Hi,
Is there a utility to open bios cap files and edit them or just look around ?
Thank you
It's not for a particular PC or BIOS. I just want to learn more about the UEFI BIOS and manage to edit them or lookd for problems . I have experience with the classic BIOS files but for UEFI just theoretical information's. I just want to practice and when i will have to deal with a broken UEFI or something else related to UEFI i will not be caught off-guard !
Thank you very much for your kindness and information's, you're great.
Thank you very much for all your effort. I will check the tutorials and the tools you listed here and slowly try to understand the differences and the way UEFI works.
Thank you very much.
I kept on studying, but i feel like i need also some practical experience...i can't wait to get my hands on a motherboard that uses UEFI
or better a laptop to try and unlock certain features, but none until now.
However i am also interested if there is an Award tool for their UEFI BIOS'es ?
Is there such a tool like the Ami Aptio 4.55 tool ?

I would appreciate that very much indeed.
The machine is a Dell laptop/notebook: XPS 13 L322x
the bios updater on the Dell site is an .exe file. When you run the .exe on a dell, it flashes the bios. When you run it on another machine, it complains with
ERROR 255 - You need Administrator privilege to proceed to the BIOS update.
and you can only click the "OK" button. There are no files to review.
However, the first thing that the .exe does is extract files to %username%\appdata\local\temp\ExtractTemp\, and they are there while that error dialog is on the screen. SO either copy them at that point, or kill the app with ctrol-C you will have the following files in ExtractTemp:
BIOS.cap
default.rsp.bak
DosFlash.exe
SctWinFlash32.exe
TdkLib.sys
TdkLib64.sys
WinFlash32.exe
WinFlash64.exe
and default.rsp.bak is a text file which has the following contents:
------------------------------------------------
/nodelay
/silent
/bbl
/cvar
/file BIOS.cap
------------------------------------------------------
Does this mean that I should flash the .cap file directly? What would be the correct procedure to unbrick a dell laptop with such a Bios?
I note that running DosFlash.exe on my other machine gives an error about an "Unsupported 16-bit application".
However, SctWinFlash and the two WinFLash exes are all signed by Phoenix Technologies - so does that mean I have to "do something" to extract a .WPH or .ROM or .HDR file from this .cap file?
From what I've read about Dell phoenix BIOS files, you run the .exe with /WriteRomFile and /WriteHDHFile options to extract those files -- but as far as I could tell, they do nothing in this case. But maybe I was looking in the wrong place??
the list of options in the default.rsp.bak file point out something I have't read about before:
do I need to include a file like that on any crisis flash floppy that I make if I want to flash the "whole" BIOS?
Will the /cvar option ("clear variables") also clear any BIOS password that might be present?
Rather than upload the .CAP file, which is 13MB, I will upload a .rar achive of the original .exe file as downloaded from dell. So Unrar it and then run that .exe to get the .CAP file in your %appdata%\Local\Temp\ExtractTemp directory
thanks for any help you might be able to give
If the laptop it's bricked then the only solution it's to directly flash the bios in an external programmer. If the laptop still boots or it's able to boot from an USB drive, then you might try with DOSFLASH.EXE which it's a pure DOS application, impossible to execute in a command prompt window under windows...

So did you ever manage to extract the images from the CAP file or get the bios-files another way? I have a few L322s boards which I would like to fix :
