The information in this document applies to PCs assembled using boxed Intel
P6 and NetBurst micro-architecture microprocessors. The term "boxed Intel
P6 and NetBurst micro-architecture processors" refers to processors packaged
for use by system integrators.


2) MICROCODE UPDATE OVERVIEW 

Intel P6 and NetBurst micro-architecture microprocessors may contain design
defects or errors known as errata that may cause the product to deviate from
published specifications.  Many times, the effects of the errata can be
avoided by implementing hardware or software work-arounds.  Errata and work-
arounds are documented in the appropriate processor specification update,
which can be found at www.intel.com.  Intel P6 and NetBurst micro-
architecture microprocessors include a feature called "reprogrammable
microcode", which allows certain types of errata to be worked around via
microcode updates.  The microcode updates reside in the system BIOS and are
loaded into the processor by the system BIOS during Power-On Self Test, or
POST.

System BIOS code on motherboards based on P6 and NetBurst micro-architecture
microprocessors contains microcode updates that are specific to each silicon
stepping (revision) of the processor. Integrators must ensure the microcode
update matches the processor stepping used. When the BIOS does not contain a
microcode update that matches the processor stepping, integrators must
install the latest microcode update in the BIOS before shipping the system.
Historically, systems based on P6 and NetBurst micro-architecture micro-
processors have been updated by upgrading the entire system BIOS with a new
revision of the system BIOS that contains the correct microcode update for
the processor.  However, such a process may be time consuming when
assembling and configuring many systems.

Intel has worked closely with BIOS developers to implement a processor 
update Applications Programming Interface (API), which allows just the 
microcode update within the system BIOS to be installed as needed. 
Motherboards that contain a system BIOS with the Intel-defined processor 
update API can be quickly and easily updated, if required, without need for 
a complete system BIOS upgrade. 

Table 1 contains the current microcode update revision for each processor 
stepping.

Using this utility, and the information in Table 1, integrators can 
easily verify that the correct microcode update is present in all P6 and
NetBurst micro-architecture microprocessor-based motherboards (even those
without the API). Refer to the examples below for information on determining
the processor stepping and microcode update revision contained in the
motherboard. If the microcode update requires updating, the motherboard BIOS
must contain the Intel-defined processor update API, otherwise a complete
BIOS upgrade is required from the motherboard vendor.


3) USING THE PROCESSOR UPDATE UTILITY

CHECKUP6.EXE supports systems based on Intel P6 and NetBurst micro-architec-
ture microprocessors. The Intel-defined processor update API is identical
for all P6 and NetBurst micro-architecture microprocessors.

This processor update utility, and its associated files, are distributed in 
the self-extracting archive file PUPDT608.EXE, which includes the files
listed below.  

        1) CHECKUP6.EXE --  DOS application to check the presence of a
                            valid microcode update loaded into the processor
                            by the BIOS. This utility also updates the
                            microcode update, as required, in motherboards
                            containing a BIOS that supports the Intel-
                            defined processor update API.  
        2) PEP.DAT      --  Database file containing microcode updates
        3) README.TXT   --  ASCII text help file that can be viewed from
                            CHECKUP6.EXE
        4) AUTOEXEC.BAT --  DOS batch file invoked at boot to automatically
                            run CHECKUP6.EXE
        5) AGREE.TXT    --  Software License Agreement


Uncompressing PUPDT608.EXE

Uncompress PUPDT608.EXE into a temporary directory (e.g. C:\TEMP).  Read the
license agreement in the file AGREE.TXT.  In order to uncompress the utility
and attached files (in PUP608.EXE) to a DOS bootable floppy disk, you must
agree to the license agreement.  Since this is a self-extracting archive
file, simply insert a DOS bootable floppy disk and type the following
command at the DOS prompt from the temporary directory:

   PUP608 A: <CR>

The processor update utility must be run in real mode.  Running the utility
from a "Safe Mode Command Prompt" within Windows98* and Windows95* may
cause "phantom" errors.  Booting the target system from a DOS 6.22 bootable
floppy is a good way to ensure that the target system is running in real
mode.
	
CHECKUP6.EXE will create the following files in the present working 
directory:
	
	1) STATUS.LOG  -- ASCII file that contains the messages that 
			were printed to the screen during the most recent 
			update session.


4) COMMAND LINE OPTIONS:

Before using the utility, ensure that any jumper settings on the 
motherboard are placed in the "Flash update" position to enable writing  
to the flash memory. After successfully installing a microcode update, be 
sure to return all jumpers to their orginal setting.

