for the TriggerLevel property are as follows:
1- Other
2- Unknown

Shareable Indicates if the IRQ can be shared. A value
of TRUE indicates that the IRQ can be
shared.
Boolean
Hardware Indicates if the interrupt is hardware- or
software-based. (A value of TRUE indicates
that the interrupt is hardware based.) On a
personal computer, a hardware IRQ is a
physical wire to a programmable interrupt
controller (PIC) chip set through which the
microprocessor can be notified of time
critical events. Some IRQ lines are reserved
for standard devices such as the keyboard,
diskette drive, and the system clock. A
software interrupt is a programmatic
mechanism to allow an application to get
the attention of the processor.
