`

`
`Hardware Installation Step by Step
`
`The installation of your Nx586 system board consists of 6 basic steps (your installation may vary
`depending on your system configuration):
`
`Step 1.
`Step 2.
`Step 3.
`Step 4.
`Step 5.
`Step 6.
`
`Configure the system board.
`Install the system board into your computer chassis.
`Install the DRAM modules.
`Install any internal PCI/ISA peripherals.
`Connect the monitor, keyboard, and other external peripherals.
`Run the WINBIOS Setup program to configure your system board's memory, hard
`drive and floppy drive parameters.
`
`Step 1. Configuring the System Board
`
`The Nx586 system board options are configured through both software/WINBIOS and hardware
`jumpers. The software/WINBIOS configuration settings are discussed in the Software Configuration
`section of this manual and the Technical Reference section of this manual lists all of the jumper
`settings for the Nx586 system board. We do not recommend changing ANY jumper settings unless
`the user is an experienced installer -- misuse of jumper settings can result in system board failure
`and/or loss of warranty. The factory default configuration for the onboard peripherals is:
`
`Onboard serial ports:
`Onboard parallel port:
`Onboard floppy controller:
`Onboard IDE controller:
`
`Enabled as COM1 and COM2
`Enabled as LPT1
`Enabled
`Enabled
`
`Please refer to the appropriate section of this manual if you need to change any of these settings.

`

`
`Step 2. Installing the System Board
`
`CAUTION!
`Make sure to observe precautions for handling static
`sensitive devices. Static electricity can harm
`components on your Nx586 system board and cause
`system failure.
`
`The Nx586 system board is designed to fit into most standard AT/Baby AT enclosures. Follow the
`instructions for your particular chassis in order to install the Nx586 system board. Make sure your
`chassis power supply can generate adequate power for your system board and peripherals. For safety
`purposes, NexGen recommends using only chassis' that employ UL, CSA or TUV certified power
`supplies.
`
`WARNING:
`The Nx586 processor requires adequate air flow to
`dissipate the heat generated by the processor. Make
`sure that the processor fan is not obstructed and is
`operational. If the fan is not working, return the board to
`your dealer for an exchange.

`
`

`
`Step 3. Installing DRAM Modules
`
`The Nx586 system board accommodates six 72-pin, 32-bit or 36-bit DRAM SIMM modules. When
`installing memory, the DRAM speed for P90 and P100 systems must be 70ns or faster, and must
`support fast-page mode. The six SIMM slots are labeled in pairs as Bank A, Bank B and Bank C.
`The banks may be populated in any order, (Bank C then Bank A then Bank B etc..) but both SIMMs
`within a bank must be installed at the same time with the same density (1M, 2M, 4M ...) of DRAM
`module. Any of the following single density SIMMs, (1M, 4M or 16M) or double density (2M, 8M or
`32M) SIMM modules may be used. Table 1-1 shows a short list of the possible memory
`configurations.

`
`Step 4. PCI/ISA Bus Adapter Installation Procedure
`
`To install a PCI or ISA-Bus adapter card:
`
`1. Locate a free PCI or ISA Bus slot on the system board, either a PCI or ISA slot whichever is
`appropriate for the card to be installed.
`
`2. Remove the appropriate expansion slot cover plate from the chassis.
`
`3. Line up the adapter along the slot to be used and insert the gold-edged connectors into the
`connector on the motherboard completely. Make sure that the adapter is well seated in the
`slot. Secure the adapter to the chassis with a slot cover screw.
`
`4. The system should automatically recognize the added adapter. If you have added a video
`adapter and wish to use the extended video modes, you may have to install additional drivers
`corresponding to the programs and environments used.
`
`Step 5. Connecting External Peripherals
`
`Connect your monitor, keyboard, mouse, AC power cord, and other external devices to your chassis
`before powering on the system.
`
`Step 6. Running WINBIOS Setup
`
`Once the motherboard has been mounted in the case and all of the peripherals connected, the final
`step is to run the WINBIOS setup program. When the system is turned on for the first time, the
`WINBIOS will notice the addition of DRAM memory and other peripherals and prompt you to enter the
`setup utility. The next section of this manual describes the use of the AMI WINBIOS Setup utility in
`configuring your system. After running Setup, you can proceed with installation of system and
`application software.

