I. Introduction
The Dublin u-ATX motherboard offers a time-to-market consumer desktop solution featuring the Intel Pentium-4
processor in the 478 Pin package and the Northwood Processor with the 400MHz front side bus and Intel 845
Chipset. The Dublin motherboard was designed to have highly minimized system cost. Additional H/W platform
features include AGP 4x mode, PC133 System memory, Ultra ATA/100, Low Pin Count (LPC) interface, Universal
Serial Bus and PCI audio solution with AC97 CODEC make the expensive audio add-in cards unnecessary. The
platform is also ACPI compliant and support Full-on, Stop Grant, STR, STD, and Soft-off power management
states. After all, the Dublin motherboard is a good solution for the customers who want a PC with an affordable
price.

2-3 BIOS
q Flash memory (FWH) organization
The motherboard uses a Phoenix BIOS, which is stored in the flash memory (FWH) and can be upgraded using
a disk-based program. An old version of the BIOS can be updated to the newer version using the Flash
Memory Update utility in a floppy diskette.
Address (Hex) Size Functional description
FFFFC000 – FFFFFFFF 16KB Main BIOS block#1
FFFFA000 – FFFFBFFF 8KB ESCD
FFFC0000 – FFF9FFFF 232KB Main BIOS block#2
q On-board device management
The BIOS enables or disables the devices on the motherboard with reference to the values of the contents in
CMOS setup menu. User can also disable the CMOS setup by setting the corresponding jumper (described in
III-1 Motherboard Jumper Setting section).

- ACPI S3 state : Suspend to RAM (STR)
- ACPI S4 state : Suspend to Disk (STD)
- ACPI S5 state : Soft Off (SOFF)
• Plug and play functionality normally contained in the BIOS
•
Indication LED for normal mode (Green) and suspend mode (Blinking Green) but this function is dependent
on the LED logic or BIOS control
• Supports multiple wakeup events
q Wakeup devices and operations
Wakeup devices Wakeup operations
Power switch Wakeup from Suspend mode (S1, S3 and S4) and Soft Off (S5)
USB device Wakeup from Suspend mode (S1 and S3)
