Here is the information you requested.
Monitors:
Samsung LCD 24 inch, port 2 of the card.
Mag Innovision CRT 19 inch, port 1 of the card.
I was installing the update ATI Radeon HD 2600 XT Firmware Update.
As I was reading the update notes, about 1/4 to 1/3 of the update completed the computer shutdown.
I restarted the computer. I heard the boing but no image ever appeared on my monitors and they stayed without signal.
I restarted the computer several times and always the same results. No signal to the monitors.
I can target firewire load the harddrives of my Mac Pro on my MacBook Pro. Therefore the drives and the system works.
I have tried zapping the PRAM, no change.
I have tried disk load by holding down the option key, no change.
Nothing on my monitors, they just aren't getting any signal from the card.
Any suggestions?
Thanks.
