If "special segment" flag is set, 0x214 bytes are read from CfgS:GetConfigInfoBlk8 block 0x70000, and then copied to the special segment given. If the reading fails, zeroes are written in its place.
Each segment record:
| Offset | Size | Description |
|---|---|---|
| 0 | 4 | Offset data |
| 4 | 4 | Load addr in 16-bit words (must be < 0x20000 for type 0, < 0x10000 for type 1,2) |
| 8 | 4 | Size in bytes |
| 15 | 1 | Mem type (0=1=0x1FF00000+,2=0x1FF40000+) |
| 16 | 32 | SHA256 hash of segment |
