Ultibo FileSystem interface unit

Numbering of Devices, Partitions, Volumes, Drives etc

Example:

Machine with 2 Floppy drives, 2 Fixed drives

Fixed Drive 1 has 2 Partitions (1 Primary and 1 Extended)

Fixed Drive 2 has 1 Partition (1 Primary)

\Floppy0 = Device 00h/Partition 0

\Floppy1 = Device 01h/Partition 0

\Harddisk0\Partition1 = Device 80h/Partition 1

\Harddisk0\Extended1 = Device 80h/Extended 1

\Harddisk0\Partition2 = Device 80h/Partition 2

\Harddisk1\Partition1 = Device 81h/Partition 1

\Volume1 = \Floppy0

\Volume2 = \Floppy1

\Volume3 = \Harddisk0\Partition1

\Volume4 = \Harddisk1\Partition1

\Volume5 = \Harddisk0\Partition2

A: = \Volume1

B: = \Volume2

C: = \Volume3 (Alternate Name = \HarddiskVolume1)

D: = \Volume4 (Alternate Name = \HarddiskVolume2)

E: = \Volume5 (Alternate Name = \HarddiskVolume3)
