System memory
•
Four 168-pin DIMM sockets
•
3.3V only DIMM DRAM configuration.
•
Synchronous 100-MHz or 66-MHz SDRAM
•
4-Mbit, 16-Mbit, 64-Mbit and 128-Mbit DRAM devices.
•
For up to 512MB standard SDRAM memory.
•
For up to 1GB Registered SDRAM DIMM memory.
•
SDRAM 64 bit data interface with ECC support.
Onboard IDE
•
Supports two PCI PIO and bus Master IDE ports.
•
Supports up to Mode 4 Timing
•
Supports 2 Fast IDE interfaces for up to 4 IDE devices, which
include IDE hard disks and CD-ROMs.
•
Supports “Ultra DMA/33” Synchronous DMA mode transfers up to
33 Mbytes/sec.
•
Integrated 8x32bit buffer for IDE PCI Burst Transfers.
Onboard I/O
•
Use WINBOND W83977TF-AW I/O chip
•
One floppy port supports up to two 3.5”or 5.25” floppy drives of
360K /720K/1.2M/1.44M/2.88M format.
•
Supports LS-120 floppy disk drive and ZIP-100 drive.
•
All I/O ports can be enabled/disabled by the BIOS setup
•
Two high speed 16550 fast compatible UARTs (COM1/COM2/
COM3 /COM4 selectable) with 16-byte send/receive FIFOs and
supports MIDI mode.
•
One enabled parallel port at I/O address 378H/278H/3BCH with
additional bi-direction I/O capability and multi-mode (SPP/EPP/
ECP) (IEEE1284 compliant).
•
Provides protection circuit to prevent damage to the parallel port when
a connected printer is powered up or operated at a higher voltage.
