|OK, I don't know why you are configuring anything so an explanation would be helpful. |
To address a couple of things you mentioned.
First, if you have two IDE drives on the same cable you MUST either use CS (cable select) on BOTH, of use Master on one and Slave on the other. When using Master/slave settings it doesn't matter which connector on the cable you use. That can be advantageous when routing cables. When using CS the drive connected to the end of the cable is always the Master.
Next, the boot order. There is no advantage to placing floppy & CD after the hard drive, IMO. I configure this way.
Floppy, CD, hard drive. If you wish you can make the first boot device disabled. That way, if you do need to boot to a floppy drive you can just make ONE change in the boot order. Some folks are in such a hurry they can't wait the extra 8 seconds The POST takes to check for disks in those first boot devices.
However, if for some reason you can't enter the BIOS to change the boot order and need to boot to floppy or CD you will be glad you set it that way.
Some folks don't have any faith in SMART. I feel it has some value and I enable it.
Is the computer in question part of a business network? If not where would you ever boot to a network device? The message you get is an attempt to boot to a netwrk device.
This is most likely caused by improper jumper settings or cabling. The IDE controller you are connecting the cable to must be enabled in the BIOS. That may or may not be the current status.
One other thing to mention. If you have not partitioned, formatted and installed an OS to it, you can't boot to a hard drive.
