• Both ISA and PCI expansion cards may require IRQs. System IRQs
are available to cards installed in the ISA expansion bus first, then any
remaining IRQs are available to PCI cards. Currently, there are two types
of ISA cards.
• The original ISA expansion card design, now referred to as “Legacy” ISA
card, requires you to configure the card’s jumpers manually and then
install it in any available slot on the ISA bus. To see a map of your used
and free IRQs in Windows 98, the
Control Panel
in
My Computer
, contains
a
System
icon, which gives you a
Device Manager
tab. Double-Clicking on
a specific hardware device gives you a
Resources
tab which shows
the Interrupt number and address. Double-Clicking
Computers
to see all
the interrupts and addresses for your system. Make sure that no more
than two devices use the same IRQ or your computer will result problems
when those two devices are used at the same time.
