My IDE cable is fully occupied for I have a CDRW, CDROM and 2 HD.. i own an Intel 850GB MOBO, i was wondering whether any expert out there mind telling me how many IDE slot is there available in this kind of MOBO. I plan to get a DVD later in the future...
Generally unless you get a specific RAID supported motherboard, you will be able to connect 4 IDE devices. Normally this is two controllers (IRQ14&15-IDE0 & IDE1) each is capable of supporting two drives, 1 master 1 slave, connected together on 1 cable.
So you have your CD/DVD drive and CDRW on IDE0, CD/DVD master, CDRW slave. Then on IDE1 upto 2x harddisks, again 1 master , 1 slave.
Check your manual if your board supports RAID, thats a whole new ball-game.
