On the storage side, this motherboard brings two ATA-133 ports and four SATA-300 ports controlled by the NF430 south bridge. Its SATA ports support NCQ (Native Command Queuing) and NVIDIA MediaShield RAID, feature that allows a RAID system supporting RAID 0, 1, 0+1, 5 or JBOD. This board comes with just one Serial ATA cable, one Serial ATA power adapter and one 80-wire IDE cable.
On its networking side it features an on-board Gigabit port controlled by the NF430 south bridge, requiring just a small chip to make the physical layer interface – a Marvell 88E1115 is used here. Its on-board networking features NVIDIA’s software-based firewall system, ActiveArmor Firewall. nForce 4 SLI XE has lost NVIDIA’s hardware-based firewall system available on its predecessor, nForce4 SLI Intel Edition chipset, which uses less system processing power.
As an optional item it is possible to have an extra 10/100 on-board LAN port, controlled by Realtek 8100C chip.
C19-A SLI has an eight-channel on-board audio (7.1 standard) produced by the south bridge chip together with Realtek ALC883 codec, having individual outputs for each channel pair plus optical and coaxial SPDIF outputs soldered on the motherboard.
This motherboard has eight USB 2.0 ports (four soldered on the motherboard and four available through I/O brackets) and can optionally have two FireWire (IEEE 1394a) ports.
ECS C19-A SLI comes with one CD-ROM containing drivers and several utilities.
