PS/2 Keyboard and Mouse Interface
PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines
to these connectors are protected with a PolySwitch circuit that, like a self-healing
fuse, re-establishes the connection after an over-current condition is removed.
The keyboard controller supports the hot-key sequence <Ctrl><Alt><Del> for a
software reset. This key sequence resets the computer’s software by jumping to the
beginning of the BIOS code and running the Power-On Self Test (POST).
Audio Subsystem
These audio connectors are used for audio devices. You can differentiate the colour
of the audio jacks for different audio sound effects.
Line-In / RS-Out (Blue) - Line In is used for external CD player, tape player or
other audio devices. Rear-Surround Out in 4/ 5.1 channel mode.
Line-Out (Green) - Line Out, is a connector for speakers or headphones.
Mic / CS-Out (Pink) - Mic, is a connector for microphones. Center/
Subwoofer Out in 5.1 channel mode.
Management Extension Component
System BIOS
The system BIOS, from Phoenix Technology, provides ISA and PCI compatibility.
The BIOS is contained in a flash memory device on the system board. The BIOS
provides the power-on self test (POST), the system Set-up program, a PCI and IDE
auto-configuration utility, and BIOS recovery code.
PCI Auto Configuration
The PCI auto-configuration utility works in conjunction with the Set-up program to
support using PCI add-in boards in the system. When you turn on the system power
after installing a PCI board, the BIOS automatically configures interrupts, DMA
channels, I/O space, and so on. Since PCI add-in boards use the same interrupt
resources as ISA add-in boards, you must specify the interrupts used by ISA boards
in the set-up program. The PCI auto-configuration program complies with version 2.1
of the PCI BIOS specification.
IDE Auto Configuration
If you install an IDE drive in the system, the IDE auto-configuration utility
automatically detects and configures the drive for operation in the system. This
utility eliminates the need to enter the Set-up program after you install an IDE drive.
Expansion Slots
The system has two PCI bus add-in card connectors and one PCI Express x16
connector and one PCI Express x1 connector.
