I just built a computer for a sibling who is without one. There's no operating system in it yet. I need to install that from the cd/dvd combo drive. A new computer doesn't get much more fresh than this. But wait! I can't because the BIOS cannot detect the IDE connections in the CMOS! Even in the Boot Order, the cd/dvd is not listed. Okay, inventory: There's an MSI K9N6GM AMD motherboard, lower end, about $50. A Thermaltake 450-watt power supply. An IDE Sony cd/dvd combo drive. There's a SATA Western Digital hard drive. Not a high-end computer. It's not supposed to be, but it's better than an e-Machine. Once I have this resolved, I'll put Ubuntu on it. Now for testing...I tried switching IDE cables (I always be sure that they're on correctly, along with power connectors), and that didn't work. I tried a different cd/dvd combo drive. That didn't work, either. Now I'm thinking that just leaves the IDE connector on the motherboard...maybe it's faulty. But before I jump to conclusions, I thought I'd check over here to see if there's anything I might have missed.
