Setting Up Your System In this chapter you will learn about: how to unpack your main system how to assemble a knocked-down system how to upgrade your system Setting up a system is easy and takes only a short time. If your dealer has set up your system for you, you can skip this chapter.
2-1 Unpacking Your Main System lf you want to set up or upgrade your system, you will need to remove the cover of the unit. This is easily accomplished with the following tools: a small flat-blade screwdriver and a small Philips screwdriver. Be sure that the power to the system is switched off before you open the case.
2-2 Configuratlon The following will guide you through the physical installation of the mainboard. Restrictions Before installing the mainboard, we strongly recommend that you observe the restrictions mentioned below. • 27256 EPROM (BIOS) with 150ns access time • 1MbitX9 SIMM DRAM with 80ns access time •...
Board Layout The figure below will familiarize you with the layout of the Cache-386 33/40MHz mainboard. Figure 2-2: Motherboard Layout Chapter 2: Setting Up Your System...
lnstalling Processor The mainboard supports the 386-33/40 processor. You should insert the processor chip with the notch on into the corresponding notch on the PGA(Pin Grid Array) type processor socket if you have a PEM- 3335D/4035D mainboard, or the PQFP (Plastic Quad Flat Pack) type processor socket if you have a PEM-3335DS/4035DS mainboard.
Figure 2-3: Coprocessor Installation ROM lnstallation To install the ROM chips, refer to the illustration on page 4 for the location of the DIP sockets on the mainboard. ROM access time is 150ns. Chapter 2: Setting Up Your System...
Main Memory Configuration The mainboard has one kind of SIMM socket. The socket of the SIMM nodule is a 30-pin single-in-line module. Chip Insertion Remember that when inserting chips/RAM modules, you must make sure the notched or dotted end of the chip/RAM module is lined up with the notched end of the socket.
Total 32-bit Memory Switch Settings The location of the four-switch DIP SW1 can be. seen below. Each switch has an ON and OFF position (usually the ON position is labeled, the OFF position is not). SW1 should be set appropriately, based on the following illustration.
But if you use some other BlOSes with the switch settings (SW1-1, SW1-2, SW1-3) for total 32-bit memory larger than the physical DRAM installed, there will be an error message. This is caused by different methods of testing memory among BIOSes.
2-3 Jumper Options and Connectors After the switches are set correctly, other attachments and jumper option adjustments on the mainboard have to be made. See the illustration on page 4 for the location of the jumpers and connectors. The jumpers have been preset at the factory, but not necessarily for the system configuration you want.
Functions of Connectors and Jumpers A variety of connections can be made from the mainboard to a control panel on the front of your system. Following is a brief explanation of the various functions of the connectors that the mainboard supports: Reset Connector (Jumper J1) This connector connects the reset switch to your control panel.

Turbo Connector (Jumper J3) This connector switches the system between normal and turbo speeds. Note that Turbo and Normal modes can also be toggled with a software switch invoked from the keyboard as shown below: Speaker Connector (Jumper J4) This connector uses only two lines for the internal speaker. The pin assignments are listed below: Keyboard Lock/Power LED (Jumper J5) This connector attaches the keyswitch to your control panel and also...
Page 49
Coprocessor Option (Jumper J11) J11 is used to enable or disable the coprocessor. Keyboard Connector (Jumper 513) This connector is located at the back of your system unit. Any AT-com- patible keyboard with a 5-pin DIN connector may be used. The pin assignments for keyboard connector J13 are as follows: Power Supply Connector (Jumper 514) This connector is provided for the power supply.
Jumpers for Cache and Main Memory Configuration The cache configuration is 64KB cache (with eight 16Kbit x 4 cache SRAM chips and two 16Kbit x 4 tag SRAM chips). The figure on this page shows the jumper and switch settings for different onboard memory (DRAM) configurations.
2-4 Factory Default Settings Because of the large number of jumpers and options on the mainboard, it is best to start with the factory default settings and make experimen- tal modifications from that point. The following table shows the factory default settings.
2-5 Connection to Power Supply If you are installing the mainboard yourself, the final step is to attach the two six-pin cables from the power supply to the mainboard at connector J14. Be sure the four black wires of the power supply are located at the middle of the power connector.

Operating Your System In this chapter you will learn: a few MS-DOS functions the basics of the system setup and utility The software that your system will use falls into two categories. First there is the operating system, the language that tells the system what to do.
3-1 An Introduction to DOS DOS stands for Disk Operating System. This is used to control the operations of a computer and its peripheral com- ponents. DOS makes it easy for you to use applications and create and manage files on your computer. DOS also lets you use devices with the computer.
DOS Operations Following is a brief explanation of a few DOS functions. If you want a detailed explanation of all the DOS commands, refer to your DOS user manual. Starting MS-DOS lf you are using a hard disk with DOS already installed, the computer will “boot”...
Type the name you want to give the disk with a maximum of 11 characters, or press <Enter> if you don’t want a label, and show the following: Press <N> if you do have nothing else to be formatted. Backing In order not to lose your files through disk damage or accidental deletion it is important to back up all your files and diskettes regularly.
Deleting your Diskettes and Files You may want to erase diskettes or unnecessary files to make mom for other data. Erasing a diskette: To erase a whole directory of files, type the following at the drive prompt: A>del *.* <Enter> All the files in the open directory are now erased.
3-3 Hard Disk Drive Format A hard disk must be formatted before it can be read from or written to. To format a hard disk drive, you should carry out the following steps: step1— Preformatting The preformat utility is supplied by the system BIOS. You can press the <E >, key quickly just after the RAM test to enter the SETUP program.
Step 3 — Format The DOS command ‘Format” verifies the media and moves the system file onto the hard disk drive. The command should be keyed in as: A> FORMAT C:/S If you have two partitions, you should format D from the DOS prompt. The command should be keyed in as: A>...
3-4 Helpful Hints The following may save you some time or help you as you use your computer. Make copies of your diskettes regularly. To make sure that a command works, you should: — Check your typing (make sure you don’t confuse \ with /). —...

Floppy Disk Drive There are two general types of problems with floppy disk drives. First, the LED on the floppy disk drive may not turn on when you try to read information from an inserted disk. Second, the read head on the inside of the drive may not be moving properly.
Page 90
Use the diagnostic software on your computer. Try to find out the conditions under which the malfunction occurs. Try also to isolate where the problem is occurring. Is it with a certain software program or with your hardware? If the problem is with software, you should probably talk to your software dealer.
5-2 System Error Messages Basically there are three levels of system error messages that you might see displayed on your computer. These are related to the software you use. The following are the ones most commonly en- countered. Software error messages are a result of: the application becomes stuck and the cursor will Software lockup: not move.
5-3 Examples of System Error Messages System crash The cursor cannot be moved and does not respond to the keyboard. This could indicate a software crash. Mark where you are in your document. Reboot your system and reload your software. Scroll the cursor to where you last saved your data.
