I have a ASUS A8V Deluxe mobo, and two ODD (DVD writer and a DVD drive). I cannot boot from either IDE ODD drive on a regualr basis. It doesn't seem disk dependnent (orignal CDs and burned ones seem to work/fail with the same frequency). I have updated the mobo bios and the ODD firmwares to there latests versions and this did not fix the probelem. I have swapped cables, disconnected/reconnected the drives. I even tried a new drive and cable from a working computer. The bios (POST??) always detects the ODD drives, it just cannot boot from the drive. When I boot into Windows 2000 from the SATA HDD, the ODD drvies are always found, but they often do not recognize the CD/DVD and says "Insert Disk". Is this an IDE controller failure or something else? How do I test for IDE controller failure? Is there a work around besides replaceing the mobo?
