Overview
The NT928 P2BXD is a Pentium II based mainboard that utilizes Intel’s
newest 82440BX chipset with in an ATX size. This mainboard is designed for
both Pentium II and Celeron CPU’s It supports new architectures such as
high speed AGP graphic port, Ultra DMA/ 33, Bus Master IDE, SDRAM
memory and is expandable to a maximum of 1Gbyte of memory.
In addition to above features, NT928 P2BXD implements most advanced
technology such as synchronous Switching voltage regulator, CPU thermal
protection, CPU fan monitoring, System voltage monitoring, Over
current protection, Modem Wake Up, Keyboard power on, PS/2 mouse
power on, Debug sensor LED on board and user-friendly jumper-less
CPU speed selection.
The most unique feature of the NT928 P2BXD is its capability to debug
possible installation and peripherals faults onboard. When the CPU, DRAM,
FDD, or VGA cards have not been properly installed, a DIY user can isolate
problems through reading the Debug Sensor LED and instructions in the
manual. To professional system test engineers or maintenance engineers,
the Debug Sensor works as a Port 80 Debug Card for testing and
maintenance in lieu of the 80 Port Debug card.

B. Smart Debug On Board
When the CPU module, DRAM, Cache RAM, FDD or VGA cards have not
been properly installed, users can isolate those basic problems through the
Debug Sensor LED and instructions from the manual. For professional
system engineers or maintenance engineers, the Debug Sensor works in the
same fashion as a Port 80 Debug Sensor Card.
NOTE: This is an example of functionality. For detail, see technical section.
