Diskette 0 is the floppy drive. It is either not connected or bad. The automatic IDE configuration is a good thing unless it repeast. What it is trying to do is see what devices are connected to the IDE channels and configure them.

Normal items on the IDE channels...Harddrives, CD,DVD,Floppy drives.

Does the system post, ie gets past the big Dell splash screen?

Can you access the bios?

First thing I would suggest is to replace the battery. That system is fairly old and if you have not already done so I would highly recommend it. It uses a standard 3v CR2032 coin cell battery.

A weak battery can cause a lot of these type issues.

Assuming that you have no diskette drive, you should be able to solve the "seek error" by going to setup (F2 on startup), navigating to the entry for diskette drive, and setting it to "Off" or "Not Present", whichever option is available.  If the computer has a disk drive, you can try re-seating the power and data cable to see if the error goes away.  If not, the drive has failed.

The reconfiguration of the IDE channel can occur if you have started the computer without a disk drive present, or if you have uninstalled the IDE channel using the device manager.  This is normal and doesn't represent a malfunction.
