DRAM Installation ! Important Note: Double-sided Modules There is an important limitation in using double-sided SIMM or DIMM modules. Double-sided modules in one bank prevents the use of a corresponding bank of the other type of module. For example: • If bank SIMM1/2 has 2-sided modules installed, you can not use the DIMM2 socket. • If bank SIMM3/4 has 2-sided modules installed, you can not use the DIMM1 socket. • If bank DIMM1 has a 2-sided module installed, you can not use the SIMM3/ 4 sockets.
DIMM Voltage Settings ! The DIMM sockets support both 5-volt and 3.3-volt unbuffered DRAM. The voltage setting for both DIMM sockets is controlled by jumper JP11. The socket voltage setting must match the voltage of the DRAM on any DIMM modules you install. The jumper settings are shown below. DIMM Voltage Settings Jumper JP11 sets the voltage supplied to the DIMM sockets. FP & EDO modules use the 5-Volt setting. Default Setting : 3-Volt.
O n b o a rd C o n n e c to rs The PR5 has onboard connector headers for the disk controllers, I/O ports, system enclosure connections and several other features. Pin 1 locations are noted for cable orientation. Drive Controller & I/O Port Connectors The PR5 has floppy disk drive, Enhanced IDE controller, serial, parallel and USB port connector headers onboard. Drive Controller Connectors The Floppy Disk Drive Controller connector is a 34-pin header.

If this is the case, you must connect the power supply leads so that the black wires are grouped together in the middle.
PR5 Hardware Configuration This section describes how to configure the PR5 mainboard hardware in more detail than the Configuration Quick Reference at the beginning of this section. It is intended for users who are less familiar with computer hardware. If your PR5 is already installed in a system you will not need much of this information unless you need to reconfigure your system. This section covers all the standard features on the board plus the upgrade options.
In Pentium-based designs there is more than one clock speed. The mainboard components run at one speed and the CPU will run at the same speed in its external activity, but will run at some multiple of that speed internally. External Clock The External Clock, also sometimes referred to as the external CPU clock or bus clock, is the CPU’ s input clock. The CPU will interface with other components at this speed and its internal clock speed is a multiple of this external speed.
CPU Voltage – Vcore & Vio The CPU input voltage has two components, Vcore and Vio. Vcore provides the power for internal processing and Vio for the external interface. The two settings are linked, so the VC DIP settings cover both of them. P–Rating The “ P–Rating” is a categorization used to rate the performance of some Pentium-compatible CPUs. The rating system was created because some CPUs perform at a higher effective speed than their internal clock speed indicates.

System Memory Configuration The PR5 is designed to provide the broadest possible memory configuration options. The design includes four sockets for the currently most common form factor, 72pin SIMM modules and also has two sockets for the future standard, 168-pin DIMM modules. The DRAM on the SIMM modules can be either Fast Page mode or EDO DRAM. DIMM modules can use these and can also use the newer SDRAM (Synchronous DRAM). You can install a combined total 128MB of all memory types on the PR5 mainboard.
The PR5 has numerous possible system memory configurations using the four 72-pin SIMM sockets and the two 168-pin DIMM sockets.
PR5 Memory Configuration Examples SIMM1/2 SIMM Banks You can install memory in bank SIMM1/2 only, SIMM2/3 only or both banks. The bank order doesn’t matter. You must install two modules of the same size, type and speed in a bank. SIMM3/4 Total 4MB/4MB 8MB/8MB 8MB 16MB 16MB/16MB 32MB 32MB/32MB 64MB 64MB/64MB 128MB You can mix different sizes between banks in any combination as long as the total doesn’t exceed 128MB. You can even install different DRAM types in between banks (FP or EDO).
