Update: went ahead and cleared the uart codes and successfully booted to a white light no more errors on uart or beep....

Getting 3 beeps only when console is plugged into power, no lights. I was thinking a possible NOR issue but the uart codes are leading to something possibly more serious? EDM-010 disk edition. I didn't try clearing the error codes yet, wanted to backup the NOR first, CH341A programmer comes tomorrow.
