z You are now ready to boot the system for the first time. Please continue to the next

section to configure your BIOS (Basic Input Output System) setting. It must be

configured after booting.

MVBX2-X User’s Manual

6. BIOS Configuration

When you start the computer, it is controlled by the BIOS program. The BIOS first operates

an auto-diagnostic for all the necessary hardware, configures the parameters of the hard-

ware synchronization, and detects all the hardware. Only when these tasks are completed

does it give up control of the computer to program in the next level, which is the operating

system. Since the BIOS is the only channel for hardware and software to communicate, it is

the key factor for system stability, and the assurance to your system good performance.

After the BIOS has achieved the auto-diagnostic and auto-detection operations, pressing

the Del key will allow you to access the BIOS Setup menu. At that point, the BIOS will display

the following message.

Standard CMOS Setup

This “Standard CMOS Setup” option allows you to record some basic configuration of the

system hardware, setting of system clock and error handling. If the motherboard is already

installed in a working system, there is no need to select this option. However, if the configu-

ration stored in the CMOS memory on the board get lost or damaged, or if you change

your system hardware configuration, you will need to reset the configuration values. The

configuration values usually get lost or corrupted when the power of onboard CMOS battery

weakens.

The preceding screen provides you with a list of options. At the bottom of this scrare the

control keys for this screen. Take note of these keys and their respective uses.

z Enter the specifications yourself manually by using the “User” option.

The entries for specifying the hard disk type include CYLS (number of cylinders), HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ (landing zone), SECTOR (number of sectors) and MODE. The SIZE field automatically adjusts according to the configuration you specify. The documentation that comes with your hard disk should provide you with the information regarding the drive specifications. The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI drives. This entry provides three options: Normal, Large, LBA, or Auto (see below). Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it to LBA for drivers over 528MB that support Logical Block Addressing (LBA) to allow larger IDE hard disks; set it to Large for drives over 528MB that do not support LBA. Large type of drive can only be used with MS-DOS and is very uncommon. Most IDE drives over 528MB support the LBA mode.

Auto detection of hard disks on bootup

For each field: Primary Master, Primary Slave, Secondary Master, and Secondary Slave, you can select Auto under the TYPE and MODE fields. This will enable auto detection of your IDE hard disk during bootup. This will allow you to change your hard disks (with the power off) and then power on without having to reconfigure your hard disk type. If you use older hard disks that do not support this feature, then you must configure the hard disk in the standard method as described earlier by the “User” option.

This field sets the time interval for displaying the first and second characters Four delay

rate options are available: 250, 500, 750, and 1000.

Security Option

When you specify a Supervisor Password and/or User Password (explained later in this

section), the Security Option field determines when the system prompts for the password.

The default setting is Setup, where the system goes through its start-up routine unless the

Setup utility is called, then the system prompts for the Supervisor Password. The other

option is System, where the system prompts for the User Password every time you start

your system.

PCI/VGA Palette Snoop

It determines whether the MPEG ISA/PCI VGA Cards can work with PCI/VGA or not.

OS Select For DRAM > 64MB

When using OS/2 operating systems with installed DRAM of greater than 64MB, you need

to set this option to Enabled otherwise leave this on Disabled.

Report No FDD For WIN 95/98

Windows will release IRQ line 6 (normally used by the Floppy Disk Drive) after you disable

your onboard FDD and set this field to “YES”. If you set this field to “NO”, the windows will

reserve INT6 for your FDD.

Video BIOS Shadow

This field allows you to change the video BIOS location from ROM to RAM. Relocating to

RAM enhances system performance, as information access is faster than the ROM.

C8000-CBFFF to DC000-DFFFF

These fields are used for shadowing other expansion card ROMs. If you install other ex-

pansion cards with ROMs on them, you will need to know which addresses the ROMs use

to shadow them specifically. Shadowing a ROM reduces the memory available between

640K and 1024K by the amount used for this purpose.

6. BIOS Configuration

PNP and PCI Setup

This “PNP and PCI Setup” option configures the PCI bus slots. All PCI bus slots on the

system use INTA#, thus all installed PCI cards must be set to this value.

PNP OS Installed

This field allows you to use a Plug-and Play (PnP) operation system to configure the PCI

bus slots instead of using the BIOS. Therefore, interrupts may be reassigned by the OS

when Yes is selected. When a non-PnP OS is installed or to prevent reassigning of interrupt

settings, select the default setting of No.

Resources Controlled By

These fields set how IRQ use is determined for each PCI slot. The default setting for each

field is Auto, which uses auto-routing to determine IRQ use. The other options are manual

settings of NA, 5, 7, 9, 10, 11, 12, 14 or 15 for each slot.

Reset Configuration Data

When Enabled the system BIOS will clear/reset the ESCD during POST. After clearing the

ESCD, the BIOS will then change this item’s value to “Disabled”. Otherwise, the ESCD data

would become useless.

When enabled, up to four Dwords of data can be written to the PCI bus without interrupting

the CPU. When disabled, a write buffer is not used and the CPU read cycle will not be

completed until the PCI bus signals that it is ready to receive the data.

IDE HDD Auto Detection

This “IDE HDD Auto Detection” option detects the parameters of an IDE hard disk drive,

and automatically enters them into the Standard CMOS Setup screen.

Up to four IDE drives can be detected, with parameters for each listed inside the box. To

accept the optimal entries, press <Y> or else select from the numbers displayed under the

OPTIONS field (2, 1, 3 in this case); to skip to the next drive, press <N>. If you accept the

values, the parameters will appear listed beside the drive letter on the screen. The process

then proceeds to the next drive letter. Pressing <N> to skip rather than to accept a set of

parameters causes the program to enter zeros after that drive letter.

Remember that if you are using another IDE controller that does not feature Enhanced IDE

support for four devices, you can only install two IDE hard disk drives. Your IDE controller

must support the Enhanced IDE features in order to use Drive E and Drive F. The onboard

PCI IDE controller supports Enhanced IDE, with two connectors for connecting up to four IDE

devices. IF you want to use another controller that supports four drives, you must disable

the onboard IDE controller in the Chipset Features Setup screen.

When auto-detection is completed, the program automatically enters all entries you ac-

cepted on the field for that drive in the Standard CMOS Setup screen. Skipped entries are

ignored and are not entered in the screen.

If you are auto-detecting a hard disk that supports the LBA mode, three lines will appear in

the parameter box. Choose the line that lists LBA for an LBA drive. Do not select Large or