To invoke the utility, at the DOS prompt type the command line:

                        CHECKUP6 <CR>

When run, the utility automatically loads the appropriate microcode update
into your system BIOS if needed and returns you to the DOS prompt.  No user
intervention is needed.  However, the utility offers the option of enabling
some or all of the user prompts as needed.  This is done via command line
options.  The following command line options are available to allow a user
menu or user confirmation prompts to be displayed.

The general syntax is:

        CHECKUP6 -[flag]

where [flag] is one or more of the following:

    m   Causes the main menu to be displayed.  From this menu, the help file
	file can be displayed.  This command line option does not enable
	user promptse to confirm any permanent or temporary loading of
	microcode updates into BIOS. 

    u   Forces user confirmation.  If the utility is about to make changes
	to your system, the user will be prompted for confirmation.

    p   Specifies on the command line an external microcode update 
	database file (*.pdb).  The utility already includes the latest
        microcode updates for all production Intel P6 and NetBurst micro-architecture microprocessors.
        The syntax is "CHECKUP6 -P <file name>"  Use this command line
	option if you have a separate database file (from Intel).  Database
	files usually end with a .PDB extension.

A typical batch file syntax to force user input and use a specific PDB file
would be:

   CHECKUP6 -u -p PEP5.PDB

	or

   CHECKUP6 -p PEP5.PDB -u


5) FUNCTIONAL DESCRIPTION

Example 1: Update API is not present in the BIOS

For motherboards with a BIOS that does not have the Intel-defined processor 
update API, the utility can be used to determine that the system BIOS loads 
the latest microcode update into the processor. The utility will display the 
bootstrap processor stepping signature, which consists of the Family, Model 
and Stepping number. (Example: Stepping signature 616 can be broken into 
Family=6, Model=1, Stepping=6). Next, an indication that the API does or 
does not exist will be displayed, followed by the revision of the microcode
update loaded into the processor by the BIOS. The utility will then display 
the revision of microcode update in the database file. If this revision is 
newer than the update loaded into the processor, the utility will ask if you 
wish to temporarily load the update into the processor and boot to the hard 
disk.

 (Typical example with API NOT present in the system BIOS, but an update is
  required)

	Pentium(R) Pro processor detected.  (CPUID=x619)

	Your system will not allow this utility to permanently
	install the appropriate microcode update in your system.
	You need to contact your system manufacturer for a system
	BIOS upgrade that contains the microcode update for the 
	processor installed.  Make sure to specify the CPUID of the
	processor as shown above.

	Your system BIOS does not contain a microcode update for
	this processor.  Therefore, no microcode update was loaded.

	This utility can temporarily load the microcode update into 
	your processor.

	Would you like to temporarily load the microcode update 
	in your processor? (Y/N) y

	The update was loaded into the processor.  You need to 
	run this utility again after a system power-up or reset.
	No changes were made to the system BIOS.


	<< Please remove Floppy from Floppy Disk Drive,
	 Then press any key to boot from the hard drive >>

The above example indicates that the processor has not been loaded with a 
microcode update. A revision "D2" microcode update is available. The user 
has selected a temporary loading of the microcode update. However, this 
process must be repeated at each system boot unless the microcode update 
is permanently installed in the system BIOS.  Permanent installation of 
the microcode update when the API is not present can only be achieved by a 
system BIOS upgrade.


EXAMPLE 2: Update API is present in the BIOS

For motherboards with a system BIOS that DOES have the Intel-defined 
processor update API, the utility can be used to determine if the system BIOS
has loaded the latest microcode update into the processor and can install 
a new microcode update if required. The utility will display the bootstrap 
processor stepping, and revision of the microcode update loaded into the 
processor if it is present. Next, since the BIOS contains the API in these 
examples, the processor update utility and the API automatically determine 
if the microcode update in the system BIOS should be updated. 

 (Typical example where API is present in the BIOS, but no update is 
  required) 

	Pentium(R) II processor detected.  (CPUID=633)

	Your processor contains a microcode update, revision 34.

	The microcode update already loaded in your processor is the
	latest revision as of 12/28/98.  No changes are needed.  
	Please make sure you have the latest database file.
	

 (Typical example where API is present in the BIOS, and an update to a 
  later microcode update is required) 

	Pentium(R) II processor detected.  (CPUID=651)

	Your processor contains a microcode update, revision 29.

	The database file contains a microcode update (revision 30)
	for your processor that is more recent than the microcode
	update currently loaded in your processor.

	The microcode update was successfully loaded.
	You do not need to run this utility again, unless a new
	processor is installed or a new database file is used.



IMPORTANT: After running the utility, turn off power to the system to 
		 reboot (do not warm boot) to ensure new update is 
		 correctly initialized in the processor. Also, ensure all
		 jumpers are returned to their normal settings.



6) ERROR MESSAGES
