I'm having a problem migrating an existing system to a Hardware RAID1 configuration.

I have a Fedora Core 1 server set up with a single IDE drive and want to add another via a Promise TX2000 card, RAID1 for data security.

I've sucessfully mirrored the drives, I've got working drivers, a working (i think) initrd with the proper driver. I can't seems to find any HOWTO's that reference how to update an existing system to recognize the RAID device and boot from it with GRUB.

I'm doing this on a test system before I try it on the server, so i'm willing to try anything.

Thanks in advance.
