P/I-AP55T User's Manual Using Your Mainboard In addition to the operating instructions in your system manual, there are a few additional things specific to the mainboard you will need to know. These have to do with the hardware settings on the mainboard and the system configuration record. Hardware Settings There are a number of hardware settings on the board. They specify configuration options for various features. The settings are made using something called a 'jumper'.
Feature Guide Setting options for most jumpers are printed on the board in a stylized bird's-eye view, with which pins to connect for each setting marked by a bar connecting two pins. For example, if a jumper has three pins, connecting, or 'shorting', the first and second pins creates one setting and shorting the second and third pins creates another. The same type of diagrams are used in this manual.
P/I-AP55T User’s Manual The System Configuration Record All personal computers use a BIOS (Basic Input Output System) as the basic software that tells the computer how to function. In or der for the BIOS to function, there has to be a record of the computer's hardware and configuration settings for it to refer to. This record is created by using a software program permanently stored in the BIOS ROM chip on the mainboard. The program is called the BIOS Setup Utility.
Feature Guide System IRQs Later in the manual you'll see something called an "IRQ" men tioned several times. If you're not familiar with these, this is a short explanation of what they are and why you may need to know about them if you upgrade your system. An IRQ, or interrupt request, is the process whereby an input or output device tells the CPU to temporarily interrupt whatever it is doing and immediately process something from the source of the interrupt.
P/I-AP55T User's Manual BIOS-Supported Enhanced IDE Features The BIOS has several feature enhancements for IDE hard disk drives and support for other ГОЕ devices. ,The original IDE implementation was limited to two hard disk drives with relatively slower data transfer rates.
Feature Guide Large IDE Hard Disks For ГОЕ hard disk drives, the BIOS provides three modes to sup port both normal IDE hard disks and also drives larger than 528MB: Normal - for IDE drives smaller than 528MB Large - for drives larger than 528MB that do not use LBA. These can only be used with the MS-DOS operating system. LBA - for drives larger than 528MB and up to 8.4 GB (GigaBytes) that use Logic Block Addressing mode. Other IDE Devices Enhanced IDE allows the use of IDE devices other than hard disks.
P/I-AP55T User’s Manual Dual IDE Channel Support With the onboard ГОЕ controller you can connect up to four ГОЕ peripheral devices to your system. With Enhanced ГОЕ you can con nect two devices to each connector. All devices are categorized the saíne way IDE hard disks have been in the past, with one device set as the "Master'' device and the second as the "Slave" device. These two charmels are called the "Primary" and the "Secondary" channel. The Primary channel uses IRQ14, the Secondary, IRQ15.
Feature Guide Onboard VGA & Audio Features The onboard VGA display and audio features come with exten sive software drivers and utilities. The other manual in the mainboard package explains how to install and use the software for these fea tures. There is information on the hardware setup for these features in Chapter 4 of this manual. VGA Hardware & Software The onboard VGA display is capable of displaying multiple reso lutions and color depths (numbers of colors) at a variety of refresh rates.
P/I-AP55T User's Manual SCSI BIOS Firmware & The Optional SC-200 Controller Card This mainboard has onboard NCR SCSI firmware recorded in the BIOS flash ROM chip that supports the NCR 53C810 PCI Fast SCSI2 controller. There is an optional SCSI controller card, the SC-200 that uses this firmware. The NCR SCSI controller is a full 32-bit PCI DMA bus master and supports the ASPI and CAM standards. You can connect a chain of up to seven devices to the SCSI inter face.
This section explains how to install options on your mainboard. It covers the most likely and technically accessible upgrades you might want to do, including installing expansion cards, adding sys tem or video memory, installing ГОЕ devices and upgrading the CPU. Installing upgrades will either improve the performance of your computer, or add some additional capabilities to it. You can install upgrades yourself, or have your dealer or a qualified computer ser vice technician do it for you.
P/I-AP55T User’s Manual Before you start, always make sure the computer is turned off. You should also make sure to observe standard static electricity dis charge precautions. You can damage your expansion card, the mainboard, or both by not being careful about this. ' The basic procedure for installing expansion cards is the same for both ISA and PCI cards. The basic procedure is as follows: 1. Open the system case to gain access to the expansion slots. 2.
upgrade Guide Assigning System IRQs for Expansion Cards Cards for both the ISA and PCI buses may need to use IRQs. You must configure any IRQ assignments so that the system can know which IRQ is assigned to which card. IRQs must be assigned correctly or the mainboard will not work properly. As mentioned in Chapter 1, there are 16 IRQs. Some of them are already in use by standard parts of the system such as the keyboard or mouse. IRQs 5,10 and 11 are not used by the mainboard and are available.
P/I-AP55T User's Manual Installing Expansion Cards That Use An IRQ Example PCI installation procedure: 1. Choose a slot to usee.g. PCI Slot 1 - fixed INT A# 2. Make sure Slot 1 is setto the "Auto" setting 3. Configure the card you will install in PCI Slot 1 to use INT A and install it Example ISA installation procedure: 1. If it is a Legacy card, select the ISA IRQ it will use. If PNP card, skip this. e.g. IRQ 5 2. If it is a Legacy card, set IRQ 5 as used by ISA in PCI and PNP Setup, or use ICU.
upgrade Guide Upgrading System Memory This section explains how to install system memory. There are instructions on how to configure and install memory and an expla nation of the technical specifications required. System DRAM is the main source of data for the CPU. Data re mains stored in DRAM as long as the system is turned on, and is lost when you turn it off. The Level 2 cache memory is Static RAM (SRAM), which is faster than DRAM memory. When the CPU looks for data, it first searches the cache.
P/I-AP55T User's Manual Configuring System Memory If you want to add system memory, you must use the configura tion options and specifications shown in this section. Memory Combinations You can configure the system memory in a variety of ways, us ing different combinations of SIMM modules. Using the 4 SIMM sockets there are many configuration options. The following chart shows the supported combinations. The only restrictions are: • You must use 2 sockets at a time, in sequence, i.e.

