Chapter 1 System Board
1.1
Features
This high-performance system board supports the Intel Pentium II CPU running
at 266 up to 450 MHz. Integrated with the Intel 440BX system controller, which
consists of the PCI controller and the PCI/ISA IDE accelerator (PIIX4), the
AcerAltos 330 combines the new generation of Pentium II power with unmatched
graphics performance.
The System controller host bus interface supports a Pentium II processor with 66
or 100 MHz external front side bus frequency. It also provides support for
synchronous DRAM (SDRAM) 168 pin DIMMs.
The PIIX4 is a multifunction PCI device controller implementing system functions
including PCI IDE and universal serial bus (USB) host/hub. It also supports
Ultra DMA/33 synchronous DMA-compatible devices.
The system board utilizes both the ISA and the PCI local bus architectures. Two
ISA, five PCI bus slots (including one PCI/ISA shared slot), and one AGP slot
reside on the system board.
Three memory banks composed of 168-pin dual inline memory module (DIMM)
sockets support a maximum system memory of 384 MB using 128-MB DIMMs.
The system board provides additional support for the USB (Universal Serial Bus)
interface, and other standard features such as two UART NS16C550 serial ports,
one enhanced parallel port with an Enhanced Parallel Port (EPP)/Extended
Capabilities Port (ECP) feature, a diskette drive interface, and two embedded
hard disk interfaces.
