System Overview 1-5
After all legacy cards have been configured by the operating system or with
the ICU, the computer automatically assigns any required memory space, IRQ
lines, and DMA channels to any installed Plug and Play ISA expansion cards
and PCI expansion cards the next time the computer is rebooted. Chapter 4,
“Using the ISA Configuration Utility,” in the
Dell Precision WorkStation 610 Mini
Tower Systems User’s Guide
describes the ICU and provides instructions for
using it to configure the computer.
There are seven expansion-card connectors (see Figure 1-4) on the system
board. Expansion-card connectors PCI1 through PCI5 support 32-bit PCI
expansion cards; expansion-card connector AGP supports a 32-bit 2X AGP
expansion card; and expansion-card connector ISA1 can accommodate an 8- or
16-bit ISA expansion card.
NOTES: Connector ISA1 shares expansion-slot space with connector PCI5.
Therefore, only one card of either type can be installed in this slot.
PCI4 has a connector extension to support a PCI RAID controller (see
Figure 1-11 for the location of the PCI connectors).
