What are CD-ROM/WR and DVD-ROM+/-WR?
CD-ROM (compact disk read only memory) is removable media drive that hold 750+ megabyte of data.
CD-RW (compact disk re-readable re-writable) is extension of CD-ROM that allows data to be erased and write again.
DVD (digital versatile disk) store close to 10GB for single layer and 17GB for dual-layer disk.
DVD can store movies with high graphic and sound quality and data.
DVD+/-RW (DVD re-readable re-writable) is extension of DVD-ROM that allows data to be erased and write again.
What you should know
CD-RW is identify by front numbers like 52x32x52 which refers to its reading and writing speed.
Higher numbers are better to read and write faster. CD-ROM will only have one number at the front, for example 52x.
Similar to installing hard drive,
the trickiest part of installing your compact disk is setting up
the jumpers. Most PC's use IDE connection and accommodate
two drives per cable. Connecting two drives (Hard Drive/CD-WR)
to single IDE cable requires you to set jumpers; set first drive
(hard drive) master and second drive (CD-RW/DVD+/-RW) as slave.
If you connecting the IDE data cable to single drive, set the drive jumper to master or select.
You may have 2 IDE data cables connecting to the motherboard and each cable could connect to one or two drives.
Compact disks have audio cable that connects to the soundboard or motherboard.
Installing Compact Disk (CD-ROM/CD-RW, DVD/DVD+/-RW)
 Installing CD and DVD are same. They both have same connection pins and use the same method to connect.
1. Set the jumpers to master or select if unshared data cable is used.
2. Connect the IDE data cable to the mother board drive controller.
3. Connect the other end of the data cable to the compact disk drive
4. Connect the 4-pin connector from the power supply to the hard drive.
5. Connect your audio cable to the compact drive.
6. Turn on the computer and test if the compact disk drive works.
Your compact disk drive does not need any software or bios settings to work.
It should automatically work once you install it properly.
You can set the boot sequence in bios only if you need to.
