Motherboard: Intel 6321ESB Southbridge
Skulltrail 6321ESB Southbridge
Since the Skulltrail system is based on a workstation chipset, it also uses the corresponding workstation Southbridge. Intel's 6321ESB connects to the 5400 Northbridge either via four PCI-Express lanes or four ESI lanes. The following table compares the normal ICH9 Southbridge to the 6321ESB.

A floppy controller is provided through a third-party I/O-chip connected to the Southbridge through the PCI bus. Intel's D5400XS board does not provide a connector for a floppy drive, however. We did not have any trouble updating the board's BIOS with a bootable USB thumb drive.
