Yikes! Last night I was testing a REALbasic program I've been developing on my
PowerBase 180 (tower). This computer has a 2 Gb IDE internal HD, internal SCSI
CD-ROM drive, and 72 Mb RAM. Because the program had locked the machine up
pretty tightly (an endless loop in the program being the most likely culprit), I
did the usual 3 finger salute to restart. This has worked okay several hundred
times before, but last night the PB180 would not boot back up. I get the gray
screen and see the smiling Mac icon in the middle, I can hear the hard disk
making its usual set of clickety chunkety noises, but then eventually (after
about a minute) all falls silent and I've still got nothin' but Smiley Mac
sitting there grinning at me.

I've already tried the following:

1. Boot from Mac OS 9 CD-ROM (nothing happens).
2. Reset PRAM (same result only now I see a bigger Smiley Mac).
3. Retry boot from HD (several times).
4. Retry boot from Mac OS 9 CD-ROM (several times).
5. Try (and retry) boot from original PowerComputing CD-ROM (OS 7.6?).
6. Unplug power, let it rest a few minutes, unplug all external peripherals
(except monitor), check / reseat all internal connections (including RAM), and
then retry the various boot procedures described above. I did this several times
too.

All I ever see is Smiley Mac except when I do the 4 finger salute to boot from
CD. Then it shows the floppy disk icon and the floppy disk icon with the "?" on
it for a few seconds as it tries to boot from the CD. Finally I just see ol'
Smiley Mac again. It never gets past that point.

On the positive side, it does respond the the mouse before I see Smiley Mac, and
it does respond to the keyboard combinations for restart, CD-ROM boot, and PRAM
reset, so I know the machine is not totally dead. It's just refusing to boot
from either HD or CD.

Any suggestions for getting it to boot again? Thanks in advance!
