So you are using MD Raid (Linux Raid). This is different than the "bios" raid that David mentioned. In your case you don't need to set anything in the bios for this to work properly.
You didn't mention what Raid level you are using, but from your drive info it looks like you are stetting up a Mirror on two partitions. This
Yes, RAID 1.
I put all partitions of this install on MD raid, similar to yours, but I had a problem with /boot not working if it was on an extended partition. The only way I could get it to work was to make a primary partition for boot (two actually, 1 on each drive, the same size - make the partition first, format it with MD raid later). Then I made an extended partition to for all the other partitions. Then I set up each MD raid, boot on the primary partition, all the rest including swap on the separate extended partitions and all has been working well.
All partitions were made "primary".
I agree Jim that sw raid doesn't need anything to be set in the bios, but if the fake raid *has* been configured, then it will need to be set as bootable on some boards or the boards will refuse to boot from those drives at all. My Gigabyte 7N400 is a perfect example of that. In the bios, you have a Promise (or nVidia) Raid utility that selects the drives included in the array, provides a hardware rebuild function, and determines whether the raid array is bootable or not.
Hmm. I poked at the bios, saw that it had "Raid Mode" for the SATA drives, but left it in "SATA Mode" when I did the install, so I think that should not be interfering with my install. I could reboot and check in the bios to see that such is still the case. I wonder if in some odd way the bios thinks that the "boot sequence" does not include the SATA drives... have to check that.
This may not apply to Michael's case, but if his board offered any raid function, even the windows fake raid, and he set the array up in the bios, the in some cases he *will* have to set that as bootable before the bios will pass control to the array to boot. 2 out of 3 of the last 3 raid 1 systems I set up were like that.
The 'fdisk -l' I posted shows that both /dev/sda1 and /dev/sdb1 (where I put /boot) are marked as Boot. Thanks to all who have chipped in here.
