![]() ![]() I disconnected the Vcc lines, and only left the ground reference. I surmised maybe the board has other stuff connected to the 1.8V line which the TL866CS cannot power. So, next up, tools needed: my venerable MiniPro TL866CS programmer, an 1.8V adapter, and some sort of connector that has a 2mm pin pitch (I used an interconnect out of a broken-up LCD TV) First try, got the usual "Overcurrent Protection actions" failure. ( !tabs=1-8V128Mb) Operating voltage is stated as "1.65V-2V", which I confirmed with a multimeter reading of 1.8V on the power pins. I have to declare, most of the idea came from this site, where I was looking for a pinout ( ) What I find amazing is, the Japanese chap had a board that had a 3.3V Winbond BIOS on it, but mine uses a MX25U12873F chip - which is thankfully documented on the Macronix site. Plus, MSI is so nice they provide an undocumented but populated SPI header (JSPI1). Now I realize it would be probably possible to return the board, ask for one with a newer BIOS, but daddy didnt't raise no pussy. Not sure how this is supposed to work, as with these new generation processors, more and more functions are integrated into the CPU (when did we wave goodbye to the Northbridge? 2009? The Southbridge is going away soon, I fear) - nevertheless, if it is possible, then not with this board. There is info on the net of supposedly copying the new BIOS onto a blank USB stick, doing a BIOS reset, then turning on the MaBo with the USB stick plugged in, and it automatically updates. But how to update a mainboard that simply lights the "CPU" EZ-Debug LED when you plug it in. To me this means either BIOS 7A37v1B or newer (it's from Jan 2018, and has this in the release notes: "Update AGESA Code 1.1.0.1 to support Raven Ridge CPU") Of course I wanted to use a Raven Ridge to be able to go without a PCIe GPU. ![]() Note: Do not remove USB storage drive when flashing Bios and system will auto reboot after bios update reached 50%Īfter auto reboot, system will start updating Bios ME, please do not remove USB storage drive or shutdown the system.Īfter finish updating BIOS, wait for 5 sec then the system will automatically reboot.Hi, just a short one: Amazon in Germany sells this Mainboard with the BIOS version 1.2 (7A37v12 in MSI-speak, from April 2017) Problem is, if you want to use a Raven Ridge APU, you need a fresh BIOS, as Raven Ridge was introduced in October 2017.
