Microprocessor
P54C Pentium-100 Microprocessor
The Intel Pentium Microprocessor is a 64-bit architecture with on chip Memory
Management Unit (MMU), floating point (math coprocessor) and cache memory (16K
bytes, code and data caches each contain 8 Kbytes of information) units. It has the
same functions of the Pentium-75 CPU, but provides greatly enhanced performance.
Feature includes:
- Superscalar architecture
- Separate code and data caches
- Branch prediction
- High performance floating point unit
- Enhanced 64 bits data bus
- Data integrity features
- SL technology power management features
- Multiprocessing support
- Performance monitoring
- Memory page size feature
P54XX Pentium-120/133/150/166/200 Microprocessor
The Intel Pentium-120/133/150/166/200 CPU is the same as Pentium-75 with
different running speed.
P55C-133/166/200 Microprocessor
The Intel P55C-133/166/200 Processor is more accurate and aggressive than the
P54C processor and the P55C CPU has built in MMX (MultiMedia eXtension enable)
Technology Architecture.

PC CARD 95 (CardBus) Interface Controller - TI PCI1131
TI CardBus Interface Controller 1131 implements the
PCMCIA 2.0/JEIDA 4.1 standard. It contains the following functions:
l PCI interface Specification 2.1
l Supports Zoom Video Mode
l PCMCIA dual-socket interface
l Five programmable memory windows per socket
l Two I/O windows per socket
l ATA disk interface support
l Programmable Suspend mode
l Automatic flash memory timing support
l ExCA-compatible
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 slot 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 POST 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
D0h
D1h
D3h
D4h
D5h
D6h
D7h
D8h
D9h
Description
The NMI is disabled. Power on delay is starting. Next, the initialization
code checksum will be verified.
Initializing the DMA controller, performing the keyboard controller BAT
test, starting memory refresh, and entering 4 GB flat mode next.
Starting memory sizing next.
Returning to real mode. Executing any OEM patches and setting the
stack next.
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.
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.
Passing control to the interface module next.
The main system BIOS routine code will be decompressed next.
Passing control to the main system BIOS in shadow RAM next.
Bootable Recovery Codes
Code
E0h
Description
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
System Configuration Verification
Test and initialize BIOS for normal
operations.
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 indicate that a fatal error is detected. Fatal errors that cause beep
codes halt the computer’s boot process.

Description
The memory refresh circuitry is faulty.
Parity error in the base memory (the first
64KB block) of memory
Memory failure in the first 64KB.
A memory failure in the first 64KB of
memory, or Timer 1 is not functioning.
The CPU generated an error.
The keyboard controller (8042) may be bad.
The BIOS cannot switch to protected mode.
The CPU generated an exception interrupt.
The system video adapter is either missing
or its memory is faulty. It’s not a fatal error.
The ROM checksum value does not match
the value encoded in the BIOS.
The shutdown register for CMOS RAM has
failed.
The external cache is faulty.

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.

Explanation
Gate A20 on the keyboard controller (8042) is not
working. Replace the 8042.
Errors in the address decoding circuitry.
Hard disk drive C: does not respond. Check the C:
hard disk type in the Standard Setup.
Hard disk drive C: does not respond. Replace the hard
disk.
Cache memory is defective. Replace it.
Most ISA computers include two timers. There is an
error in Timer 2.
CMOS RAM is powered by a battery. The battery
power is low. Replace the battery.
After CMOS RAM values are saved, a checksum value
is generated for error checking. The previous value is
different from the current value. Run the BIOS Setup.
The values stored in CMOS RAM are either corrupt or
nonexistent. Run the BIOS Setup.
The video type in CMOS RAM does not match the type
detected by the BIOS. Run the BIOS Setup.
The amount of memory is different from the amount in
CMOS RAM.
Run Standard Setup to set the date and time in CMOS
RAM.
Hard disk drive D: does not respond. Check the D:
hard disk type in the Standard Setup.
Hard disk drive D: does not respond. Replace the hard
disk.
The boot disk in floppy disk A: is corrupt. It can not be
used to boot the computer. Use another boot disk and
follow the screen instructions.
Some computers require a video switch be set to either
color or monochrome. Turn the computer off, set the
switch, then power on.
Error in the DMA controller.
Error in the first DMA channel.
Error in the second DMA channel.
The BIOS can not communicate with the floppy disk
drive controller. Check all appropriate connections after
the computer is powered down.
The BIOS can not communicate with the hard disk
drive controller. Check all appropriate connections after
the computer is powered down.
Interrupt channel 1 failed POST.
Interrupt channel 2 failed POST.

Parity Error ???
The BIOS can read the disk in the floppy disk drive A:,
but can not boot the computer. Use another boot disk.
The keyboard lock is engaged. The computer must be
unlocked to continue.
There is a timing problem with the keyboard. Set the
keyboard option in Standard Setup to Not Installed to
skip the keyboard POST routines.
There is an error in the keyboard connector.
Can not find a bootable sector on either disk drive A: or
hard disk drive C:. The BIOS calls INT 18H which
generates this message. Use a bootable disk.
Parity error in memory installed in an expansion slot.
Parity error in motherboard memory.
Parity error in system memory at an unknown address.
