Much help is appreaciated fellows, I recently tried to upgrade my firmware for my Samsung SD-612B, I went to Samsung's website and found the driver. All went well untill after it asked me to restart, which after i had done so, my DVD-ROM drive WAS NO LONGER DETECTED by my computer. Not under devices manager, not to be detected in BIOS. I've tried all the other drivers, tried the registry settings, i've tried all the jumper combos, all the BIOS settings, I HAVE NO CLUE WHAT TO DO!!! SOMEONE PLZ help me out!!! THANKS
