Hey everyone,
Some years back I was given a PB520 with System 7.5.3 running on the default 4MB of RAM. It was fiendishly slow.
Recently, I've been attempting to install System 7.1.1 with the appropriate 500 series enabler. The installer operates without a problem, and during the installation the system gives every impression of being perfectly functional.
After installation, and for every reboot thereafter, the boot will not proceed beyond the "Welcome to Macintosh" dialog, at which point startup comes to a halt and the dialog box begins to flicker. Booting with extensions disabled brings no improvement.
Something early on in the boot process is going awry, but I'm not sure what. This is, as far as I can tell, the appropriate installation media, which I prepared on a different 68k machine using disk copy and floppies. While the image files were downloaded, this was done in a closed "old Mac" environment with resource forks, etc. intact.
Disassembly has yielded no clues. Is the backup battery critical to boot? Aside from this, I'm at a loss as to why it can't fully boot.
