XHDI functions
| Type | Meaning |
| BGM | GEMDOS partition > 16 MB |
| GEM | GEMDOS partition < 16 MB |
| RAW | Partition type RAW |
The following types can be supported optionally (for example with a configurable list of partition ID's in the driver).
| Type | Meaning |
| F32 | TOS-compatible FAT32 partition |
| LNX | Linux Ext2 partition, should be handled like `RAW' |
| MAC | MAC HFS partition, should be handled like `RAW' |
| MIX | Minix partition, should be handled like `RAW' |
| QWA | QDOS partition, should be handled like `RAW' |
| SWP | Swap partition, should be handled like `RAW' |
| UNX | ASV (Atari System V R4) partition, should be handled like `RAW' |

XHDI-1.10 compliant drivers shall support the third partition type RAW (in addition to GEM and BGM). For these partitions, the following should be true:
| (1) | The partition size is `arbitrary' (32-bit sector numbers).
|
| (2) | The partition can be accessed as a BIOS device; Getbpb
returns a NULL pointer (so that GEMDOS won't access it; however,
calling Getbpb resets the driver internal media change state).
|
| (3) | Rwabs (in physical or logical mode) and XHReadWrite may be used
to access the partition. The physical block size of the medium is used
(see XHInqTarget).
|
| (4) | XHInqDev2 (as compared to XHInqDev) returns size and type of
the partition.
|
These extensions have been made to make it easier to create drivers for new filesystems for MiNT or MagiC (like the Minix filesystem).
