The MB is H8DGU-F, AMD SP5100 chipset. Two hard drives are connected to onboard SATA port 0 and 1 for RAID1 configuration. One SATA DVD-ROM is connected to SATA port 2.
The problem now is when SATA RAID option is enabled, DVD-ROM can't be detected in BIOS for booting purpose. Please advise how can I use the DVD-ROM for OS installation when using RAID mode.
Please connect the SATA DVD-ROM on last SATA port 4 or 5 when using RAID mode.
