Hello Everyone,am a newbie when it comes to installing HDD and DVD, CD and Burners. I have a PC which my Engineer told me that I can only use two IDE ports on the motherboard. I feel it is a waste of SATA cable, but I obliged because I can't do otherwise. However, I just reinstalled and  changed the OS of Windows XP1 to Windows XP 2 because of viruses and I just decided to up the OS to allow me have real player 11 installed, it or the later help to rip songs and stuff from youtube.com and other sites. Now I discover the system comes up and works sluggishly but I plan to up the RAM from 256MB to 256MB + 512MB, but now my problem is how to reset my CMOS settings. I only want to use my primary IDE slot to power and connect the HDD and DVD ROM on one channel.So I made my HDD the primary MASTER and DVD ROM the Primary SLAVE by putting the jumpers at the first position and second respectively. When I ran the PC, it told me there was an incompatibility at primary Master ATAPI,when I run at AUTO, it works. And from BIOS, HDD is my first port of call. I would love to have the manual settings. Now the middle of the cable is on the HDD and the other end is on the DVD ROM and I really want it to stay that way. But I guess the middle means slave, so does the jumper override the cable positioning? So that I can have PRIMARY MASTER-HDD, PRIMARY SLAVE-DVD, SEC MASTER-Not Installed, SEC Slave-Not Installed.I don't think I will notice or complain of any sluggishness with over 600MB RAM.
