I just installed a FreHD with the autoboot ROM into my Model III and I'm not getting anywhere. I used someone else's known good SD card image and I can't seem to get it to boot.
To troubleshoot, so far I have replaced the ribbon cables from the FDC and the RS232 boards. I cleaned the drive connector on the bottom of the motherboard. I reseated the autoboot ROM in U106. I used a new cable from the FreHD to the motherboard. The stripe is towards the outside of the case. The FreHD.rom file is in the root of the SD Card.
On startup the FreHD LED flashes green one time but I get nothing on the monitor. Holding Break and booting the machine gives me nothing as well.
Does anyone have any thoughts as to what I may be doing wrong?
