A week ago, I got two more hard drives for my home server. The plan is to make a RAID 5 array with 1.5 TB of total space. The problem is that the [Jetway J7F4](http://www.jetwaycomputer.com/VIA3.html) board I have only has two SATA ports. Luckily, I had a 2-port SATA PCI card and got the PCI riser card for my case. Putting a PCI card in the [Chenbro case](http://www.chenbro.com/corporatesite/products_detail.php?serno=100) requires taking off the bracket and delicate routing of the cables around the card. Unfortunately, when I put the card in, the system wouldn’t turn on. Then, when I removed the card, the system also wouldn’t turn on. I assumed that I had touched the motherboard and damaged it.
I bought a new motherboard, the [Intel D945GCLF2](http://www.intel.com/Products/Desktop/Motherboards/D945GCLF2/D945GCLF2-overview.htm) board. It has the dual-core Atom 330 processor and Gigabit Ethernet but is still as cheap as original Little Falls Atom board. I got it installed in the case and it booted. The Realtek RTL8111/8168B Ethernet chip wouldn’t work with Linux. I had to get the new [r8168 driver](http://wiki.centos.org/AdditionalResources/HardwareList/RealTekRTL8111b). It is still flaky and will only do 100Mb/s.
When I put in the SATA card, it wouldn’t start. Then I noticed that the PCI card was backwards. The card was keyed for both 5V and 3.3V slots and would fit backwards in the 5V slot. Which is easy to do when the bracket is removed from the card. I am pretty sure that this destroyed the old motherboard and probably the card since it did not work when put in the right way. I am going to have to get a new SATA card.
