DK440LX SPECIFICATION UPDATE
SPECIFICATION CHANGES
The Specification Changes listed in this section apply to the DK440LX Motherboard Technical Product
Specification (Order Number 682717). All Specification Changes will be incorporated into a future version of
that specification.
1.
Revision of External Battery Specification
The estimated life of the external battery when the system is not plugged into an AC power source has been
changed. Paragraph 3 of Section 1.8.7, Real-Time Clock, CMOS SRAM, and Battery will be replaced in its
entirety as follows:
An external coin-cell battery powers the real-time clock and CMOS memory. When the computer is not
plugged into a wall socket, the battery has an estimated life of one year. When the computer is plugged in,
the 3 V standby current from the power supply extends the life of the battery. The clock is accurate to ± 13
minutes/year at 25 ºC with 5 V applied.
2.
Revision of Section 1.15.5, Adaptec* RAIDport*
The name of the Adaptec* RAIDport* card that can be installed in the onboard RAID connector will be
changed from Adaptec ARO*-1130CA-B RAIDport card to Adaptec ARO-1130CA RAIDport II card. This card
supports only RAID levels 0 and 1. Reference to support for level 0/1 will be removed.
3.
Support for 333 MHz Pentium II Processors
The motherboard supports 333 MHz Pentium II processors. Section 1.4, Microprocessor, will be modified to
add 333 MHz to the list of supported processor speeds.
333 MHz has been added to the list of speeds that can be selected in the BIOS Setup program configure
mode and Table 58, Maintenance Menu, will be updated to include that speed.
BIOS revision 4D4KL0X0.86A.0016.P07.9801051509 or later is required for the motherboard to properly
support a 333 MHz processor.
Note: Conformity with FCC open chassis emission standards was verified with processor speeds up to
300 MHz, the highest processor speed available at the time the motherboard was introduced.
Higher speed processors may increase system electro-magnetic emissions. It is the responsibility of the
system integrator to verify that a system based on this motherboard and any new higher speed processor,
including the newly announced 333 MHz Pentium II processor, complies with EMC emission standards.

ERRATA
1.
LS-120 Drive Does Not Work as Expected in Windows* 95
PROBLEM: After restarting Windows* 95 from MS-DOS* mode, the system BIOS does not configure the
diskette parameter table correctly if an LS-120 drive is the only floppy drive in the system.
IMPLICATION: Windows 95 will report the LS-120 drive as a hard drive instead of a floppy drive and will report
a floppy drive available as Drive A. If drive A is subsequently accessed, the system will lock up. The
problem does not occur if a 1.44 MB 3-1/2” floppy drive is also present as either drive A or drive B.
WORKAROUND: None.
STATUS: This erratum was fixed in BIOS revision 4D4KL0X0.86A.0012.P04.
2.
Serial Mouse Activity Does Not Wake System After APM Shutdown
PROBLEM: The system BIOS does not recognize activity from a serial mouse as an APM event.
IMPLICATION: The system will not be restored from a power-managed state until keyboard activity occurs.
WORKAROUND: The system BIOS does recognize activity from a PS/2* style mouse.
STATUS: This erratum will not be fixed.
3.
Stuck or Depressed Key During POST May Cause System Hang
PROBLEM: The BIOS is unable to detect when a key on the keyboard is stuck or depressed during Power
On Self Test (POST).
IMPLICATION: If a key is stuck or depressed during POST, the system BIOS will continue to read data from
the keyboard, resulting in a system hang condition.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
4.
System BIOS Does Not Detect ECC Memory Errors
PROBLEM: The system BIOS does not detect when a single or double bit ECC memory error is identified by
the memory controller.
IMPLICATION: For single bit errors, the error will be corrected based on the memory checkbits. The
corrected data will be passed to the system by the controller, but the error will not be signaled to the system
BIOS.
For double-bit errors identified during run time, no error will be signaled to the system BIOS and the system
will not be halted. The erroneous data will be passed to the system by the controller.
Because these errors are not detected by the system BIOS, they will not be flagged in the DMI log stored in
non-volatile flash memory and the user will not receive information from this log that could be useful in
isolating a failing memory module.
12
DK440LX SPECIFICATION UPDATE
WORKAROUND: None.
STATUS: This erratum was fixed in BIOS revision 4D4KL0X0.86A.0014.P06.
5.
Onboard SCSI Controller Identifies Tape Drive as Hard Drive
PROBLEM: The onboard SCSI controller may incorrectly identify an attached SCSI tape backup drive as a
hard disk drive.
IMPLICATION: The tape drive is not accessible, although it appears in the BIOS Setup Boot Menu.
