Phoenix MicroATX Express – Installation Guide

NOTE

ATA-66 and ATA-100 are faster timings and require a specialized cable (80-conductor) to reduce
reflections, noise, and inductive coupling.

The Parallel ATA IDE interface also support ATAPI devices (such as CD-ROM drives).
The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS)
translation modes. The drive reports the transfer rate and translation mode to the BIOS. The Phoenix
MicroATX Express supports Laser Servo (LS-120) diskette technology through the Parallel ATA IDE
interface. The BIOS supports booting from an LS-120 drive.

NOTE

The BIOS will always recognize an LS-120 drive as an ATAPI floppy drive. To ensure correct operation, do
not configure the drive as a hard disk drive.

Serial ATA Interfaces

The Phoenix MicroATX Express features four independent Serial ATA ports with a theoretical maximum
transfer rate of 300 MB/s per port. One device can be installed on each port for a maximum of four Serial
ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel IDE, which
supports a master/slave configuration and two devices per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the operating system.

NOTE

Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies
equipped with low-voltage power connectors.

Serial Ports

Up to six high speed RS-232 serial ports 16 Bytes FIFO (16550/16550D). COM2 optional RS-232 IrDA
and COM1 optional RS-422/485. COM1 and COM2 are standard, other ports are optional.

Parallel Port

One bi-directional parallel port. EPP/ECP mode compatible.

Keyboard/Mouse Port

One mouse/keyboard combined PS/2 connector

USB Interfaces

Eight Universal Serial Bus connectors. USB 1.1 and USB 2.0 compliant.

On-board Ethernet

One (optional two) PCI Express based Gigabit Ethernet controllers (Intel 82573L).

On-board Buzzer

Audio

Intel HD Audio. Microphone In, Stereo Line In and Out, Aux In and CD In.
