PT-5IVL SYSTEM BOARD HARDWARE SETUP
4. HARDWARE SETUP
4.1 UNPACKING
The system board package should contain the following parts :
 The PT-5IVL system board.
 OPERATION MANUAL.
 Cable set for IDE and I/O device.
4.2 HARDWARE CONFIGURATION
Before the system board is ready to operate, the hardware must be configured to allow for various functions
within the system. To configure the PT-5IVL system board is a simple task, only a few jumpers, connectors,
cables and sockets needs to be selected and installed. (For the detailed locations of each component please refer
to the "system board layout figure" which appears in page 3-1.)
4.2.1 DRAM INSTALLATION
The PT-5IVL system board will support two banks main memory (bank 0 and bank 1) on board (using four 72-
Pin SIMM socket, SIMM 1-4), each bank could be single-sided or double-sided, 8MB up to 128 MB of local
memory can be attained. Supports both standard fast page mode (FPM) and Extended Data Out (EDO) memory.
(Note that this system board doesn't support 3.3V SDRAM) The speed of FPM DRAMs must be used 70ns or
faster than 70ns, the speed of EDO DRAMs must be used 60ns or faster than 60ns.
The usable SIMM modules are : (Note : S = Single-sided , D = Double-sided)
1MBx32(36)-S ( 4MB) ,1MBx32(36)-D ( 8MB),
2MBx32(36)-S ( 8MB) ,2MBx32(36)-D (16MB),
4MBx32(36)-S (16MB) ,4MBx32(36)-D (32MB).
The following table provides the possible combinations for DRAM memory installation.
Bank 0 Bank 1 Bank 0 Bank 1
SIMM1 and SIMM2 SIMM3 and SIMM4 SIMM1 and SIMM2 SIMM3 and SIMM4
Single-sided Single-sided Double-sided Single-sided
Single-sided Double-sided Double-sided Double-sided
Bank can be populated in any order (bank 0 does not have to be populated before bank 1). Within any given
bank, the SIMMs must be the same size. Among the two banks, SIMM densities can be mixed in any order.
EDO and FPM can be mixed between SIMMs, a given SIMM must contain only one type of DRAM. When
DRAM types are mixed each SIMM runs optimized for that particular type of DRAM.

PT-5IVL SYSTEM BOARD HARDWARE SETUP
4.2.2 L2 CACHE MEMORY INSTALLATION
The PT-5IVL system board will support one bank direct-mapped second level cache, and provides either 256KB
or 512KB cache memory, using synchronous pipeline-burst SRAMs. (Note that this system board does not
support asynchronous or burst SRAMs for the L2 cache memory) Both Write Back and Write Through cache
update policy are supported.
The second level cache is supported via a COAST (Cache-On-A-STick) module, there is no jumper needed for
end-user while using L2 cache memory, just insert the COAST module into the SRAM module slot (CN10),
then the cache memory size will be detected by system BIOS automatically.
Note : The COAST modules design must comply with Intel COAST (Cache-On-A-STick)
module specification revision 2.0 or later.
4.2.3 CONNECTORS
A connector is two or more pins that are used make connections to the system standard accessories (such as
power, mouse, printer,...etc.) The following is a list of connectors on board, as well as descriptions of each
individual connector.

size larger than 528MB:
NORMAL : For IDE hard disks size smaller than 528MB.
LBA : For IDE hard disks size larger than 528MB and up to 8.4GB (Giga Bytes) that use
Logic Block Addressing (LBA) mode.
Large : For IDE hard disks size larger than 528MB that do not use LBA mode.Large mode
is a new specifition which may not be fully supported by all operation systems.
Now it can only be used with the MS-DOS and is uncommon.
Note : Some OSes (like SCO-UNIX) must use "NORMAL" for installation.

Auto Configuration :
When "Enabled", this parameter automatically enters and locks some of the optimum values for the chipset and
CPU. Otherwise, this parameter allows the values of these parameters could be changed.
DRAM Timing :
When "Auto Configuration" is "Enabled", this parameter provides two suit of the optimum values for the chipset
and CPU, depends on the DRAMs' speed, you can select "70 ns" or "60 ns", but the first value maybe caused
your system more stable.

Power Management :
This setting controls the Power Management functions. "User Define" allows the values of all parameters could
be modified. "Min Saving" and "Max Saving" fixed the values of four parameters, including "Doze Mode",
"Standby Mode", "Suspend Mode" and "HDD Power Down".
"Disable" disabled all Power Management functions. Default is "User Define".

WARNING : The PNP/PCI CONFIGURATION in this screen are provided so that technical
professionals can modify the Resources Configuration to suit their requirement.
If you are not a technical engineer, do not use this program !
1st Available IRQ through 4th Available IRQ :
The System BIOS will assign these 4 avaiable IRQs to the found PCI devices. The settings are IRQ 3, 4, 5, 7, 9,
10, 11, 12, 14 and 15, include "NA".
PCI IRQ Actived By :
This option tells the system board chipset the IRQ signals input is Level or Edge trigger.
PCI IDE IRQ Map To : (for off-board PCI ICE cards)
PCI-AUTO : The BIOS will scan for PCI IDE devices and determine the location of the PCI IDE
device, then assign IRQ 14 for primary IDE INT#, and assign IRQ 15 for secondary
IDE INT#.
PCI-SLOT1 : For the specified slot, the BIOS will assign IRQ 14 for primary IDE INT#, and assign
to IRQ 15 for secondary IDE INT#.
