Hi there, TLDR: I'm pretty sure the BIOS is corrupt and a new one needs flashing. I'm looking for a BIOS download link for an ECS B150H4-EM_DDR4 S1151 IPO V3 (MSN: 2006 3015). I've seen a couple of very helpful superusers/mods on here supplying these to others in similar situations and would be very grateful if they could come to my rescue too (I hope you don't mind the tag @daddle ). Much appreciated! Long version for context: I have an old Akoya P5370 E (MD 8866, MSN: 1002 1376). The motherboard model sticker says B150H4-EM, and the MSN sticker next to it is 2006 3015, which matches the motherboard listed on the P5370's product page, where it is listed as "MB ECS ECS B150H4-EM_DDR4 S1151 IPO V3". I turned the PC on yesterday after a long time in storage and an even longer career as a Linux based game server. Discrete GPU is absent and all drives/devices have been removed for the purposes of troubleshooting. Initially, the PC would fail to boot and remain stuck on the Medion splash screen. This was from the linux server's 2.5" SATA boot drive. After removing and replacing the cmos battery and disconnecting the 2.5" drive, I got it to boot from an Ubuntu installation on a usb stick, with no other drives installed, and everything worked fine. I then shut it down, removed the usb, and added the original m.2 SATA boot drive that shipped with the PC and, as far as I can remember, still has the original Windows 10 installation on it (though the rest of the drive has been used for other data storage since). It failed to boot, and stayed stuck on the motherboard splash screen again. I turned the PC off again, and reinserted the Ubuntu USB. When I tried to boot it, it eventually landed on a black screen with the message "(A7) Me Downgrade - Request MeSpiLock Failed". I have since removed the m.2, done the battery reset twice, and jumped the CLR_CMOS pins once, but no subsequent boot attempts are able to output any display signal at all (CPU and PSU fans do spin, and power LED is on). I looked up the "Me Downgrade" message and the results suggest the bios is corrupted and needs to be flashed. After a fair bit of fruitless searching, I found a thread on here where the link for the V2 version of the same MB was posted, and I'm hoping for the same resolution. Thanks to anyone reading this for your time and attention. It's very cool to find such an active community that still supports people with these older devices. Cheers
