Have a great day,
Thanks. Your reply is appreciated. What finally worked was i located an installation disk that did work. The machine acted like it wasn't recognizing ANY CDs until we found one that did work (a 10.4.7 disk). 10.4.2, 10.4.4, and 10.2.1 disks were not recognized whatsoever using Control-C on startup.. I tried every key combination on startup (about 10) without success also. Control-S on startup DID call up the code screen that allowed me to try the hack that worked on several other machines in the past, but not this one. I am learning a lot about the Mac 10 OS as the building has about an even split of Mac 10.4.x and Windows 7 workstations. Most of my past experience was with Windows buildings.
