It implements secure boot which can help prevent malware from hijacking the boot process. There can be enhanced boot speeds and some even provide Internet access and games. The BIOS firmware is stored on a serial flash chip on the motherboard. Fortunately the chip is socketed so no soldering is required. Otherwise, if the chip is soldered there may be a SPI header on the motherboard.
Please see my previous tutorial for SPI programming and desoldering instructions. A small screwdriver works well for removing a socketed chip. The blade goes between the chip and the socket. Avoid trying to pry the chip up because the screw driver could scratch the traces on the board. A safer approach is to twist the screwdriver blade. Take turns lifting the chips from opposite sides and only lift a little at a time.
If you lift one end of the chip too high it can bend the pins. Of course, a Raspberry Pi would work too. The chip is placed in the programmer with the notched end aligned appropriately. The lever locks it in place. The programming software that comes with the programmer works well. Click Device Read — Read. The BIOS firmware on the chip should load into the buffer. Please make sure you keep a backup copy of the original BIOS just in case something goes wrong.
A couple of open source tools are required to work with the UEFI files. Both tools are available on the LongSoft GitHub page. The second tool is FD44 editor. Unlike my previous tutorial , the downloaded BIOS file is a capsule and needs some work before it can be programmed to the flash chip.
Run UEFI tool. Click File — Open Image File. Most often it results in a crash to blue screen. So when using the EX3's USB port, I always make sure to shut down and unplug the device before shutting down the computer. This must be set or all of my USB 3. Thunderbolt Issue: Device recognition Solutions: Contrary to earlier firmware versions of this card after the latest firmware update NVM Originally I had to make sure my devices were connected and powered up before turning on the system, now that seems to lead to instability, and sometimes outright failure to detect any devices.
No issues to report. It all seems to function as expected. I only use the startech converter, i read somewhere? It was awhile ago. If i try to plug in a device after computer starts i get a lock up, so i dont bother. I have more problems with thunderbolt 2 devices on one system than another system i have, Lately. It is a hit and miss , mostly problems starting up, but after it is up nothing usually. I have this board and thunderbolt 3 working no problems. Originally Posted by hellokitty.
