Update Mac OS 8.5.1 to OS 9.1

Posted on 2001-07-30
Last Modified: 2013-11-17
I have an older iMac with 64 MB RAM and about 3GB hard drive space left. It is running OS 8.5.1. I just bought a new airport and a new iMac running OS 9.1. Apple tech help tells me that I must be running OS 8.6 or later for them to be able to share files through the airport. I tried to do a clean install of a new system folder using the CD that came with my new iMac on the old one, but it told me that I needed to update the firmware first. It said to look in the CD Extras folder, but I couldn't find anything in there that mentioned firmware updating. How can I upgrade the system? Is this an insidious plot by Apple to drive me mad? Please help! And could you make it simple, please? I'm kind of technologically challenged.

I visited Version Tracker and did a search for firmware, but I couldn't find one that I thought applied to me. There was one for slot-loading iMacs, but mine is a sled, I don't have DVD-ROM, I don't have SCSI,and I didn't think that the modem update was the right thing. If I could find the right firmware update, this would be the perfect answer.