WORKAROUND: None.
STATUS: This erratum was fixed in BIOS revision 4D4KL0X0.86A.0018.P09.
6.
System Cannot Recover BIOS From LS-120 Drive
PROBLEM: The permanent system BIOS code stored in the boot block section of the BIOS flash memory
device does not include initialization code for the LS-120 drive.
IMPLICATION: If the system requires a BIOS recovery because the BIOS was corrupted during an update,
that BIOS recovery cannot be performed from an LS-120 drive. An attempt to recover the BIOS from an
LS-120 drive, using the BIOS recovery setting of the configuration jumper, will result in a media device error.
WORKAROUND: Temporarily replace the LS-120 drive with a standard diskette drive to perform the BIOS
recovery.
STATUS: This erratum will not be fixed.
7.
SCO* UnixWare* Will Not Install From Onboard SCSI Channel B
PROBLEM: The SCSI driver for the SCO* UnixWare* operating system disables Channel B during installation
of the operating system. Unixware version 7.0 is not affected by this erratum.
IMPLICATION: An attempt to install from a SCSI device attached to onboard SCSI channel B will fail with the
error message: “Warning: adsl: Command timed out.”
WORKAROUND: None.
STATUS: This erratum will be fixed in a future revision of the SCSI driver.
8.
Advanced Power Management May Suspend System During
CD-ROM Playback
PROBLEM: ATAPI devices (such as CD-ROM and DVD drives) do not reset the inactivity timer that is used
by Advanced Power Management to determine when to place the system into suspend mode.
IMPLICATION: When playback of an audio CD or a DVD file is the only system activity, the system will go into
suspend mode when the inactivity timer expires.
WORKAROUND: Temporarily disable the Low-power standby and Shut off monitor options on the Display
Properties, Screen Saver menu. This menu is available from the Windows* 95 Control Panel.
STATUS: This erratum will not be fixed.
13
DK440LX SPECIFICATION UPDATE
9.
System Will Not Boot with Network as First Boot Device
PROBLEM: The feature allowing the system to boot from the network is not implemented. After the attempt
to boot from a network device selected as the first boot device fails, the system BIOS does not attempt to
boot from any additional boot devices specified in the BIOS Setup program.
IMPLICATION: If Network boot is selected as the first boot device, the system will hang.
WORKAROUND: Remove Network boot from the boot sequence.
STATUS: This erratum was fixed in BIOS revision 4D4KL0X0.86A.0021.P10.
10.
System BIOS Does Not Recognize Hard Drives Larger Than 8.4 GB
PROBLEM: The system BIOS does not include hard drive parameters to recognize drives larger than 8.4 GB.
IMPLICATION: An installed hard drive larger than 8.4 GB will not be available to the operating system.
WORKAROUND: None.
STATUS: This erratum was fixed in BIOS revision 4D4KL0X0.86A.0021.P10.
11.
BIOS Setup Does Not Support Changing User Password or
Unattended Start in User Mode
PROBLEM: Although the BIOS specification calls for the user password to be changed and the unattended
start feature to be enabled or disabled in User Mode the current BIOS does not allow this.
IMPLICATION: The administrative password must be entered in order for the user to modify either of these
options.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
12.
BIOS Does Not Release IRQ if No Mouse is Present
PROBLEM: The BIOS does not release the default IRQ12 used by a PS/2* mouse even if no mouse is
detected in the system.
IMPLICATION: Some system resources may not be assigned an IRQ in a system with a large number of
peripherals.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
14
DK440LX SPECIFICATION UPDATE
13.
System Using 3-Mode Floppy Drive Cannot Read XDF Format
Diskettes
PROBLEM: The buffer area that stores floppy drive parameters does not have room to store the speed
information to allow a 3-mode floppy drive to read a diskette in the XDF format.
IMPLICATION: A system that has a 3-mode floppy drive cannot be used to install a program or operating
system, such as PC-DOS 7.0, that is distributed on XDF format diskettes.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
14.
System With 3 Mode Diskette Drive Will Not Format Unformatted
Floppy Disk
PROBLEM: The BIOS does not support formatting unformatted diskettes with a 3-mode diskette drive. The
operation will terminate with the message, “Track0 Not Found.” Previously formatted diskettes can be
reformatted in the drive.
IMPLICATION: Unformatted diskettes will have to be formatted in another system before they can be used.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
15.
Option to Scan User Flash Area Does Not Work
PROBLEM: The option to scan the user flash area at system boot and execute a binary file stored there is not
implemented in the BIOS.
IMPLICATION: The user will not be able to use this function.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
16.
