I submitted this to tech support today - have searched a number of forums on this subject without a conclusive answer, only the recognition that it is a problem. Thought I would run it up the flagpole here, and see if anyone salutes: I have written about this on various forums. My motherboard is an ASUS P5B Deluxe WiFi with something called a "JMicron Controller." This newer motherboard has a great deal of trouble with disk drive detection in Linux and Acronis. The most bothersome problem is that, once installed, Acronis OSS, when started, does not detect the CD drives, making it impossible to install new operating systems on the system. Some people in the forums have suggested that I request a program or ISO file from you that will support my system. Apparently a newer kernel is needed that supports my system, with two SATA hard drives and two IDE CD/DVD drives. The only way I can use Acronis DD or True Image recovery disks is to boot them into "safe" mode which is not very useful.
