This morning we got a flashing world icon when we started up our Rev A G5 iMac, now I've see the flashing folder with a question mark, but never this. We reset the pram and all is well, but I was just wondering if anyone else has got this or if they know what was the cause?
If things were different, they wouldn't be the same.
That's what it looks like when it searches the network for a netboot server and doesn't find one. Sounds like it was having problems accessing the hard disk and it somehow defaulted to looking on the network for something bootable. If it went back to normal after resetting the PRAM (and slecting a startup disk as Gary suggests above) then you might be able to just chalk it up to PRAM weirdness. I'd make sure you have backups of this machine "just in case" though either way
