Pros: Removable BIOS chip Great Linux support in RHEL / CentOS Rock stable performer

Cons: "RAID" drivers are in Win only, Linux requires MWADM software raid Updating from the 20x BIOS to the 402 or 404 BIOS resulted in the second SATA controller no longer being functional. :(

Overall Review: This board worked great with a pair of Opteron 8220 procs for over a year. When I went to upgrade to a pair of 4 core 65nm opterons I needed to update to the 404 BIOS which resulted in the 2nd SIL SATA controller no longer working, resulting in a server that fails to POST if both SATA controllers are enabled! Still fighting with the box, and will try a PCI-X SATA II controller card to get the box back online, but that SERIOUSLY sucks if you intent to use the new Opteron parts on this (otherwise terrific) server board.
