[dba-Tech] Re: RAID definitions etc

...wait a minute ...mirrored drives ...new motherboard ...install only one
HD ...insert the motherboard drivers CD and boot to bios ...change the bios
to boot from the CD ...reboot ...when the CD prompt is raised installed the
motherboard drivers ...remove the motherboard drivers CD and insert the
Windows XP CD ...reboot ...when the Win install options are raised, select
the (R) option to "repair" the XP install on the HD using the current mb
drivers ...reboot and you should have a completely functional system ...now
you can install the 2nd HD, format it, and rebuild the RAID mirror using the
mb raid functions.