BIOS Does Not Halt System After Multi-bit ECC Error
PROBLEM: When a multi-bit ECC error is detected by the BIOS a record of the error is entered into the
management information log but the system is not halted.
IMPLICATION: The erroneous data will be passed to the system by the memory controller.
Single-bit errors are detected and corrected by the memory controller and entered into the management
information log.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
15
DK440LX SPECIFICATION UPDATE
17.
The System BIOS Does Not Release Upper Memory When USB
Legacy Support Is Disabled
PROBLEM: The upper memory area used to provide legacy support for USB keyboards and mice is not
released by the system BIOS even when USB Legacy Support is disabled in the BIOS Setup program.
IMPLICATION: Users who need to load drivers or TSR programs in upper memory blocks may not have
enough space to load them.
WORKAROUND: None.
STATUS: This erratum will not be fixed.

SPECIFICATION CLARIFICATIONS
The Specification Clarifications listed in this section apply to the DK440LX Motherboard Technical Product
Specification (Order Number 682717). All Specification Clarifications will be incorporated into a future version
of that specification.
1.
Network Operating System May Report Lost Hardware Interrupts
Because of an interaction between the Intel 82093AA I/O Advanced Programmable Interrupt Controller
(IOAPIC) and the Novell Netware* operating system, Novell may post a message to the screen that reports
lost or spurious hardware interrupts. These messages and the time required to process them may cause
some small increased processor latency, but they have no other impact for the end user. Certain debug
hooks built into the operating system may not operate correctly and this could affect application developers.
2.
The Intel® Celeron™ Processor
While the Intel Celeron™ processor uses the same P6 microarchitecture as the Pentium  II processor,
there are some differences. No qualification or compatibility testing has been performed using the Celeron
processor and the BIOS does not contain support for this processor. A Celeron processor will be identified as
a Pentium II processor by the system. While the Celeron processor may appear to work in the motherboard,
the reliability of operation is not known.

DOCUMENTATION CHANGES
The Documentation Changes listed in this section apply to the DK440LX Motherboard Technical Product
Specification (Order Number 682717). All Documentation Changes will be incorporated into a future version
of that specification.
1.
Revision of Section 3.4, PCI IDE Support
Section 3.4, PCI IDE Support, will be replaced in its entirety as follows:
If Auto is selected as a primary or secondary IDE device (see Section 4.2.2) in Setup, the BIOS automatically
sets up the two local-bus IDE connectors with independent I/O channel support. The IDE interface supports
hard drives up to PIO Mode 4 and recognizes ATAPI devices, including CD-ROM drives, tape drives and
Ultra DMA drives (see Section 6.2 for the supported version of ATAPI). Add-in ISA IDE controllers are not
supported. The BIOS determines the capabilities of each drive and configures them so as to optimize
capacity and performance. To take advantage of the high-capacity storage devices, hard drives are
automatically configured for logical block addressing (LBA) and to PIO Mode 3 or 4, depending on the
capability of the drive. To override the autoconfiguration options, use the specific IDE device options in
Setup. The ATAPI specification recommends that ATAPI devices be configured as shown in Table 54.
2.
Revision of Section 6.3, BIOS Beep Codes
Section 6.3, BIOS Beep Codes, will be replaced in its entirety as follows:
BIOS BEEP CODES
Whenever a recoverable error occurs during Power-On Self Test (POST), the BIOS displays an error
message describing the problem. The BIOS also issues a beep code (one long tone followed by two short
tones) during POST if the video configuration fails (no card installed or faulty) or if an external ROM module
does not properly checksum to zero.
An external ROM module (e.g video BIOS) can also issue audible errors, usually consisting of one long tone
followed by a series of short tones. For more information on the beep codes issued, check the
documentation for that external device.
There are several POST routines that issue a POST Terminal Error and shut down the system if they fail.
Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error,
writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of
the screen (using both mono and color adapters).
If POST completes normally, the BIOS issues one short beep before passing control to the operating system.

Change to Description of Manufacturing Options
In Section 1.2, Manufacturing Subsystem Options, paragraph one will be replaced in its entirety as follows:
The following are manufacturing subsystem options. Not all manufacturing options are available in all
marketing channels. Please contact your Intel representative to determine what manufacturing options are
available to you.
4.
Change to Section 3.7, Desktop Management Interface
In Section 3.7, Desktop Management Interface (DMI), paragraph 2 will be replaced in its entirety as follows:
Intel can provide system manufacturers with a utility that programs system and chassis-related information
into the DMI space in Flash memory. The utility is used to program the BIOS during system manufacturing,
so that the BIOS can later report this information. Once written, this information cannot be overwritten by the
end user.
