Mirroring with Windows 2000 server

Hi
I just completed what I think is Windows 2000 servers mirroring and now I have to drives that say c: volume

Disk 0
Disk 1

Afterwards I get this message from:
DISK MANAGEMENT

“You have mirrored your boot volume. To be able to boot fromthe mirrored disk, add the appropriate entry to the boot.ini file.”

How do I or what do I type in the Boot.ini for the appropriate entry and do I this now before I need to use the mirroring? How do I test the mirroring out to see if it will actually work for us when the primary c: volume crashes.

Is there a Q file with this information.

Thank You.
