Created attachment 239283 [details] Error screen I bought several, the same model new motherboards from Supermicro. Motherboard model: A3SSV-24C-SPLN10F It is a new motherboard with Intel Atom P5362 and it has legacy bios option removed completely. When I try to install the system, I get this error: Mounting from ufs:/dev/ufs/FreeBSD_Install failed with error 19. Please see attached screenshot for full error screen. I tried to install the system with several USB Flash Disks, USB DVD Reader, SATA DVD reader, mounted installation image through BMC, but the result and error stays the same. I tried different versions of FreeBSD (12.4, 13.1, even 14.0), also tried different operating systems based on FreeBSD (TrueNAS, opnsense, NomadBSD) and the error is the same. On the other hand, I install and boot any Linux distro the same way(Rocky Linux, Ubuntu...) also Windows 8, 10, 11 on the same motherboard without any problem.
