Device Parameters for the IODevice %rom%
BlockSize integer (Read-only)
Free integer (Read-only) Indicates the amount (in pages) of free space available in ROM. Valid only if the
ROM is mounted (mounted is set to True). A value of 0 (zero) indicates that either the ROM
is not mounted or it is full.
HasNames boolean (Read-only) Indicates if ROM supports named files. Valid only if ROM is mounted (mounted
is set to True). If ROM is not mounted, this parameter has a value of False.
InitializeAction integer (Read-only) Always returns a value of 0 (zero), which indicates no action.
LogicalSize integer (Read-only)
Mounted boolean True System attempts to mount the ROM.
False System attempts to dismount the ROM.
When a device is mounted, it becomes known to the system and is readable, depending on
the nature of the device.
A device must contain a valid file system or it will not mount successfully. To verify if the
device is currently mounted, query this parameter immediately after setting it.
If the ROM device is dismounted, unpredictable results occur.
PhysicalSize integer (Read-only) Indicates the size of the ROM (in pages) that is mounted. A value of 0 (zero)
indicates that the device is not mounted. This parameter is only valid when ROM is
mounted.
Removable boolean (Read-only) Always False.
Searchable boolean (Read-only) Indicates if ROM participates in searches in file system operations that specify
a filename without specifying a device.
SearchOrder integer (Read-only) If the Searchable parameter is True, indicates the priority assigned to the ROM
when searching for a file and no device has been specified. A lower integer indicates a
higher priority. If the Searchable parameter is False, the value of this integer has no
meaning.
Type name (Read-only) Always returns the value of /FileSystem.
Writeable boolean (Read-only) Indicates if the files on the ROM can be opened for write access. Always False.
