RAID Controller

I’m considering a RAID controller to increase performance, but I would like to know if I can actually boot off the drives on the RAID controller. For example if I was using my RAID controller at Level 0 or Level 5 (data stripping), with two 20Gb HDD’s, and wanted to boot the OS of those drives would my BIOS display this a one 40 Gb drive or would it display it as two 20 Gb drives. And would it display it as a master & slave or two masters.

Yes, RAID HDD's are bootable. Your BIOS does not register the drives in the IDE detection durning POST. The RAID BIOS is what picks the drives up.

If you strip or mirror essentially one drive, it acts like one drive. Stripping shares the data between drives, and mirroring just makes a duplcate copy of the first drive.
