I replaced the cd-rom in an iMac DV, and now the computer will only boot from the CD if the HDD and CD are both connected. When I disconnect the CD, it will boot from the internal HDD just fine.
I tried different jumper settings and whatnot, but nothing seems to work.
Do you think the little power board on the CD-rom might be the culprite? I have no clue at this point.
Any ideas of other things I should try? Or is this iMac going to be forced to use an external HDD forever?
