Triple Boot on Two Drives?

[rumplestiltskin]

I'm carefully reading the triple boot wiki, but I'm not sure how the situation changes if I have two HDs installed (Mac Pro). The second drive is new, unformatted.
I want to be able to boot OSX from either drive (in case one has a problem). The first drive is OSX only, the second should be OSX (minimal)/Winders XP SP2/Debian etch.
Will rEFIt see the partitions on the second drive if installed on the first? (Will it see the first drive if installed on the second?)

Any other issues I should be aware of?

Thanks..

Now that I've thought about it for a bit, I think I might be wise to put the Linux partition on the first drive, and the Winders partition on the second. Or vise versa. Then both drives would have two bootable partitions only, and Linux could have a swap partition. Prolly easier to do.

I would still want a single boot menu at startup, to boot from either drive. Anybody try Bombich's BootPicker? I guess it's just a batch file that blesses the selected partition, for one time only.

I've never tried that particular tool; I'm using rEFIt for my triple-boot system. (MacOS/Vista/XP)

(I don't have a secondary harddrive in my iMac either, but nobody else seems to be responding to your query... so I thought I'd chime in.) I would imagine that the principles of booting off of one harddrive with multiple partitions, vs booting off of two harddrives with multiple partitions wouldn't be much different. After all, we're talking about a Macintosh here, and historically, you could boot a Mac off of just about any accessible drive. (I once experimented with MKLinux on my old PPC Mac, by booting it off of a 1GB external SCSI based Jaz drive.) This has only changed fairly recently, with the advent of external USB and Firewire drives, in that some Macs can only boot off of one or the other. But I'm guessing that you're not talking about an external drive... so I'd be surprised if you had any problem seeing your drives from a bootloader.
