below describes what I'm dealing with: To set the boot device on the Syba ATA133I, reboot the system in which the card has been installed. During the boot cycle, the card will post and show the following message: Sil 0680 ATA/133 Controller Bios Version 3.2.10 Copyright © 1997-2003 Silicon Image, Inc. Press F3 to enter Configuration Utility Press F3 to enter the BIOS. The card will then display the devices attached to the card and will show the following lines: Press F1 to assign first (HDD) set Press F2 to remove first (HDD) set Press ESC to exit Press F1. The screen will then show: Enter the Set number selected Press ESC to exit Your Selection? Enter the set number of the drive that you want to become the boot drive. Press ESC to exit the utility. Your selected drive will now become your boot drive. In addition to these settings you will also need to adjust the motherboard’s BIOS to boot from the Syba SD-ATA133I IDE controller. Please refer to the motherboard’s documentation on how to choose a boot device in the BIOS. Note:>/b> The process of assigning a boot device would not need to be utilized for attaching non-bootable devices such as DVDs or CD-Burners. my DVD-ROM is connected to the IDE Controller Card.BIOS detects it but my computer doesn't.I went into BIOS>BOOT>BOOT DEVICE PRIORITY and disabled the DVD-ROM.then I went thru Configuration Utility and pressed F2 to remove it.no effect.
