What is the proper order for my SCSI devices?

I have:

32x Plex reader
40x Plex reader
124T Plex burner

I think I now have them mismashed as Dev. 3,4,5. I believe there is an optimum pecking order. Nearest the card? Is the card 9 or 0. Geez...I knew this stuff once. Suggestions on device order/id?


-------
Also, unrelated, I have my two IDE hard drives (each on a separate ribbon) on my Promise/66, and boot to C: on my Asus P3B-F. I have my mobo headers disabled. I wanna add a couple hard drives, and may add another Promise card (I believe this would make the first Promise card the boot card?), or may just add to the mobo headers.

I'm thinking that if I add drives to the mobo headers, then, to boot from the C: partition on the Promise card, I will have to set the BIOS to boot to SCSI? I'm guessing the reason I can have it set to boot to C: now is because I have no mobo headers enabled? Can someone confirm I'm thinking correctly?

------
Oh, also, I'm gonna add my Iomega/Plex 12x10x32x burner to the mix. If I also add two more hard drives, I'm gonna have to put a couple devices on one ribbon, rather than giving every ide device it's own, or keep them separate by adding a second Promise card and enabling one of the mobo ports. If you suggest not using the 5th drive header, which two devices would you suggest putting on the same ribbon? The two hard drives I'm adding?

Suggestions? Anyone else played with a system this cobbled together?

Thanks,

Usually the id of the SCSI card is 7. ID order doesn't really matter all that much, 3, 4, and 5 should be fine for cd drives, I wouldn't even tinker with it. I've heard ID 6 has the highest priority on down to 0, but it doesn't really make a difference.

About booting from a hard drive hooked up to a promise card, I think you're right all you have to do is tell the motherboard bios you're booting from SCSI. Basically it just tells it that you're not booting from the onboard ide.
