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 |
|---|---|---|---|
| D | Alert type: DeadEnd (bit 31 is set) or RecoveryAlert (bit 31 is not set) | 31 | 1 bit |
| I | ROM subsystem number | 30...24 | 7 bits |
| GG | General error: roughly indicates what the error was | 23...16 | 1 Byte |
| SSSS | Specific error: indicates more detail | 15...0 | 1 Word |
