It seems like CeBIT is the place to be when it comes to spotting P55 motherboards, as on top of the two Asus motherboards and one model from MSI that turned up yesterday, pictures of another model from MSI alongside models from Gigabyte, Biostar and Jetway have turned up.
The second board from MSI is a higher-end model called G9P55-DC and it doesn't have any video output options. What it seems to have is some kind of PCIe splitter, like a PLX chip or nForce 200, as the motherboard has two large chips on in and as the P55 is a single chip chipset and with the board having three x16 PCIe slots plus one open ended x4 slot, this is the only logical conclusion. The board also has two PCI slots and one x1 PCIe slot which is meant to be used with a bundled sound card.
Interestingly, MSI has also added a pair of eSATA/USB 2.0 combo ports and the board also has 10 SATA ports, IDE, dual Gigabit Ethernet and a bunch of buttons at the bottom of the board. It's a bit unclear what this board really offers, but we'll try to bring you more details from the show once our team gets going later today.
The Gigabyte board is currently just called the GA-IBP and this board is ready for CPU's with integrated graphics as it has a DVI, D-sub and HDMI port, as well as two PS/2 ports, four USB 2.0 ports, dual Gigabit Ethernet with teaming and 7.1-channel audio jacks around the back. Other features include three x16 PCIe slots, two PCIe x1 slots, two PCI slots, six SATA ports, headers for three FireWire ports and eight extra USB 2.0 ports, a debug LED and power and reset buttons on the board. There's also support for CrossFire and SLI.
The Biostar board seems to be called TPower I55 and it has a pair of x16 PCIe slots as well as a x4 and x1 PCIe slots and two PCI slots. We're not quite sure about the port layout, but it looks like the board has two PS/2 ports, six USB 2.0 ports, FireWire, dual eSATA, dual Gigabit Ethernet and 7.1-channel audio with optical and coaxial S/PDIF out. The board also has headers for six additional USB 2.0 ports, a FireWire port, six SATA ports, an IDE and floppy connector and interestingly a Turbo Memory slot for Intel's second generation of Turbo Memory modules.
The Jetway board is called HI05-LF and it has three x16 PCIe slots, although the third slot is labelled HD display slot and we're not sure what this is about, although as the bandwidth would be limited, this might be what Jetway is trying to say. The board also has two PCIe x1 slots, two PCI slots, six SATA, IDE, a parallel port header and a Turbo Memory slot as with the Biostar board. Around the back it looks like Jetway has gone for a pair of PS/2 ports, optical and coaxial S/PDIF, a CMOS reset button, six USB 2.0 ports, dual Gigabit Ethernet, FireWire and 7.1-channel audio.
