On the process of trying to install a new hard drive on a iMAC G3, I get the following error message on boot up. It's the first thing that shows up on the desplay. At first I thought that it was not dedecting the new hard drive (Seagate 40Gb @ 7200 RPM), but when I installed the orginal drive (Western Digital 6Gb) back the, the same above error message continued to show. The orginal Western Digital 6Gb still has a working copy of OS8.6 on it. What is going on with this iMAC? How do I go about fixing it? Also how does one go about upgrading the firm were? Will I be needing a USB Floppy Drive for this. And finally, did there any way that I can check where or not a hard drive is MASTER or SLAVE with out having to manually open up the iMAC and physically looking at it.
