Q1
How can I install OS when 4 SATA hard drives running in RAID mode on A880GZ?

Our motherboard will be able to support USB boot function.
By using USB converter to connect SATA DVD drive to USB port will be able to detect by motherboard BIOS and install Windows 7/8.
Then 4 SATA ports on board will be able to run under RAID configuration.
