ZV Port Custom Interface
The ZV (Zoomed Video) Port is a single source, point -to-point uni-directional video
bus between a PC Card socket and a VGA controller. The ZV Port complies with
CCIR601 timing to allow NTSC decoders to deliver real -time digital video straight
into the VGA frame buffer from a PC Card. The ZV Port also allows an industry
standard mechanism for transferring digital audio PCM data to a low cost DAC for
conversion to an analog signal.
In this notebook, only the bottom PC Card slo t is ZV capable.

POST Checkpoint Codes
POST is performed by the BIOS when the computer is reset or booted. POST tests
and initializes key components. When a POS T routine completes, a code is written
to I/O port address 80h. Display this code by attaching diagnostic equipment to I/O
port address 0080h.
Uncompressed Initialization Codes
Code Description
D0h The NMI is disabled. Power on delay is starting. Next, the initialization
code checksum will be verified.
D1h Initializing the DMA controller, performing the keyboard controller BAT
test, starting memory refresh, and entering 4 GB flat mode next.
D3h Starting memory sizing next.
D4h Returning to real mode. Executing any OEM patches and setting the
stack next.
D5h Passing control to the uncompressed code in shadow RAM at
E000:0000h. The initialization code is copied to segment 0 and control
will be transferred to segment 0.
D6h Control is in segment 0. Next, checking id <Ctrl><Home> was pressed
and verifying the system BIOS checksum. If either <Ctrl><Home> was
press or the system BIOS checksum is bad, next will go to checksum
code E0h. Otherwise, going to checksum code D7h.
D7h Passing control to the interface module next.
D8h The main system BIOS routine code will be decompressed next.
D9h Passing control to the main system BIOS in shadow RAM next.
Bootable Recovery Codes
Code Description
E0h The onboard floppy controller if available is initialized. Next, beginning
the base 512KB memory test.

Power On Self Test
POST Phases
Every time the system is power on, BIOS executes two types of POST routines:
System Test and Initialization Test and initialize B IOS for normal
operations.
System Configuration Verification Compare defined configuration with
hardware actually installed.
BIOS Error Reporting
If an error occurs before the display device is initialized, a series of audio beeps will
be emitted to ind icate that a fatal error is detected. Fatal errors that cause beep
codes halt the computer’s boot process.
Beeps Error Messages Description
1 Refresh Failure The memory refresh circuitry is faulty.
2 Parity Error Parity error in the base memory (the first
64KB block) of memory
3 Base 64KB Memory Failure Memory failure in the first 64KB.
4 Timer Not Operational A memory failure in the first 64KB of
memory, or Timer 1 is not functioning.
5 Processor Error The CPU generated an error.
6 8042 - Gate A20 Failure The keyboard controller (8042) may be bad.

If an error occurs after the display device is initialized, the error message is
displayed. A prompt to press <F1> will appear with the displayed error message.