DIMM Voltage Settings The DIMM sockets support both 5-volt and 3.3-volt unbuffered DRAM. The voltage setting for both DIMM sockets is controlled by jumper JP11. The socket voltage setting must match the voltage of the DRAM on any DIMM modules you install. The jumper settings are shown below. JP11: DIMM Voltage Pins 1-2 Pins 2-3 ! DIMM Voltage Settings Jumper JP11 sets the voltage supplied to the DIMM sockets. Default Setting : 3-Volt.
Installing Memory Modules Installing memory modules is easy, but there are a few important precautions you should take whether you are installing SIMM or DIMM modules. The most important is to guard against damage to the modules from static discharge. A strong enough discharge can make a module unusable and ruin your investment. If you’ re not familiar with static precautions, you may want to review the information on this in Section 1.
Installing DIMMs To install any kind of DIMM module do as follows: 1. Orient the short section of the edge connector so that it is at the upper end of the socket. 2. Insert the module edge into the socket at a 90° angle so that the contacts insert as far as they will go. 3. The retaining clamps at each end rotate upward to secure the module in the socket. The figure below shows where the orientation features are located.
Level 2 Cache Options The Level 2 cache on the PR5 greatly speeds up system operation. There will be at least 256KB of very fast Pipeline Burst Static RAM (SRAM) cache memory mounted either on the mainboard or on a cache module that installs in the cache socket. You can upgrade the Level 2 cache to a maximum of 512KB regardless of whether the memory is on the board or on a module.
O n b o a rd C o n n e c to rs There are several connectors for various features on the mainboard. If your PR5 is already installed in a system, you can skip this section. The PR5 has onboard connectors for the floppy and hard disk controllers, I/O ports, connections from your system case and several other features. Their locations are shown in the Configuration Quick Reference, so they are not repeated here. This section explains what the connectors are and how they work.
The two Enhanced IDE Controller connectors are for the two IDE channels Channel 1 and Channel 2. Channel 1 is the Primary channel and is divided in two as the Primary Master and Primary Slave. Channel 2 is the Secondary channel and is organized the same way. There are ribbon cables for each channel. Enhanced IDE allows a total of four devices, two attached to each IDE channel. The first device in each channel attaches to the end of the cable.
System Enclosure Connectors The system enclosure is your system case. There are usually several features built-in to the case that connect to the mainboard. The PR5 has connections for a number of these in a connector block which includes connectors for a Reset button, Suspend switch, Turbo LED, Speaker and Keyboard lock. Your system case may or may not have all of these features. The location of the connector block and the pin assignments are shown in the Configuration Quick Reference.

IDE Activity LED Connector The IDE activity LED connector is a 4-pin connector which will accept either a 2-pin or 4-pin IDE LED activity light connector. This light comes on when an IDE device in your system is being accessed. If you are connecting a lead from an LED activity light on your case, make sure you identify which wire is the positive wire and orient the lead’ s connector so that the positive wire connects to the positive pin on the onboard connector.
DIP Switch & Jumper Summary This section lists the function of all the DIP switches and jumpers on the board for your reference.
Other Jumper Functions There are two other jumpers on the PR5 which have not been mentioned yet. One is JP3 (Clear CMOS Memory) and the other is JP8 (Flash ROM Type). JP3: Clear CMOS Memory The onboard CMOS memory is where the system configuration information set by the BIOS Setup program is stored. If you make entries in the Setup program that will prevent the computer from booting up or you set a password and then forget it, you will not be able to use the computer.
JP8: Flash ROM Type This jumper is set at the factory for the type of Flash ROM chip installed. You should not change the setting and it is shown here for reference only. This jumper may be replaced by hardwiring directly onboard on some boards. There are two types of Flash ROM chip, 5-Volt and 12Volt. The chip type has no functional effect. The settings and location are shown below. Jumper JP8 Location JP8: Flash Chip Type This jumper is factory set for the type of Flash Memory Chip installed.

IDE Installation Guide This section is a guide to installing IDE devices in your computer system. It covers installing devices you connect to the mainboard’ s onboard Enhanced IDE controller. The main hard disk drive used in most systems is an IDE device. In addition to this, however, you may want to install more hard disks, a CD-ROM drive or combination of these. The onboard controller supports up to four devices.
