[QUOTE="rsaeon, post: 2383431, member: 76792"] So I've finally got a few of these to play around with. I have a few long-term use-cases in mind but for now I just want to explore the hardware since a platform like this is extremely rare. The last time we had a quirky platform for computing was with AMD's AM1 in 2014 and there has been nothing in between then and this 4700S Desktop Kit. (maybe 2016's Athlon X4 835/845 would count, they were mobile processors in a desktop package) [ATTACH alt="4700s-desktop-kit.jpg"]140594[/ATTACH] One of the boards had the original C04 bios, so I flashed a UEFI shell using Rufus with a GPT partition map in the recommended ISO writing mode (not EFS) onto a USB2 drive. I found the UEFI shell here: [URL]https://github.com/pbatard/UEFI-Shell[/URL], Rufus is at [URL]https://rufus.ie/en/[/URL] and the BIOS files at [URL]https://www.amd.com/en/support/desktop-kit/amd-4700s-desktop-kit/amd-4700s-desktop-kit[/URL] I copied over the BIOS folder C0A from the extracted zip and powered on the desktop kit with the USB2 drive plugged into a USB2 (black) port. Flashing directly from C04 to C0A was pretty straightforward: [ATTACH alt="bios-flash-procedure.jpeg"]140595[/ATTACH] But for this, there was no auto shutdown as mentioned in the PDF that's in the bios zip or the command line switch in the photo above. I reflashed one of the other boards to C0A this way and that one did shutdown down after completion. The time from power-on to display output has increased by a second or two with the C0A bios compared to the C04. I took some preliminary power consumption readings with a fire hazard of a smps that I have for testing (it draws 8w with nothing plugged in) and it was under 100w at idle and peaking under 160w (145w average) while flashing. The readings were the same before and after bios update. Those are pretty horrible numbers but I think most of that is from the inefficient power supply. That's it for now. [/QUOTE]
