Hi all,
I just put the second CPU and maxed the ram on this board for a DB I'm running. Powered on, went fine, cheched a few things in BIOS, and disabled BMC (boot was just too long). Powered back on and all was fine, but I )stupidly) decided to start fresh and clear CMOS. At this point I lost USB connections. So no keyboard or mouse, can't get back into BIOS. It looks for a bootable drive (which is a USB stick) but fails. Any thoughts on how to get USB back online? I'm guessing there's the XHCI handoff seeing in BIOS or something - but can't ge there. Any help?
