OK, embarking on an attempt to upgrade a 27" iMac 11,1 with a WX4130...
Have built and tested the grml USB stick, and had verified that it has been able to boot this machine and deliver an IP address. As preparation for flashing the new card, etc., I'd collected ROMs I was gonna try flashing, I've been able to SSH in to the machine, etc., both with and without the video card installed. So far so good!
However, unluckily, my already flaky (original) video card gave up the ghost. It had been limping along in Safe Mode; some screen stripes - obvious faults - but it had been at least working. A couple of days ago, it heated up tremendously and, now, no output to screen at all. OK, presuming dead video card...
Now, though the machine seems to boot OK - I get startup chime, etc. - grml seems to not completely boot. IE, I never see the machine on the net (I use nmap) and, obviously, cannot SSH in to it. Obviously, I have no way to see the progress of boot, so cannot diagnose the problem. (Is there any other way to see the output on boot?)
Is there a fuse on motherboard, or some other component one of you can point to, which might have gotten fried? Wouldn't it be great if it had just burned one fuse or capacitor or...?
