Format of the alert error number

The 32 bit long error number consists of 4 segments. Amiga displays the number in hexadecimal and in a general format it looks like this:

0xDIGGSSSS

The letters have the following meaning:

Letters in Code Description Bits Length (bits)
D Alert type: DeadEnd (bit 31 is set) or RecoveryAlert (bit 31 is not set) 31 1
I ROM subsystem number 30...24 7
GG General error: roughly indicates what the error was 23...16 8
SSSS Specific error: indicates more detail 15...0 16
