Greg,
I must say that your subject line (tragic though it is) is the wryest one I
can recall on this list. It conveys the grave situation without the hysteria
so common to subject lines ("MY GOD!!! SOMEBODY HELP ME!!! PLEASE!!!!!").
I'm not certain what you need to do to resurrect your machine, though you
may be interested to see what Power Computing's service manual says
regarding the Rule of CUDA. To quote:
The CUDA Reset button is a small red button located on the Main Logic Board.
Depressing this button resets the CUDA Microcontroller Chip.
This chip is responsible for the following functions:
* Turns system power on and off
* Manages system resets from various commands
* Maintains parameter RAM
* Manages the Apple Desktop Bus (ADB)
* Manages the real-time clock
* Lets an external signal from either Apple GeoPort serial port control
system power
It is rarely necessary to reset CUDA, but many problems that appear to be
hardware related can be fixed by doing so. Resetting CUDA will not harm the
machine in any way. Some of the most common reasons to reset CUDA are:
* After adding RAM, the machine will not boot, RAM does not show up in the
memory control panel, etc.
* Machine will not power up
* Machine powers up, but does not chime or boot
* A serial port remains inaccessible even after booting without extensions,
resetting parameter RAM, etc.
* Machine will power down for no apparent reason
* After adding any hardware to the inside of the machine
Resetting CUDA
1. Shut down the computer and disconnect all external devices, but leave the
power cable plugged in to ground the computer.
2. Remove the cover (refer to Side Panel Removal/Installation on page 6).
3. Touch the metal chassis of the machine. This will dissipate static
electricity into ground.
4. Locate the CUDA Reset button (see MLB Diagram on page 5).
5. Press the CUDA Reset button for a few seconds.
6. Reboot, and verify resolution of the problem you wanted to solve.
NOTE: Resetting the CUDA will cause some system settings to default to
factory settings.
