I/O Interface Controller
The motherboard uses the I/O controller which features:
•
Serial ports:
⎯
Internal send/receive 16-byte FIFO buffer.
⎯
Four internal 8-bit DMA options for the UART with SIR support (USI).
•
Multimode
bidirectional parallel port:
⎯
Standard mode, IBM and Centronics compatible.
⎯
Enhanced parallel port (EPP) mode with BIOS and driver support.
⎯
High-speed extended capabilities port (ECP) mode.
•
Floppy disk controller:
⎯
N82077 compatible.
⎯
Single diskette drive interface.
⎯
16-byte FIFO.
⎯
High-performance digital data separator (DDS).
⎯
PC-AT and PS/2 drive-mode support.
•
Keyboard and mouse controller:
⎯
Industry standard 8042A compatible.
⎯
General-purpose microcontroller.
⎯
8-bit internal data bus.
•
ISA Plug-and-Play compatible register set.
•
PCI PME interface.
•
Intelligent auto power management:
⎯
Shadowed write-only registers for ACPI compliance.
⎯
Programmable wake up event interface.
By default, the I/O controller interfaces are automatically configured during boot up.
The I/O controller can also be manually configured in the Setup program
.
Serial Ports
The serial port is a 16550A high speed communications port that sends/ receives 16
bytes FIFOs. You can attach a serial mouse or other serial devices directly to the
connector.
