Slave/Master drive

Sooo yeah, how which drive is supposed to be set to what? and what does it mean exactly for a drive to be set one of the ways?

basic explanation :
- for an ide channel to support 2 drives, one has to be master, one has to be slave.
- the master drive is what the pc talks to, and when the pc wants to talk to the slave drive it must do so through the master drive.
- booting is generally possible only on the master on older bioses, and to boot of slaves you must usually select the drive from a boot menu on newer bioses
- placing 2 drives on an ide channel results in a performance hit as both drives must share the channel's bandwidth.
- cs means the drives themselves negotiate which is slave and master, but you need a special cs ide cable.
- MORAL OF THE STORY: boot drive is master, other drive is slave, but put them on separate interfaces if you can.
