I have an old LGA 775 mobo, dual core, with AGP 8x, DDRII, etc.

Forgive my ignorance, but I have two IDE (ATA 133) ports. Whenever I try to hook up two optical drives to one of the two IDE ports, only one of the optical drives work. I can unhook the drive that worked and hook up the one that didn't work and suddenly the one that didn't work before works. I tried this with both of the mobo's IDE ports and can only get one device to work per port.

Is it possible my motherboard only accepts one device per IDE port?

You should be able to hook up 4 x IDE drives w/2 IDE ports. I would check your cable and/or the options on the back of your drives. If I remember this right, you have to have 1 drive as the Source and the other as Slave. I think you might also be able to use the CS (cable select) option too, but it's been a while since I dealt with this before.

Options in the picture below (you have to have the jumper (white colored in picture) inserted into the correct position):

Thank you. You nailed it! I just had to mess around with the jumpers. My first build had SATA connections, so this is my first experience with older formats that needed a master, slave configuration.
