kenrivers :
Are you asking if you can replace the DVD drive with an HDD using a HDD caddy and get it to boot from that drive instead?
Yuo thats it. It is the only way to get it wrking again. In fact, the main sata bay still functional, but not the power source. So for os install I'll provide power to the drive via another computer, and conect it to the main sata by an extension sata cable. After installing it I'll put it on the caddy, then try to boot from there the operacional system...I've looking for this aswer EVERYHERE on the web, but no one seen to have such a problem like mine...reflow on the main sata connector is not an option for me, since I'm far from the big cities...sorry 'bout my terrible english!
