Hi all, I am also in need of flash dump for this device, as the flash chip was dead and after installing new image on a working NAND device, the CFG/EEPROM partitions are empty and device boots linux, but the configuration interface is unusable.

many thanks for sharing. Unfortunately I read your suggestion too late as I have already set up the machine and no longer able to tweak with it.rex98Hi [USER="457801"]rex98[/USER]

Hi again,

after numerous attempts to recover the known passwords from the above experiment, I finally gave up trying to unlock the old BIOS.

Since the original problem I faced was that the network adapter would not start (Code 10) after a clean bios reflash, I though the GbE section may be the culprit for storing valuable init data, as well as the MAC address. So using the trusty CH341A and the [URL="https://github.com/LongSoft/UEFITool/releases/tag/0.21.5"]UEFITool 0.21.5[/URL] , I first extracted the original GbE section and then replaced in in a clean BIOS...

Hi again,

so I've been doing some digging, mostly reading thru the forum and browsing the dumps using the EFITool.
From what was mostly hinted, the AMITSESetup holds some information related to passowrd. However, the I don't know how to interpret the hex section.

I then tried flashing a clean flash image of a newer version (J01_0221_clean.BIN) and then booting and setting a password. I then read the flash chip again,...

Hi,

recently I got an old decommissioned HP Compaq 6200 SFF PC. Unfortunately, it had a password-protected BIOS, preventing me from installing a fresh OS.

I decided to dump the flash straight away (therefore desoldered the chip and added a botched socket so I can do easy experiments).

Hi,

Nice to meet you all, seems this place is quite vibrant.

I come from Bulgaria and I am currently employed in a semiconductor design company.
Usually I do analog design, but I also enjoy repairing old hardware and giving it some extra exploitation mileage. I do not own a repair shop and all repair efforts are either for a friend request, or for my personal fulfillment....
