8050D N/B Maintenance transmits data to a TV output (analog composite, s-video or RGB). The device accepts data over one 12-bit wide variable voltage data port which supports five different data format including RGB and YcrCb. The TV-Out processor will perform non-interlace to interlace conversion with scaling and flicker filters, and encode the data into any of the NTSC or PAL video standards. The scaling and flicker filter is adaptive and programmable to enable superior text display.

Pin Descriptions of Major Components 5.1 Intel Pentium M(Banias) Processor(1) Signal Name A[31:3]# A20M# Type Description I/O A[31:3]# (Address) define a 2 32 -byte physical memory address space. In sub-phase 1 of the address phase, these pins transmit the address of a transaction. In sub-phase 2, these pins transmit transaction type information. These signals must connect the appropriate pins of both agents on the Intel Pentium M processor system bus.

8050D N/B Maintenance 7. Maintenance Diagnostics 7.1 Introduction Each time the computer is turned on, the system BIOS runs a series of internal checks on the hardware. This power-on self test (post) allows the computer to detect problems as early as the power-on stage. Error messages of post can alert you to the problems of your computer.If an error is detected during these tests, you will see an error message displayed on the screen.

8050D N/B Maintenance 7.2 Diagnostic Tool for Mini PCI Slot : The Mini PCI DOG killer card is a single-step debug tool which utilizes Mini PCI interface (Type III A) and is able to hold a PCI bus cycle so that address, data and control bus states on PCI bus can be inspected. Especially, the tool can help an engineer trace address/data bus for BIOS read cycles as soon as power on and debug open or short circuit problems easily. Usually, this sort of problem will make a PC motherboard fail to boot.
