The Order field is used to force a sequence of events; Order=0 is first, and Order=99 is last. Two items which have the same order are installed in the same pass, but not in a predictable sequence.

The Delay field is used to add a delay after the item is loaded, before the next is loaded. The delay is given in seconds, and defaults to 0 if not specified. If the install fails (or the file to be installed is not found), the delay does not occur.

The PCMCIA field is used to indicate that the file (usually a CAB file) being loaded is a radio driver, and the PCMCIA slots must be started after this file is loaded. By default, the PCMCIA slots are off on power up, to prevent the “Unidentified PCMCIA Slot” dialog from appearing. After the drivers are loaded, the slot can be turned on. The value in the PCMCIA field is a DWORD, representing the number of seconds to wait after installing the CAB file, but before activating the slot (a latency to allow the thread loading the driver to finish installation). The default value of 0 means the slot is not powered on. The default values for the default radio drivers (listed below) is 1, meaning one second elapses between the CAB file loading and the slot powering up.

Note that the auto-launch process can also launch batch files (*.BAT), executable files (*.EXE), registry setting files (*.REG), or sound files (*.WAV). The mechanism is the same as listed above, but the appropriate OS application is called, depending on file type.
