    How do I flash the original BIOS back? I took a backup with the BACKUP TOOL and it created a file named "Dump.rom". When I run the Insyde flash utility to update, it says it can't find the ROM file in the directory.

    Hello Pyr0,

    Would there be a way to flash the Serial Number based on this mod? I'm using a VPCSB.

    Check the filename in the .ini file (it has to match your backup when you want to flash it) and copy your dump.rom in the flash tool folder.

    The serial number and other machine info like service tag# and model number will not be touched by the hacked BIOS upgrade. That means that if you are running on a stock BIOS, your serial number and stuff will be kept as it is.

    I copied the DUMP.ROM into the flash tool folder.
    In the "platform.ini" Under [FDFile] I changed to FileName=DUMP.ROM
    When I press START in the InsydeFlash utility, I get an error message "Load file: File may not have EC rom!"

    I propose that anyone messing around with the modded firmware post their experiences here, as to encourage or prevent others, so we all have a collective experience.

    For my part I'm using the firmware but've been very careful as to touch too much since the reports on the bricked machines. So far I needed a way to change the SATA mode from IDE to AHCI forth and back (to test deployable systems) and that's about all I've done and it works fine. I'm tempted to change the LCD resolution to 24 bit (it's defaulted at 18 bits) to see if that will improve the not-too-impressive display, has anyone tested this setting?

    Had anyone tried modding an SA4?

    Hey Pyr0,

    I bricked my BIOS, but I'm able to manually flash the BIOS. The BIOS dump and and the original file contain three parts with the same sizes.

    How to do it right? Can I directly flash those parts? Or are the settings stored in other regions.

    Can someone give me a full dump of a working BIOS (R2085H4) to make a diff with mine.

    Someone else helped me out, but thanks anyway!
    Now I have a kind of BIOS dongle :p
    Easy to remove and flash, if something gone wrong.

    +1

    Are you interested in testing SATA3-reenabled S-Series BIOSes?
