Can a raid board be used like a "regular" board i.e. 2 hard drives hooked
up as master and slave?<
Yes. Most have a "RAID" and "Base" mode. Base would be "regular"
What is CNR?
Cut and paste: CNR - CNR or Communication and Network Riser is a new type of
slot that supports audio, modem, USB and Local Area Network cards. This slot
is highly recommended for any user building a large amount of computers as
the cards are generally cheaper then the standard PCI or ISA cards.
