Introducing IRQInfo
===================
IRQInfo is a powerful interrupt identification tool. If you have
gone through the frustration of using a utility that incorrectly
identifies or "guesses" at the IRQs used by devices, then you can
appreciate how important accuracy is in a tool of this type.
IRQInfo focuses on identifying what IRQs are being used by the
devices in the computer.
IRQInfo goes through eight separate tests to identify the IRQs
used on the computer. By using a multiple-test approach, maximum
accuracy and device coverage is assured. The biggest difference
between IRQInfo and similar utilities is that IRQInfo never
assumes anything. When an IRQ is not detected, then you are told
that it wasn't.
Because of the way IRQInfo works with the computer when it runs,
it must be run from a true DOS environment with the DOS device
drivers loaded prior to running IRQInfo. This provides maximum
accuracy in detecting the system interrupts.
How a Computer Uses IRQs
========================
Computer systems use interrupts as signals between the hardware
and the software. Devices are assigned to use specific interrupt
lines (similar to "phone lines") when the board is installed. The
hardware device creates an Interrupt ReQuest (IRQ) by signalling
on the interrupt line selected by the jumper or switch. The
software using the device must be set up to watch the same
interrupt line. When the software "sees the request", it stops
whatever it is doing (it is "interrupted") and does whatever
action is required by that particular device.
NOTE: The terms "interrupt" and "IRQ" are generally
interchangeable - the board uses a particular interrupt line to
signal an IRQ. These are commonly discussed as "IRQ #", where "#"
is the number of the interrupt line used.
There are 8 interrupt lines on a IBM PC/XT, and 16 on an ISA or
EISA computer. Several of these lines are "used" internally in
the computer and are not available for add-in devices. On a
PC/XT, only IRQs 2-7 are available for add-in devices. With a
common configuration of two serial ports (IRQs 3&4), a hard disk
(IRQ 5), floppy disk (IRQ 6) and line printer (IRQ7), only IRQ 2
is free (though IRQ 7 can often be used...see the section on
"Using LPT# IRQs".)
When IBM introduced the ISA (AT computer bus), it expanded the
number of IRQs available by adding a second "interrupt