`
`AMI WINBIOS Setup
`
`Introduction
`
`The WINBIOS setup is a program in the Flash ROM (permanent memory) of your system board that
`configures the DRAM, date and time, the type and number of hard disks connected, and virtually all of
`the main system level components. The WINBIOS Setup values may have already been set prior to
`shipment.
`
`A record of the system parameters (such as amount of memory, types of disk drives, video display,
`numeric coprocessor, and other peripherals) is stored in a special area of memory called CMOS
`RAM. When the computer is turned off, a backup battery provides power to the CMOS RAM, thereby
`retaining your system configuration. The backup battery contained on this motherboard is rated for a
`10 year average life.
`
`Each time the system is turned on it is configured with the values stored in the CMOS RAM, unless
`the CMOS RAM was corrupted. If for some reason, the CMOS RAM is corrupted, the system is
`configured with the default values stored in the Flash ROM. There are two sets of WINBIOS values
`stored in the Flash ROM: the WINBIOS Setup default values and the Power-On default values.
`
` Note: Your system may have been pre-configured prior to
` only necessary to execute the configuration program if:
`
`shipment. It is
`
`You have changed the hardware configuration (i.e.: added
`*
` memory, added or removed drives, etc.).
`
`The system itself has detected an error while booting up and
`*
` requires you to reconfigure CMOS RAM.
`
` Users are not encouraged to run this setup program unless they are familiar with it.
`Improper use of this setup program can result in system failure.
`

`
`

`
`Running the WINBIOS Setup
`
`When the system power is turned on, the computer performs a series of device initializations and
`diagnostic tests. During this process, the system will allow you to interrupt the process and run Setup
`by pressing the <Del> key. When the Power-On-Self-Test (POST) has completed, the following
`message appears:
`
`Press the <Del> key to enter the Setup program.
`
`Once inside the Setup program, either a mouse or the keyboard can be used to maneuver and modify
`the setup parameters. The table below describes special keys used to perform certain functions
`within the Setup program.

`
`The WINBIOS will also recognize most PS/2, serial and in-port style mice. The mouse click functions
`are:
`
`• single click to change or select items
`
`• double click to perform an operation in the current field
`
`• click on the “close box” in the upper left corner of a window to close the window or exit from
`Setup
`

`
`

`
`Exiting the Setup Program
`
`When finished making changes within Setup press the <Esc> key until the following menu shown in
`figure 2 appears. At this point, you are presented with the three choices described below.
`
`Figure 2. Exit Setup Menu
`
`Save Changes and Exit
`This option is used to save the changes made during this session in the Setup program then continue
`the boot process. After pressing <Enter> with this option highlighted all settings that were modified
`are stored in CMOS RAM then a CMOS RAM checksum is calculated and written to CMOS RAM.
`Control is then passed to the ROM WINBIOS and the WINBIOS either reboots the system, (if any new
`setting changed the memory map) or continues the booting process.
`
`Do Not Save Changes and Exit
`This option passes control to the WINBIOS without writing any changes made to the CMOS RAM.
`Press <Enter> with this option highlighted to continue the boot process without saving any altered
`system parameters.
`
`Continue
`Press <Enter> with this option highlighted to return to the main menu of the Setup program.

`
`

`
`Standard Setup
`
`This menu permits the user to configure and set system components such as time and date, floppy
`drives, and hard disk drives. Use the arrow keys to highlight the icon labeled Standard, then press
`<Enter>. The following screen appears:
`
` Figure 4. Standard Setup Menu
`
`Date/Time
`This option permits the month, day, year, hour, minute, and second stored in CMOS to be changed.
`Press <Enter> to bring up the modification screen
`then move the cursor to the field you wish to change
`by using the arrow keys. Change the setting by
`using ‘+’ and ‘-’ keys or entering the value directly
`with the keyboard. The time uses a 24 hour clock
`format. For P.M. numbers, add 12 to the hour (4:30
`P.M. is 16:30:00).
`
`13
`
`17
`
`

