    OEM Bios crossing

    Quick question:

    Is it possible (via BIOS updates or BIOS chip swapping) to convert an OEM board, such as the Board from a HP XW9300, to the clone of the the board, in this case a Tyan K8WE?

    They're the exact same board except the HP one has one less LAN port and also has SCSI (suppossedly an option on the tyan's version).

    Reason I ask is i recently found a XW9300 board for cheap and I was really wanting a K8WE... and if it was convertible by way of a BIOS flash or fresh BIOS chip, then I'd go for it.

    You can on some boards, but that doesn't mean you can do it on all boards.
    I love putting bad caps and flat batteries in fire and watching them explode!!

    No wonder it doesn't work! You installed the jumper wires backwards

      In theory you can, but the boards have to be identical meaning all the IC's have to be the same... usually there are some minor differences between boards. Also, the flash software does a PID check before flashing and if the board is an OEM model it terminates the flashing process.

      What you would probably have to do for a successful bios de-nerfing is to desolder the bios chip and put it on a dedicated programmer to change the PID values. One other possible option would be to figure out a way to put bios chips in some sort of socket adapter and do a hot flash... had to do that a couple times in the past with some boards and it actually does work. Basically you boot up the PC off one bios, yank out the bios chip and replace it with the board still running. That way when the bios flashing utility loads it will read one bios, and right before it flashes you simply swap out ICs.

        there are some flashers that are dos based and you can use some kind of /f to force a flash

        I did such thing on an HP s939 board a year ago. bricked it good

            Another thing to consider is the General Purpose Input/Output (GPIO) pin usage on the chipset - the use of these pins is at the discretion of the manufacturer.
            My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

              The boards are literally the same PCB... Exact same PCB.

                I have one of those boards here somewhere, completely forgot about it.....it donated the IO shield to the Frankenserver way back when. That board has a few other differences as well, it has no case header for the buttons, lights, etc, the pins were never soldered in. You could put them in, you'd have to clear the holes and add them.

                FWIW, the HP BIOS has the same features and functions as the OE.....just has the HP splash, which you can disable.... I wouldn't worry too much about the BIOS.

                  by DynaxSC
                  Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).

                  I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...

                  by Tynan Dill
                  I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                  Upon bringing it home and plugging it up, it showed a standby light.

                  I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                  The screen seems to blackout and stay black, but with a flashlight I can see the display.

                  With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                  ASUS TP500LA BIOS request/repair/merge?
                  by jbonavita
                  Hi, my laptop wont boot at all
                  With original bios no POST, only LED lights
                  With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                  Some issues
                  A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                  B- If updated from 500LN version 203 to 300, the battery stops being recognized

                  Things I tried

                  1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                  [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                  by zenius
                  Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                  Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
