Comments on: How to Designate a Start-Up Drive

on 11/22/2005 Make sure that the jumper on the CD-ROM is correctly set for the cable. For example, if the CD-ROM drive is at the end of an IDE cable, the jumper should be set to Master. A mismatch will cause the drive to not be recognized as a boot drive, even though it can be seen after booting from another device (e.g. from an HDD or floppy).

on 11/22/2005 When you start the PC; if you have message saying "Award BIOS. Version: (number)"
The boot sequence is usually found in the "Advanced" about halfway down.

IDE-0 is the C: drive - that is, this is the standard. this drive is also called the "Primary-Master" in the CMOS.
usually your CDROM drive is attached to the "Secondary Master" slot.
the Sequence I use is
Floppy Drive (for startup disks) --> CDROM (windows 98 - full not the upgrade can be loaded to install just from the CD) --> HDD-0 (C: drive)
