Hi, As a follow-up on my original e-mail (please see below for original message), I noticed an e-mail in this list from Gautam Goel that described a similar situation with Radeon video cards. I followed the instructions from Gerald Hanuer and have a functional solution to my problem.
In case anyone else is dealing with Radeon graphic cards or installing OpenBSD onto a similar iMac, I’ve listed the steps I took below. My first attempt was to use “boot -c” and “disable radeondrm” and “quit” from the kennel config as per Gautam’s e-mail. In my case, this didn’t work - when I would get to the kernel config prompt, no text I entered would display and typing the commands in blindly did not work. For whatever reason, text input via keyboard did not work. As per Gerald’s e-mail, I manually downloaded firmware from OpenBSD.org for Radeon hardware (http://firmware.openbsd.org/firmware/5.7/radeondrm-firmware-20131002p0.tgz). I then ssh’ed into the iMac, mounted a USB thumb drive that I had copied the driver to and then ran “sudo fw_update -p /path/to/copied/firmware”. I ran “sudo fw_update -i” to check if anything else was required and discovered that I needed another piece of firmware (http://firmware.openbsd.org/firmware/5.7/uvideo-firmware-1.2p1.tgz). I followed the same procedure again and rebooted the iMac via SSH. Thank you Gautam and Gerald, for your e-mail’s to the list!
