I have supermicro X7DWE motherboards here. PXE works, yet the bios of the motherboard doesn't allow Mellanox QDR cards to be booted here. See supermicro website, they just fixed 1 type of bios for that for 1 specific motherboard in that series and that isn't the X7DWE. At boot time it always switches to the intel firmware that's inside and boots the internal gigabit ethernet adapters. > * if PXE server with Infiniband is impossible, then it is OK with a > gigabyte connection?
