A guide to Guru Meditation Error Codes

Format of Guru Meditation messages:

 

Subsystem ID

General Error

Specific Error

Address of task

00

00

0000

00000000

 

If the first digit of the subsystem ID is greater than 3, there is no way to recover from the error. In these cases, subtract 8 from the first digit to get the subsystem ID number.

CPU traps or exceptions are defined by the CPU and not the AmigaOS. There are 256 vectors for CPU exceptions: with the lower 64 being hardware defined and the upper 192 being user definable. Specific examples of some that would show up in a Guru meditation error are as follows:

00000002

Bus Error

Address error

00000004

Illegal instruction

00000005
