"I hooked up my gigabyte DVD-RW as master and my IDE Western Digital 80g 7200rpm as slave, to the only IDE slot"
Ok, try something more common.
Put both drives on CS, then use your 80 conductor cable with the hard disk on the Master connector and the DVD drive on the Slave connection. Set the BIOS to boot from CD/DVD.
I can see deep trouble if you stray from the (Microsoft) path.
I recently replaced my motherboard with a New GA-965P-DQ6 motherboard,and a Core 2 Extreme QX6700. it has 1 IDE, 1 FDD controller and 6 SATA slots. i am using a 650 PSU from Antec and a Big Typhoon cooler. From preparation to reboot into Windows XP i was told to reboot from the Windows XP Home edition install CD. I hooked up my gigabyte DVD-RW as master and my IDE Western Digital 80g 7200rpm as slave, to the only IDE slot - also changed the pin setting behind the drives. then when i turned the PC on, i went into BIOS setup and set it to boot from CDROM first (there is only 1 selection for optical drive). However, for some reason, the startup just couldnt recognize the DVD-RW and couldnt boot from it. Can someone please help as i am stressed and befuddled (tried switching master and slave but it didnt work)
