Introduction

Serial Ports
Four PC-compatible RS-232C serial ports are standard. Serial Port features include:
! 16C550-type UARTs
! UARTs are equipped with 16-byte FIFO
! Support for 115K baud rates
! Onboard voltage converters provide the RS-232C voltage levels from the single 5 volt supply
! COM2 can be jumper configured to conform with RS-485
Enhanced Parallel Port
One PC parallel port is standard. It can be used for the following applications:
! Printer port
! Channel for access to parallel port interfaced peripherals
! Digital control (output) and sensing (input) lines
! EEP, ECP, SPP, and BPP Selectable
The parallel port can be:
! Set up as the primary or secondary parallel port using the BIOS SETUP function
! Disabled to free its PC resources for other peripherals
Floppy Interface
An onboard floppy disk interface provides access to standard floppy drives. The interface supports
up to two 5.25 inch or 3.5 inch floppy drives in any combination.
IDE Interface
An onboard IDE interface provides high-speed hard disk and CD-ROM drive access. The interface
supports up to two drives. The BIOS supports hard drives up to 8.4G bytes through Logical Block
Addressing (LBA).
Compact Flash Disk
The Compact Flash interface allows you to substitute solid-state Flash memory for a conventional
rotating-media drive. Any DOS-based application, including the operating system, utilities, drivers,
and application programs, can easily be run from the Compact Flash device without modification
The Compact Flash disk is a solid-state disk system that emulates an IDE drive. It uses standard
Compact Flash disk media, similar to a PCMCIA memory card, but smaller. Insert the Compact
Flash disk media in the on-board Compact Flash socket, and use it in much the same way you
would use a removable-media hard drive. The Compact Flash drive is architecturally equivalent to
an IDE drive in your system. When installed, it becomes one of the two IDE drives supported by the
primary EIDE disk controller. It can be configured as either an IDE master or slave drive.
