Hi,

the situation:

I get a laptop with bad bios (mostly DELL).
Then I try to find and download a suitably ROM-File for that BIOS.
Next I solder out the BIOS chip and read it in an external programmer.
Sometimes in the new BIOS there is a Windows key included - so I overwrite the key with the one from my BIOS-extraction.
Then I reprogram the chip with the BIOS I found here.
In most cases windows is working with my original key.

But the most ROM-Files contain no windows key.
And later if I check in Windows I...

Re: Dell 15r 7520(5520) bios dump needed



I have to write the 2MB EEPROM in an external EEPROMER.
So I need only a part of the FD-File.
In the FD-Files there are both ROM-File included.
The 4MB and the 2MB.

Is there a way to extract both files out of the FD for using in an EEPROMER?

Or can I split the FD at a special position.
I think somewhere in the FD-File there should be a pointer to the 4MB and 2MB ROMs (or the pointer is in the INI-File which is included in the compressed EXE BIOS-Update-File)....

Re: Dell 15r 7520(5520) bios dump needed

Hi together.
I would also need the 2MB BIOS DUMP for the Dell 7520.
Same problem.

Is it possible to extract the ROM Files out of the QCL01A11.fd?

Re: dell inspiron 15R 5521

Sorry for my stupid question?
Do I have to flash both files?
The 2 and the 4MB?
So I have to resolder both chips?
