DK440LX SPECIFICATION UPDATE
10
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* RAID
por
t* card that can be installed in the onboard RAID connector will be
changed from Adaptec ARO*-1130CA-B RAID
port
card to Adaptec ARO-1130CA RAID
port
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.
4. Change to Description of Bootable Controllers
In Table 71 of Section 4.6.1, Hard Drive Submenu, the description “Bootable ISA Cards” will be changed to
“Bootable Add-in Cards.”
