Guru messages (software crashes) occur frequently enough in the Amiga system to make a table of their values important for everyday use.
A Guru message takes the following form:
########.########
^ ^
Error Memory location of error
The memory location is not very important to most users, because it can change from program to program (programmers and developers may want to take note of it, however)
Memory Map:
$FFFFFF Kickstart ROM (256K) - Amiga 500 and 2000
$FC0000 Address copy of Kickstart ROM (256K)
$F80000
$F00000 Expansion slots
$E80000
$E00000 Custom chip register
$DF0000 Battery-backed realtime clock - Amiga 500 and 2000
$DC0000
$C80000 CPU RAM (512K) - Amiga 50 and 2000
$C00000 CIA B and...
$B00000 CIA A
$A00000 FastRAM (up to 8Mb)
$200000 Address copy of chip RAM
$080000 Chip RAM (512K)
$000000 ---END of memory---
The Gur error type has the following subdivisions:

Alert Type Error Exact Description
class
The confusing part is that these parts can overlap - the system class can be added to the Alert Type, depending on just why the system crashed. I will list the subdivisions of each type, and then some common errors.
When the Guru error begins with an 8 this means that the error is non-recoverable, ie that it will reset the computer. Otherwise the error can be trapped by any self-repecting programmer and turned into an error message.
To find the true error code when it begins with 8, just subtract the 8 and proceed as usual.
