3.4 Installation of Expansion Slots
3.4.1 ISA & PCI Slots
There are two types of ISA expansion cards, design-Legacy and PnP (Plug & Play). For
Legacy cards you must set the cards’ jumpers manually. For Plug & Play cards, your system
will adjust the IRQs automatically. You can verify the IRQ allocation either by using
Microsoft’s Diagnostic (MSD.EXE) utility which is in the Windows directory or through the
Windows 95 resources menu.

3.4.2 Installation Procedure
The SQ578 has 7 expansion slots on-board. Four are 16-bit ISA Bus expansion connectors
and Three are 32-bit PCI expansion slots. All three PCI expansion slots accept PCI Bus
master cards and fully supported by PCI 2.1 specifications.
To install expansion cards, please read the expansion card’s documentation, which shipped
with the expansion card, for instructions.
NOTICE: Some expansion cards require an IRQ to work and may cause a conflict. There
are total of 16 IRQs but only 6 are free for expansion cards. In case of a conflict please
contact the system manufacturer for technical support.