Installing IDE Devices The Enhanced IDE controller on the PR5 supports four devices in two channels, IDE1 and IDE2, which are also referred to as the Primary and Secondary channels. Each channel supports two devices, the first device is called the Master and the second device the Slave. IDE devices must be configured to operate as one or the other. To find out how to configure the drive hardware you should check the documentation that comes with the drive.
Example 1: One Hard Disk To install this configuration: 1. Make sure the drive is configured as a master drive. Most drives are set this way at the factory. 2. Connect the Master end of the IDE ribbon cable to the drive aligning the Pin 1 positions and install it in the system case. 3. Plug the other end of the IDE cable onto the IDE1 connector on the mainboard with the Pin 1 positions aligned. 4.
Example 3: Two Hard Disks To install this configuration: 1. Make sure one drive is configured as a Master drive and the other as a Slave drive. Most drives are set to Master at the factory. Alternate Installation You can also install these as follows: Hard Disk 1: Primary Master Set drive as Master. Attach to end of 1st IDE cable, attach other end to PR5 IDE1 connector. Hard Disk 2: Secondary Master Set drive as Master. Attach to end of 2nd IDE cable, attach other end to PR5 IDE2 connector. 2.
7. Use the BIOS CMOS Setup Utility to enter the drive parameters for the Primary Master and Primary Slave as described in the Standard CMOS Setup section of Section 3. The CD-ROM drive does not require this. 8. Format the hard disks as required by the operating system you will use. The Primary master is the boot (start-up) drive. Example 5: Three Hard Disks To install this configuration: Alternate Installation You can also install these as follows: Hard Disk 1: Primary Master Set drive as Master.
Example 6: Three Hard Disks & One CD-ROM Drive To install this configuration: 1. Make sure two hard disks are configured as Master drives and the other as a Slave drive. Most drives are set to Master at the factory. 2. Connect the Master end of one IDE ribbon cable to one of the Master drives aligning the Pin 1 positions and install it in the system case. 3. Install the Slave drive in the system case and connect the IDE ribbon cable’ s Slave connector to it, aligning the Pin 1 positions. 4.
BIOS Setup W hen you install hard disk drives you must enter their parameters in the Standard CMOS Setup section of the BIOS CMOS Setup Utility as explained in Section 3. For new drives you should use the IDE HDD Auto Detection feature to automatically determine the drive parameters and enter them in the required locations. If you install a drive that has already been in use, you can use the auto-detection feature with two considerations.
Technical Support In order to help solve any problems that might arise in the course of using your PR5 mainboard we have included a few troubleshooting guidelines and some pointers about collecting information on your system to aid the technical support process. You should consult your vendor for instructions on how to obtain technical support. Troubleshooting Guidelines Here are some basic troubleshooting guidelines that may help you identify more specifically the cause of a hardware problem.
You can then use a text editor to deactivate the sound card driver in the CONFIG.SYS file. To do this, you must find the line in the CONFIG.SYS file that loads the driver and type REM and a space at the beginning of that line. For example, using an example CONFIG.SYS file: DEVICE=C:\DOS\HIMEM.SYS DEVICE=C:\DOS\EMM386.EXE HIGHSCAN DOS=HIGH,U MB FILES=40 BUFFERS=36 REM DEVICEHIGH=C:\PLUGPLAY\DW CFGMG.
9. System DRAM Specifications: The manufacturer, type, size and speed of the installed DRAM. For example: Panasonic, SIMM-FP DRAM, 4MB-06 or NpNX, SIMMEDO DRAM, 8MB-06 or SEC, DIMM-S DRAM, 8MB-G12 1 0 . Coast Cache Module Specifications: The manufacturer, size and product number of the installed COAST cache module. For example: Winbond, 256KB, W 2 5P01 0AF -8 1 1 .