P/I-AP55T User’s Manual Installing SIMMs To install SIMMs follow these instructions: 1. The modules will only insert in a socket in one orientation. An - orientation cut-out will prevent you from inserting them the wrong way. See the figures at right. 2. Press the module edge connector into the socket at a moder ate angle to the board. See the figures below. 3.
Cut-out SIMMs have a cut-out at one end that matches an extension on one of the vertical posts of e a c h socket. Put orientation cut-out at this end. SIMM# 4 3 2 1 V T £ E Install modules starting with the SIMM1 socket on the righthand side. Modules may have chips on one or both sides.
P/I-AP55T User's Manual Upgrading Video DRAM Memory The mainboard comes with 1MB of video display DRAM mounted on it. In addition, there are two expansion sockets that al low you to expand the video display memory to 2MB. To expand the video display memory, you must install two 512KB DRAM chips in the expansion sockets. To install the chips, observe static discharge precautions and do as follows: 1. Open your system case and find the video display memory ex pansion sockets, located near the monitor port.
upgrade Guide Installing IDE Hard Disks This section explains how to install IDE hard disk drives or other devices. You can connect up to four ГОЕ devices to the onboard con nectors. This section explains the information specific to this mainboard, not the basic procedure for how to install a hard disk in your system. Your system manual should have instructions specific to installing devices in your case.
P/I-AP55T User’s Manual Installing Additional IDE Devices If you have space in your system case, you can install another ГОЕ hard disk or other IDE device using the procedure on the previous page. Install the drive in an empty drive bay and cormect the drive to the unused middle connector of the ГОЕ ribbon cable. Note that a second IDE device on a channel must be set to function as a "slave" device, because the first ГОЕ device functions as the "master" device.
upgrade Guide Updating the Flash BIOS This mainboard has two BIOS ROM chip options. It can use ei ther of two programmable 'flash' EPROM chips, 5-volt or 12-volt, either of which you can update when BIOS upgrades are available. Jumper JP9 enables programming for the BIOS ROM chip. There are two settings. The default setting, which shorts pins 1&2, is for Write-Protect/Normal Read. The other setting, which shorts pms 2&3, is for Enable Programming.

P/I-AP55T User’s Manual I/O Port Connectors Pini is the upper left-hand pin on each connector Floppy Disk Drive cable connector IDE Hard Disk Drive cable connectors. Primary IDE (Middle) Secondary IDE (Right) W hen you connect a ribbon cable to any of these I/O connectors, you must orient the cable connector so that the Pin 1 edge of the cable is at the Pin 1 end of the on-board connector.
Technical Summary Connecting A Power Supply The system power supply connector is for a 5-volt power supply. To connect the leads from the power supply, you should first make sure the power supply is unplugged. Most power supplies have two leads. Each lead has six wires, two of which are black. Orient the connectors so the black wires are in the middle. Align the plastic guide pins on lead to their receptacles on the connector. You may need to hold the lead at an angle to line it up.

Technical Summary The PCI-SC200 SCSI Interface Card Your mainboard may have come with an optional SCSI (Small Computer System Interface) controller card, the PCI-SC200. The card is also available separately. This card works with the SCSI BIOS on the mainboard. Together, they provide a complete PCI Fast SCSI-2 in terface. With the card installed in your system you can connect SCSI devices installed in your system case to the internal cormector on the card.
P/I-AP55T User’s Manual Setting Up the PCI-SC200 There are two jumper settings you may need to make on the card to set it up. One setting assigns the PCI INT interrupt the other sets the card's termination. Setting the INT Assignment As explained in Chapter 2, any PCI card you install must use PCI INT A. On the PCI-SC200, you assign the INT by setting jumper JPl or JP2. The default setting for the card already is INT A, so you do not need to change the setting to use the SC-200 with this mainboard.
Technical Summary Terminator Settings SCSI devices are cormected together in a "chain" by cables. In ternal devices connect to the PCI-SC200 with a fifty-pin flat ribbon cable. External devices connect to the external port with a SCSI-2 cable. If there is more than one internal or external device, additional devices are connected with cables to form a "daisy chain". The SCSI chain must be "terminated" at both ends, or the devices in the chain will not work properly.
P/I-AP55T User's Manual Example 1: Only internal or only external devices connected Internal SCSI Cable SCSI Device 1 (Termination Disabled) SCSI Device 2 End Device (Termination Enabled) Note: SCSI controller card ID# is "7".
Technical Summary SCSI ID Numbers All SCSI devices, including the PCI-SC200 interface card must have a SCSI identification number that is not in use by any other SCSI device. There are eight possible ID numbers, 0 through 7. The PCISC200 has a fixed SCSI ID of 7. You can connect up to seven SCSI devices to the interface card. You must set a SCSI ID number for each device. SCSI devices vary in how they set the ID number. Some use jumpers, others have some kind of selector switch.
