Event log complains about ATAPI settings

I've been getting the following messages on my Micron for more than a year:

A conflict has been detected between two drivers which claimed two overlapping Io port regions. Driver atapi, with device <\Device\ScsiPort2.Translated>, claimed an IO port range with starting address in data address 0x28 and 0x2c, and length in data address 0x30.

Now they have been joined by a third:

The Messenger service hung on starting.

The hard disk and Zip work just fine, but my floppy is unreliable... and I can't find any documentation on the "Messenger" service.

Do I have a problem? If so, how can I fix it?

Thanks,
Mick
