I have a Sony Optiarc BluRay drive (Sata) attached to my DX58, and 2 USB 2.0 Optical Drives (Liteon CD and Pioneer DVD).
If the Optiarc is active (SATA signal line plugged in), the 2 USB drives DO NOT appear in the boot list in Bios Setup.
The Optiarc WILL NOT boot.... Light blinks during POST, Post messages are OK, but then it just Hangs.
Unplugging the Optiarc allows a boot from one of the USB drives.
Any possibilities -- Maybe the Sony drive is defective? Has anyone else experienced this?