`
`Floppy Drives A: and B:
`The WINBIOS supports 720KB, 1.44MB, and 2.88MB 3.5 inch
`drives; 360KB, and 1.2MB 5.25 inch drives. Move the cursor to
`either field with the arrow keys and set the appropriate floppy
`drive type using the arrow keys then press <Enter>.
`
`Master and Slave H ard Disks
`Hard disk types from 1 to 46 are industry standard. The USER type is user-definable and can be used
`for both the master and slave drive. If the USER type is selected, the user must enter the proper hard
`drive parameters from the keyboard. The parameters for the USER type under the master hard disk
`and slave hard disk can be different, which allows two different user-definable hard disk drives in the
`system. Not Installed can be used for diskless workstations. The two remaining settings are for
`ESDI and SCSI hard disks. The WINBIOS only supports manual drive parameter selection for hard
`drives connected to the primary IDE channel. Any hard drives connected to the secondary IDE
`channel will be auto detected during POST. The parameters used for these drives will be exactly the
`ones reported by the drive. The user is not allowed to override these settings.
`
`14
`
`18
`
`

`
`Hard Disk Configuration
`
`Hard disks are available with many different types of interfaces and controller options. The WINBIOS
`has built-in support for several of the most common interface standards: IDE/EIDE, SCSI, ESDI and
`ST-506/MFM. In general, depending on the controller used the WINBIOS needs to be configured to
`recognize the hard drives connected.
`
`The most common type of hard disk today uses the IDE or EIDE interface. This type of drive is very
`simple to install and configure. The Nx586 system board supports up to four IDE/EIDE devices using
`a primary and a secondary IDE channel. Each channel supports up to two IDE/EIDE drives or other
`IDE/ATAPI devices such as CDROMs or Tape Backup devices.
`
`Hard drives are identified by several parameters:
`
`Parameter
`
`Description
`
`Type
`
`Cyl - Cylinders
`
`Hd - Heads
`
`WP - Write Precompensation
`
`Lz - Landing Zone
`
`Sec - Sectors
`
`Size
`
`The number designation for a drive with certain identification
`parameters.
`The number of cylinders in the disk drive.
`
`The number of heads.
`
`The size of a sector gets progressively smaller as the track
`diameter diminishes. Yet each sector must still hold 512 bytes.
`Write precompensation circuitry on the hard disk compensates
`for the physical difference in sector size by boosting the write
`current for sectors on inner tracks. This parameter is the track
`number where write precompensation begins.
`This number is the cylinder location where the heads will
`normally park when the system is shut down.
`The number of sectors per track. Hard drives that use MFM
`have 17 sectors per track. RLL drives have 26 sectors per
`track. RLL and ESDI drives have 34 sectors per track. SCSI
`and IDE drives may have even more sectors per track.
`The formatted capacity of the drive based on the following
`formula:
`
`(Number of heads) x (Number of cylinders) x (number of sectors
`per cylinder) x (512 bytes per sector)
`
`Table 3. Hard Drive Configurations
`
`IDE/EIDE drives can be configured simply by using the DetectMaster and DetectSlave commands in
`the Utility Window. Older ST-506/MFM type hard drives require manual selection of these parameters.
`The WINBIOS provides a table with 46 of the most common parameters for these drives. Also a 47th
`entry can be used to enter any configuration not found in the table. Refer to your hard disks manual
`for the proper settings if you have this type of drive.

`

`
`Advanced Setup
`
`This menu permits the user to configure and set some of the more complex settings for system
`components such as floppy drive swapping, system caches, shadow RAM control interrupt mapping.
`Use the arrow keys to highlight the icon labeled Advanced, then press <Enter>. The following screen
`appears:
`
`Figure 5. Advanced Setup Menu, Page 1 of 5
`
`Typematic Rate (Chars/Sec )
`Typematic Rate sets the rate at which characters on the screen repeat when a key is pressed and
`held down. The settings are 15, 20, 24, or 30 characters per second.
`
`System Keyboard
`This option does not specify if a keyboard is attached to the computer. Rather, it specifies if error
`messages are displayed if a keyboard is not attached. This option permits you to configure
`workstations with no keyboards. The settings are Absent or Present.
`
`Primary Display
`Select this icon to configure the type of monitor attached to the computer. The settings are
`Monochrome, Color 40x25, Color 80x25, VGA/PGA/EGA, or Not Installed.
`
`Boot with PnP OS
`This option controls whether the BIOS or the OS gets to configure certain aspects of PnP compatible
`features. In general this option should be set to disabled which permits the BIOS to control the PnP
`features unless you are exclusively using a PnP compatible operating system..
`
`Above 1 MB Memory Test
`When this option is enabled, the WINBIOS memory test is performed on all system memory. When
`this option is disabled, the memory test is done only on the first 1 MB of system memory. The settings
`are Enabled or Disabled.
`
`Memory Test Tick Sound
`This option enables, (turns on) or disables, (turns off) the ticking sound during the memory test. The
`settings are Enabled or Disabled.
`

