I'm trying to install a 2nd hd but bios is not recognizing it at all and when i try to restart the comp it tries to boot from this hdd that bios wont even recognize. I know this subject has been exhausted in this forum and ive read 30 posts about this but they all have the same answers and these arent working for me no matter what i try. I keep seeing people say to jump the pins on the back of the HDD that say mastet, slave, cable select but i dont know or where to plug these pins in. I have nothing plugged into those on my master hdd that is working now. Can someone walk me through this. i would like to trying setting the slave pins to see if bios will recognize it.
