2.3.4 Accelerated Graphics Port (AGP)
The Accelerated Graphics Port (A.G.P.) is a high-performance interconnect, especially for graphic-
intensive 3D applications. A.G.P. is independent of the PCI bus and is intended for exclusive use
with graphical display devices. The A.G.P. supports AC timing for 133 MHz data transfer rates,
allowing data throughput of 533 MB/sec.
The most important feature of A.G.P. is DIME (Direct Memory Execute). DIME needs to allocate
some system memory via the O.S. to access large textures outside the local graphic memory of the
card. In order to take advantage of DIME feature, some software components should be installed or
upgraded in the system.
For Windows NT 4.0:
Upgrade to "Windows NT 4.0 Service Pack 3 or later".
For Windows 95:
Upgrade to Windows 95 OSR 2.1.
Install DirectX 6 from Microsoft.
2.3.5 Primary/Secondary IDE connectors (IDE0 and IDE1)
The motherboard has two bus-mastering IDE interfaces, which support PIO Mode 3 / 4 and Ultra
DMA 33 mode transfer. These interfaces support IDE disks, ATAPI devices (ex: CD-ROM), ZIP
and LS-120 devices. If two devices are connected to one channel, one should be set to "Master" and
the other one to "Slave" (Refer to device operation guide).
Simply connect the 40-pin IDE cable between the IDE/ATAPI devices and these connectors on the
motherboard. For a performance reason, we suggest that connect the disk drive to the primary
channel and other devices like CD-ROM to the secondary channel.
2.3.6 Floppy drive connector (FDC)
The motherboard has one floppy interface, which supports 360K, 720K, 1.2M, 1.44M, 2.88M, 3
Mode floppy drives and QIC-80 Floppy tape drive. It supports up to two devices in any capacity
with the same connector. Simply connect 34-pin floppy cable between this connector and floppy
drives.
2.3.7 Serial port connector (S1 and S2)
The two 9-pin D-Sub serial port connectors on the back panel are compatible with 16550 UART.
These ports are used for serial mouse, serial printer, fax modem …
etc. Simply connect the serial
devices to these connectors.
2.3.8 Parallel port connector (LPT)
The connector for the multi-mode parallel port is a 25-pin D-Sub connector located on the back
panel. It is used for the printer or other parallel devices. Simply connect the parallel cable between
devices and the parallel port connector.
