IRQS, DMAS, AND I/O ADDRESSES USED BY YOUR PC

IRQs used by PC
The IRQ, DMA and I/O address
mappings shown here are for a
PC with a basic configuration. The
resources used by your PC may
vary, depending upon which
accessory boards are bundled
with the PC. For information on
current use of IRQs, DMAs,and
I/O addressed by your PC, type
MSD at the MS-DOS prompt
(Windows 3.11), or use the
Device Manager (Windows 95)
DMAs used by PC
When the PC is turned off with the power button on
the front panel, the power consumption falls below 5
Watts, but is not zero. The special on/off method
used by this PC considerably extends the lifetime of
the power supply. To reach zero power consumption
in "off" mode, either unplug the PC from the power
outlet or use a power block with a switch. You should
be aware that the PC will lose its time settings within
a few days if you unplug the PC, or switch off the PC
at the power block.
