Chipset ------- Apollo Pro 133 chipset: VT82C693A, VT82C596B. System memory ------------- Provides three 168 pin 3.3V buffered/unbuffered 66/100/133MHz DIMM sockets. Supports both 66/100/133MHz SDRAMs with SPD and 66MHz EDO DIMMs. Minimum memory size is 8MB, maximum memory size is 768MB. SDRAM 64 bit data interface with ECC support. On-board IDE ------------ Supports two PCI PIO and Bus Master IDE ports. Two fast IDE interfaces supporting four IDE devices including IDE hard disks and CD-ROM drives. Supports up to mode 4 timing. Supports "Ultra DMA/33" Synchronous DMA mode transferring up to 33 Mbytes/sec. Supports "Ultra DMA/66" Synchronous DMA mode transferring up to 66 Mbytes/sec. Integrated 16x32bit buffer for IDE PCI Burst Transfers. On-board I/O ------------ Use Winbond W83977EF super I/O chip. One floppy port supporting up to two 3.5" or 5.25" floppy drives with 360K/720K/1.2M/1.44M/2.88M format. Two high speed 16550 fast compatible UARTs(COM1/COM2/COM3/COM4 selective) with 16-byte send/receive FIFOs. One enabled parallel port at the I/O address 378H/278H/3BCH with additional bi-direction I/O capability and multi-mode as SPP/EPP/ECP (IEEE 1284 compliant). Circuit protection provided, preventing damage to the parallel port when a connected printer is powered up or operates at a higher voltage. Supports LS-120 floppy disk drive and Zip drive. All I/O ports can be enabled/disabled in the BIOS setup. AGPSLOT ------- Supports an 2X AGP card. Advanced features ----------------- PCI 2.1 Specification compliant. Provides Trend ChipAwayVirus®On Guard and PC-Cillin software with killing virus function. Provides two USB ports, on-board PS/2 mouse and PS/2 keyboard ports. Provides infrared interface. Support PC99 color-coding connector Specification Supports Windows 95/98 software power-down. Supports wake-up on LAN and wake-up on internal/external modem. Supports auto fan off when the system enters suspend mode. Provides on-board 3.3V regulator to support ATX power supply without 3.3V output. On-board W83782D supports system monitoring (monitors system temperature, CPU temperature, voltages, chassis intrusion and fan speed). (manufacturing option) Provides management application such as ManageEasy. Supports keyboard password power-on function. Protects the system BIOS from being attacked by severe virus such as CIH, by enabling "FlashWrite Protect" in CMOS setup or closing the Jumper "JAV". BIOS ---- Licensed advanced AWARD BIOS, supports flash ROM with 2M bit memory size, plug and play ready. Supports IDE CD-ROM or SCSI boot up. Green function -------------- Supports ACPI (Advanced Configuration and Power Interface) and ODPM (OS Directed Power Management). Supports three green modes: Doze, Standby and Suspend. Expansion slots --------------- 2 ISA slots and 5 PCI slots. 1 AGP Slot.
