what is device 0, device 1 in the Device manager's primary and secondary IDE channels?

Hi,
Can anyone explain me:
(1) In the device manager what is the IDE ATA/ATAPI controllers ?
(2) What are the primary and secondary IDE channels?
(3) What are device 0, device 1 etc. in each of the channels?
(4) In the Advanced tab of the Primary IDE Channel properties, can I put Device 1 to 'Type: None', instead of the current setting:'Type: Auto Detection'?
(5) Can I do the same in the secondary channel?

Note: I have 1 hard drive, 1 DVD +RW drive, 3 USB slots.
I want to do this to speed up booting, as a friend of mine suggested. Is there any ill effect to this?
Thanks a lot.

Hi sbaruah,

Most computers have two IDE channels (IDE0 andIDE1), which are presented on the motherboard as two large (40 pin) sockets

( NOTE: Some PC’s have built in RAID capability and may have more than two IDE sockets (consult the motherboard handbook)

Each of these sockets can support two IDE devices, device 0 and device 1 (giving you a total of four IDE devices)

Hi sbaruah,
    1) IDE are the channels where you connect HardDisk, CD drives, etc.
    2) There are two IDEs on the motherboard.. one is primary and the other is secondary.
    3) Device 0 is Master, device 1 is Slave
    4) If you do so, the device connected to that channel(CD ROM/ CD RW/ DVD / another HDD etc). wont work
    5) Same thing
   

Bye