`
`21
`
`

`
`Parity Error Check
`This option enables or disables parity error checking for system DRAM. The settings are Enabled, (all
`system DRAM parity is checked) or Disabled, (no parity is checked on any system DRAM). Parity
`checking should only be enabled when 36-bit SIMM modules are used. If 32-bit SIMMs are mixed with
`36-bit SIMMs parity checking must be disabled.
`
`Hit “DEL” Message Display
`Disabling this option prevents the message:
`
`
`Hit <DEL> if you want to run Setup
`
`from appearing when the system boots. The settings are Enabled or Disabled.
`
`Extended BIOS RAM Area
`Specify in this option if the top 1 KB of the system programming area beginning at 639K or 0:300 in
`the system BIOS area in low memory will be used to store hard disk information. The settings are Top
`1K or 0:300.
`
`Wait for <F1> If Any Error
`WINBIOS POST runs system diagnostic tests that can generate a message followed by:
`
`Press <F1> to continue
`
`If this option is enabled, WINBIOS waits for the end user to press <F1> before continuing. If this option
`is disabled, WINBIOS continues the boot process without waiting for <F1> to be pressed. The settings
`are Enabled or Disabled.

`
`Keyboard Num Lock
`When On, this option turns off Num Lock when the system is powered on so the end user can use the
`arrow keys on both the numeric keypad and the keyboard. The settings are On or Off.
`
`Floppy Drive Seek At Boot
`When this option is enabled, the WINBIOS performs a Seek command on floppy drive A: before
`booting the system. The settings are Enabled or Disabled.
`
`Floppy Drive Swapping
`When this option is enabled, the WINBIOS will swap the A: and B: floppy drives without the need to
`change any physical cabling or jumpers. This feature is handy when you have two drives of different
`types ( i.e. 1.2MB and 1.44MB) and you need to boot at times from the drive installed as drive B:.
`
`System Boot Up Sequence
`This option sets the sequence of boot drives (either floppy drive A: or hard disk drive C:) that
`WINBIOS attempts to boot from after POST completes. The settings are C:,A: or A:,C:.
`
`System Boot Up CPU Speed
`This option sets the speed of the CPU at system boot time. The settings are High or Low.
`
`L1 & L2 Caches
`This option enables primary CPU and secondary cache memory. If Enabled is selected, the internal
`CPU cache and the external cache memory are enabled. If Disabled is chosen, all cache memory is
`disabled. The settings are Enabled or Disabled.
`
`Password Checking
`This option enables the password check option every time the system boots or the user runs Setup.
`The selections are Always or Setup. If Always is chosen, a user password prompt appears every time
`the computer is turned on. If Setup is chosen, the password prompt appears if WINBIOS setup is
`executed and a password has been entered previously. The Optimal and Fail-Safe default settings are
`Setup.
`
`Video ROM Shadow C000,16K
`Video ROM Shadow C400,16K
`These options when set to Enabled, copy the video ROM area from C0000h - C7FFFh to shadow
`RAM for faster execution. The settings are Enabled or Disabled.

`Shadow CC00,16K
`Shadow D000,16K
`Shadow D400,16K
`Shadow D800,16K
`Shadow DC00,16K
`These options enable shadowing of the contents of the ROM area named in the option title. The
`settings are Enabled or Disabled. The ROM area that is not used by ISA adapter cards will be
`allocated to PCI adapter cards
