System Setting by Jumper
The mainboard offers a set of jumper settings to facilitate clock frequency
adjustment and some important selections.
CPU Frequency Selection
According to CPU’s specification, set CPUs clock speed carefully. The
following illustration lists the jumper settings for the PentiumII CPUs:
JP2 JP3 JP4 JP5
PentiumII 133MHz =2x66MHz
PentiumII 200MHz =3x66.66MHz
PentiumII 333MHZ=5x66MHZ

Note: You must shut down the power
supply first when you
want to clear the CMOS.
Memory Configuration
The P6I440LX/DP Legend IV mainboard supports up to four 168PIN 3.3V un-
buffered DIMM, provides a flexible size from 8MB up to 512MB SDRAM
memory or from 8MB up to 1GB EDO memory. The following set of rules
allows for optimum configurations.
Rules for populating a 440LX/DP Legend IV memory array:
DIMM sockets can be populated in any order. However, to take advantage of
potentially faster MA timing it is recommended to populate sockets in order.
SDRAM and EDO DIMMs can be mixed within the memory array.
The DRAM Timing register, which provides the DRAM speed grade
control for the entire memory array, must be programmed to use the
timings of the slowest DRAMs installed (Please refer to "Chipset
Features Setup" of BIOS).
Possible EDO DIMM memory size is 8MB, 16MB, 32MB, 64MB,
128MB, 256MB in each DIMM socket.
Possible SDRAM memory size is 8MB, 16MB, 32MB, 64MB, 128MB,
256MB in each DIMM socket.
Wide SCSI Selection
JP25 decides the on-board SCSI controller
whether to work in ultra wide SCSI mode or
ultra narrow SCSI mode. Please see the table
listed below.

2. If you want to power off your system, just push once*again the button.
*Note:If you change “soft-off by PWR-BTTN” from default “Instant-off” to “Delay
4 Secs” in BIOS Setting, you will have to press the power button for more than
4 seconds before the system power down. For details, please refer to Page 4-9.

you can select any one of the two slots to install the CPU,
while another slot is for GTC (GTL Terminator Card). It's
necessary to install GTC when single CPU mode is
selected.
LAN On-board LAN I/O Connector. The on-board LAN adapter
occupies PIRQB of the PCI interrupter.
AGP For AGP cards. Since the on-board LAN occupies PIRQB
of PCI interrupter, you must select PIRQA for AGP Card
to avoid the resource’s conflicting.
PCI1 A PCI slave device can be installed, such as VGA card
which does not need interrupter. A PCI master device also
can be installed which needs PCI interrupter, such as a
LAN adapter. If a master device is installed, PIRQA must
be selected and there's no AGP card available.
PCI2 For those PCI slave devices which do not need PCI
interrupter.
PCI3 For those PCI slave devices which do not need PCI
interrupter.
PCI4 It's the same as PCI1 except the PCI interrupter should be
set to PIRQD when a master device is installed. In most
cases, PCI4 combining with the RAID port slot is used for
RAID port card (See RAID port).

adapter.
This RAID port option by adding the Adaptec ARO-1130
adapter can support:
Bus Master DMA
Up to 133 Mbyte/Sec Burst rate
RAID 5, 1, 0 and 0/1
Fully Netware 3.11, 3.12, 4.x & WinNT
3.51/4.0 supported by Adaptec
ISA 1, 2, 3 General using for ISA cards.
DIMM 1-2, 3, 4 Memory for SDRAM or EDO.
Narrow SCSI For ultra narrow SCSI peripherals. Be sure the red side of
the cable should align to the end of the connector which is
signed with " ".
Wide SCSI For ultra wide SCSI peripherals.
Note1:Ultra narrow SCSI peripherals and ultra wide SCSI
peripherals can be used at the same time.
Note2:You must assign a different SCSI ID to each device
on the SCSI bus connected to the system board. See your
SCSI device documentation for directions on how to
determine the ID and change it.
Ultra Wide SCSI devices connected to this mainboard’s
SCSI connector can be assigned ID from 0 to 15 (for 68
pin Wide SCSI connection). Normally, ID7 will be used
by the on-board host.
The SCSI ID0 is the best one for SCSI hard disk to be
used as your computer’s boot device; ID1 is best reserved
for a secondary SCSI hard disk. (Only when you use the
SCSI hard disks and devices.)
