I have a CHAINTECH 7NJL6 motherboard. It worked fine about 4 months ago....haven't used util today,previously worked fine. Hard drive shows up as slave rather than master and system won't boot. Checked pin on hardrive it was set for auto detect, bios set to auto. Moved pin to master and it made no difference. Moved cable from channel 1 to channel 2 and hard drive detected still as a slave and auto detects drive type and settings. Have replaced drive cable and no differences....any thoughts of how to make it read as a master.
