Static Electric Discharge Precautions
Static electric discharge can deliver a high-voltage shock to the mainboard sufficient to damage or destroy components on the board. Because of this, it is important to observe precautions when you handle the mainboard and any devices you install on it, including the CPU, memory modules and expansion cards.
There are several simple precautions you can take:
•Use an anti-static wrist strap, which can be purchased inexpensively from most computer stores. Connect the strap lead to a grounded metallic object and put on the strap before touching any components.
•Put components on an anti-static pad or keep them in their anti-static packaging until you install them.
•If you don’ t have a wrist strap or pad, make sure to touch a metallic object such as the system case to ground yourself before handling any components.

Clock Generator Chip
Important Note
The PR5 uses one of several clock generator chips. The DS DIP switch block settings vary depending on which chip is installed. To determine the correct settings you need to know which clock chip is installed. The position of the chip on the mainboard is noted above. The chip part information is printed on the top of the chip. The options are:
ICS :
I C S 9 1 5 9 - 1 4
PhaseLink:
PLL52C59 -14T or PLL52C61-01 or PLL52C61-21
These clock generator chips support a “Normal”and a “Turbo” mode. Normal mode is the CPU manufacturer’s rated clock speed. Turbo mode is an overclock mode that increases the CPU’s clock speed by 2.5% over the Normal rating. For maximum stability and compatibility you should use the Normal mode for the CPU you are installing.

Impo rtant N ote: 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.
•If bank DIMM2 has a 2-sided module installed, you can not use the SIMM1/ 2 sockets.
Double-sided modules are modules with memory chips mounted on both sides.
DRAM Installation
The PR5 has numerous possible system memory configurations using the four 72-pin SIMM sockets and the two 168-pin DIMM sockets. The SIMM sockets work in banks of two to provide a 64-bit data path. SIMM1/SIMM2 are one bank, SIMM3/SIMM4 are another. The DIMM sockets are each a bank, for a total of four banks. Please note the following.
•Installed memory is auto-detected by the BIOS
•Minimum installation 2 SIMMs or 1 DIMM module for a 64-bit data path
•Fast Page (FP), EDO and SDRAM are all supported, SDRAM only in DIMM modules
•SIMMs: single or double-sided modules of 4MB and up supported
•DIMMs: single or double-sided modules of 8MB and up supported
•DIMM sockets support both 5-volt (FP or EDO) and 3.3-volt (Unbuffered) DRAM; voltage for both sockets is set by jumper JP11 (see next page)
•Pairs of SIMMs must be the same memory type, size and speed but the type and size of a second pair can be different
•Memory Banks: SIMM1 & SIMM2 SIMM3 & SIMM4 D I M M 1
D I M M 2
•Bank sequence doesn’ t matter, use any combination as long as other requirements are followed
•DRAM speed must be at least 70ns, can be faster
•Parity checking is not supported
•Maximum 128MB supported
There are numerous allowable memory configurations. Since bank sequence is not important, as long as you use SIMMs in pairs you can use any combination of banks.
However, for maximum performance it best to use the same type of DRAM in all banks installed. SDRAM provides higher performance than EDO DRAM and EDO is faster than Fast Page Mode DRAM.
!
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.
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.

Enclosure Features Connectors
Not every pin in the connector block for system case features is used. Which features are used depends on the specific case design. If your case does not have a Keyboard Lock, you can still connect a Power LED lead to Pin 20 and either Pin 16 or 18. Refer to the chart at right for the pin assignments.

P R 5 H a r d w a r e C o n f i g u r a t i o n
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. Since you are more likely to need the upgrade options, they come first. The section is organized as follows
•CPU Options & Installation
•System Memory Configuration
•Level 2 Cache Options
•Onboard Connectors
•DIP Switch and Jumper Summary
The information in this section augments the Configuration Quick Reference. So these sections provide additional detail, with some review.
CPU Options & Installation
The PR5 supports a wide assortment of CPU chips from various manufacturers. It is also designed to provide as much upgradability as current information on future CPUs allows. We must note, however, that only the CPUs listed in the manual have been certified to work with the PR5.
Related Terminology
To make it easier to understand the information this section you may want to review the following terms.
Clock
You’ ll see this term used in several ways. Here it doesn’ t refer to keeping time and is not the clock that keeps the date and time setting for the system. The mainboard relies on the system clock to provide digital timing pulses at a constant frequency. The signal the clock generates synchronizes all operations on the board. This “clock frequency” , or the number of signals per second is what we usually think of as the clock “speed” of the system.
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. The internal speed is set by the Clock Multiplier Factor. For example, the Intel Pentium P90, P120 and P150 CPUs all have the same external clock, 60MHz, but have different clock factors.
Internal Clock
The Internal Clock is a multiple of the external clock and is the speed used to list the processor’ s operating speed. The internal speed is set by the Clock Multiplier Factor. For example, the Intel Pentium P150 CPU has a 150MHz internal clock speed, a 2.5 multiple of the 60MHz external clock.
Clock Multiplier Factor
The clock multiplier factor is the factor by which the external clock is multiplied to set the CPU’ s internal clock speed. The PR5 has four options: 1.5, 2, 2.5, 3. For example, the Pentium P166 requires a 66MHz external clock and a 2.5 clock multiplier factor to establish its 166MHz internal clock speed. Note: The full clock frequencies are rounded off for convenience when listed, so while 66 x 2.5 = 165, the actual clock speed is 166MHz.
ISA Bus Clock
This is the clock speed of the ISA expansion bus and may also be referred to as the ISA speed, AT Bus Clock or AT clock. The original specification was 8MHz. The slower speed ensures compatibility with all ISA expansion cards. Newer ISA expansion cards may be able to operate at faster speeds, which provide increased performance. The PR5 can be set for slower or faster ISA Bus clock speeds. The slower speed ensures maximum compatibility.
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. For example, the Cyrix 6x86 P166+ has a clock speed of 133MHz, but performs at an effective speed equal to or greater than 166MHz. The P–rating indicates the effective, rather than the actual clock speed of the CPU.
CPU Settings
To configure the PR5 for the CPU you will install you have to set the switches on the two CPU configuration DIP switch blocks DS and VC. The procedure is as follows:
|
1. |
Set the Clock Multiplier Factor using switches DS1 |
|
and DS2 on the DS DIP switch block. |
|
|
|
|
|
2. |
Set the External Clock configuration using switches |
|
|
DS3, DS4 and DS7 on the DS DIP switch block. |
|
3. |
Set the ISA Bus Clock configuration using switch |
|
|
DS5 on the DS DIP switch block. |
|
4. |
Make sure DS6 on the DS DIP switch block is OFF. |
|
|
This controls DRAM refresh and is reserved for use |
|
|
with future CPUs. The default setting is OFF. |
|
5. |
Make sure DS8 on the DS DIP switch block is OFF. |
|
|
This is reserved for use with future CPUs. The de- |
|
|
fault setting is OFF. |
|
6. |
Set the Vcore/Vio configuration using the VC DIP |
|
|
switch block. |
|
7. |
Make sure jumper JP10 is set to the default “Open” |
|
|
setting (no jumper cap connecting the two pins). |
In order to give you more CPU configuration options we have included Turbo settings which increase system performance somewhat as well as the standard CPU configurations which maintain maximum stability and compatibility. The Turbo settings are labeled as such and all other settings are standard. The charts on the following pages show the settings for various CPUs.
