Hi,
I'm in the process of repairing a battery bombed SE/30 and have managed to repair enough of the PCB traces and vias to get it booting up partially. I'm using a SCSI2SD device with a bootable 7.5.5 system installed and it gives me the startup chime, happy Mac, "Welcome to Macintosh" and then the progress bar screen appears and the progress bar moves a couple of times in quick succession but sticks at around 15% complete where it stops. At this point the mouse is still responsive so it hasn't hung up completely but it never progresses further.
I have tried booting from 6.0.8 on my SCSI2SD as well and it doesn't display a progress bar but instead it stops at what looks like an empty desktop with empty menu bar. Again mouse is responsive but nothing else happens.
I tried booting by floppy drive after cleaning the drive and finding some known-good 7.5.3 install disks but it seems to stop booting after a minute or so of reading from the drive.
Lastly, I have tried removing half my RAM SIMMS so that only bank A is in use and tried swapping the actual chips from bank B into bank A but that made no difference either.
Oh and I tried booting into safe mode and it confirmed extensions would not be loaded but that didn't help either.
Any ideas on how I can figure out which stage of the boot process is failing? Does the SE/30 support a verbose boot mode or can I monitor the boot process in some other way?
Many thanks,
Craig.
