After working surprisingly well for several days, my new GA-D510UD hung first during its check of DMI pool data then immediately after when I swapped the DRAM. I am running the F4 (current) version of the BIOS. I read other suggestions that the chipset driver be updated but as this is loaded at boot in Linux I do not understand this approach as a promising solution. I am comfortable that linux is not a supported operating system, but I need to sort out this issue before any O/S can be installed. Most likely unrelated, my first issue arose after a failed attempt to install lvm on software raid5 (mdadm). Are there any suggestions to enable this board load an O/S. I like this board very much but it needs an operating system.
