(2) Hard Disk Connectors: IDE1/ IDE2
The motherboard has a 32-bit Enhanced PCI IDE Controller that provides PIO
Mode 0~4, Bus Master, and Ultra DMA 33/ 66/ 100/ 133 functionality. It has
two HDD connectors IDE1 (primary) and IDE2 (secondary).
The IDE connectors can connect a master and a slave drive, so you can connect
up to four hard disk drives. The first hard drive should always be connected to
IDE1.
(3) Peripheral Component Interconnect Slots: PCI1-3
This motherboard is equipped with 3 standard PCI slots. PCI stands for
Peripheral Component Interconnect, and it is a bus standard for expansion
cards. This PCI slot is designed as 32 bits.
(4) Accelerated Graphics Port Slot: AGP1
Your monitor will attach directly to that video card. This motherboard sup-
ports video cards for PCI slots, but it is also equipped with an Accelerated
Graphics Port (AGP). An AGP card will take advantage of AGP technology to
improve video efficiency and performance, especially with 3D graphics.
(5) Communication Network Riser Slot: CNR1 (optional)
The CNR specification is an open Industry Standard Architecture, and it de-
fines a hardware scalable riser card interface, which supports modem only.
(6) Serial ATA Connector: JSATA2/JSATA3/(JSATA1: optional)
The motherboard has a PCI to SATA Controller with 2 channels STAT interface.
It satisfies the SATA 1.0 spec and can transfer data with 150 MB/s speed.
