Chip ID verification OK.
060: Start writing chip......
061: Auto erasing...
062: Erase successful£¬Elapsed time£º19.53 seconds¡£
063: Start writing...
064: Write successful£¬Elapsed time£º106.7 seconds¡£
065: Auto verifying...
066: Chip verification error, start position: 0x1000.
067: Verification failure£¬Elapsed time£º0.162 seconds¡£
068: Status register1 values: 0x40 ¡£
069: Write error, operation terminated.
Best Regard

I've tried several times with dozens of 8mb bios files I got on this forum. But all display the same error message.
So can someone tell me what's wrong here?

Bios code - MX25L6473fzni
Does it affect my ISP method? I mean, does it have to be completely removed from the board to flash? While this can detect the chip well on the ISP method.

Not @SOIC16.

Not @SOIC16.
in the rtf list many choices only mention @SOP8 / @WSON8 / @VSOP8 and there are also some lists without mentioning them all, only sincere MX25L6405
which one should I choose for some of these lists?
I've tried to select @SOP8 on flashing it worked, but laptop still not working!
In advance, thank you very much to all who have provided feedback here. Very much appreciated.
Thx

Re: bios dump elitebook 840 g3
Choose sop8, your laptop has a 16MB chip and an 8MB chip, you have to flash both these chips synchronously. Remember to back up your chip's original file before doing anything.

and I think it's a development because laptops give a sign of life. but unfortunately it's still no display and the fan is spinning fast.
I think now the problem is in the bios firmware itself.
so i now need bios files for 8mb and 16mb, if you will share for me, much appreciated. Because I have a lot of mixed files. And the original copy is missing.
