                              Hello there,
                              I have a SF314-41 motherboard that i bought impulsively recently, the problem is that i only bought the motherboard only, nothing else. When i tried powering on the board with 19V (soldered on the DC IN port), and then shorting the pin 1-2 of the keyboard, the board is turning on (as indicated by the fan), however it seems like the board is displaying on the internal display as connecting to a display on the HDMI (external) does not display anything.
                              I tried connecting a USB keyboard, the keyboard is powered on, however pressing numlock do nothing (supposed to toggle...

                              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...

                              This laptop is the same laptop I was working on in this thread and I wasn't sure if I should post a new topic or post in that thread because I already solved the issue that thread was discussing and this is a completely different issue although it is dealing with the same laptop. I decided to make a new thread since it's a new issue, but please move if I made a mistake.

                              Who has a MSI Z590 PRO WIFI - Need BIOS dump ?
                              by DynaxSC
                              Hi,

                              I need a BIOS dump for MSI Z590 PRO WIFI from a real physical board, along with MAC address and serial no.

                              It must be a dump from a physical board, as it contains personalized data eg. MAC Address, UUID, Serial no.

                              I have a board which has lost the BIOS contents, I have the MAC and serial to this board, and need to insert it into the another BIOS image. To do it, I need to have a real image from a real board, as the images from the MSI site are without this data. The only way to find where MAC/UUID/Serial is located in the BIOS is to have a bios...
