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 file name 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.
