Getting bios files without windows

[Martijn_Weterin]

I wish to flash the bios on a hp envy 15 1170ez. The current insyde bios version is f2.b

I am trying to get the bios file for this laptop but everything that I find leads to a softpaq setup program that only runs on windows.

Is there a way to manually obtain the bios files?

Hi:

There is no way that I know of to extract the Binary files out of the HP consumer PC BIOS files.

I have tried disassembling them myself.

You can only get the DOS based flash files for the HP business PC's.

Wow what a quick response.

The 'DOS based flash files' that means the executable files for the setup program like insydeflash.exe or the .bin files that are to be placed on the disk?

Where could I find those bin files?

That is correct.

Like I said, I have downloaded the BIOS files for some consumer notebooks and there are no BIN files to run in any other mode but the supported windows operating system.

You can see for yourself by downloading  and installing the free 7-zip file utility from the link below.

http://7-zip.org/

Then download but do not run the BIOS file you are interested in.

Right click on the BIOS exe file you downloaded and select the 7-zip file utility to extract the files to a folder.

I cannot make heads or tails out of the files that you get but you won't be able to run them in DOS.

Many sources on the internet tell about extracting the .exe executable and using the resulting files.

.

I could already extract the file from the hp ftp server once but only got another executable (a file starting the InsydeFlash settings program). Extracting this second executable did not result into any files.

.

The 7-zip extraction programmed solved it for me.

.
Using 7zip instead of using AZarc resulted in a bunch of files that I did not see before. In my case there are two .fd files among them, I hope they can help me further. Probably some settings with the AZarc extraction program or maybe it is not able recognize the type of compression.
