Tyan joins the AMD 6-core release cycle with “Istanbul-enabled” BIOS releases six 2P motherboards (and related systems). We here from a reliable source that the Tyan “twin” system (B2985, 2-node, 1U) BIOS is in “alpha” testing and will be released “soon.” Here’s what’s available now:
Dual-Opteron Motherboards (2000-series)
These BIOS releases were only available from Tyan’s FTP site (ftp.tyan.com, anonymous access) until now. As of 6/17/2009 you will find them on the BIOS helper from the product web page.
Also, we were surprised to find that the AGESA for the S4985 series (quad-socket) motherboards are still version 184.108.40.206 and are likely not Istanbul-ready. We do not have the S4985 in our testing lab to confirm of deny this, but we have been told by AMD that 220.127.116.11 is the minimum Istanbul supported AGESA.
