Help, I think I wrecked my PB (G4, 1.5Mhz, 1GB, Tiger 10.4.8)! It will only start up in safe boot, with limited extensions, and now it thinks it has no airport card anymore. I watched the Macworld keynote as QT film, but paused it when I had to answer a longish telephone call and also put the PB to sleep. When I returned to the PB an hour later and woke it up to resume watching the keynote, it kernel panicked. At first I thought oh well, knowing I have neatly backed up all my documents, but soon found I was extremely limited in safe boot mode. I tried disk repair etc, had a run with the original hardware test CD, nothing. Tried killing PRAM. Eventually tried reinstall of Tiger, but I git kernel panics every time the DVD starts. I must have somehow knocked out some system files , I guess. Unfortunately I do not have backups of those. Any ideas? ANY help appreciated.
