512 bytes of E²PROM with Device Drivers.
Audio:
Integrated Soundblaster/Direct sound AC97 controller
Line In/Out, Microphone and CD in.
Note: CD in and Line in share the same pins and are therefore
mutually exclusive.
Monitoring:
CPU Core(1.05 to 1.6V), North Bridge Core(2.5), 3V3 and 5V voltage
monitors
Two on board thermistors for system thermal monitoring
Hardware Watchdog timer with configurable timeout.
Software enabled/disable through an IO port. The time-out results in a
system Reset. Device Driver support is available.
Power monitoring of the +5 volt rail included in the Reset circuit. Reset
generated if the rail falls below 4.65 volts.
Communications:
Quad USB Ver 1.x Compliant
Two 16C550 compatible serial ports at TTL level signalling.
Note: Base board must provide RS232 or RS485 transceivers.
One IR port. This is shared with the second serial port UART.
Parallel port with Bi-directional, EPP & ECP.
Floppy interface with support for dual 1.44MB FDD
Note: the floppy or parallel port are an option that is determined at
boot time by strapping a pin on the base board ie if floppy port
selected then there is no parallel port and vice-versa)
PS/2 compatible keyboard and mouse port. Connector located on
baseboard
Miscellaneous:
PC standard Real Time Clock is integrated into the South Bridge. Due
to height constraints, the battery has to be located on the host board.
Speaker, Reset switch, Power Switch, Hard Disk Activity LED,
Suspend Switch and external Lithium coin cell are all supported and
located on the base board.
Expansion Bus:
As per ETX specification, 4 connectors (X1-X4)
The host board supports four standard 5V 32 bit 33MHz PCI slots. The
PCI is V2.2 compliant.
ISA Expansion supports three standard 16-bit ISA slots.
Connector X1 provides the PCI Bus, USB and Audio
Connector X2 provides the ISA Bus
Connector X3 provides the VGA, LCD, COM1&2 (TTL) LPT1, Mouse
and Keyboard.
Connector X4 provides the Ethernet (non-isolated), 2xEIDE (4 drives),
utilities signals and power management and control.
