Reference Boards are quite different from the production boards that will ship with the Reference Board chipset. While certain component arrangements may be retained from a Reference Board, we are evaluating a board designed for testing and qualification, and generally not for production. They are also normally designed to be tested on the bench, out of any case.

With 2 SATA Ports, 8 USB 2.0/1.1 ports, Dual-Channel Memory support, ATA133 IDE, 10/100 Ethernet-v.90 Modem, and the higher level 6-channel 2.3 AC'97 coded support, the ATI 9100 IGP PRO with IXP320 Southbridge compares favorably in features with Intel 865/875, SiS 655TX, or VIA PT880. There is no Firewire on the chipset, so Firewire must be added with an additional chip or a PCI Firewire card. Our Reference Board had Firewire Ports added with a VIA Firewire chip.

The 9100 IGP PRO does support SATA RAID capabilities. The IXP 320 southbridge on the Reference Board supports 2 SATA drives, while an optional IXP 400 southbridge will support up to 4 SATA drives. IXP 400 is aimed more at manufacturers who would use the RS350 in a high-end motherboard. Designers of high-end 9100 IGP PRO boards can also add additional drive support and RAID capabilities with additional chips.
