Chapter 3 AWARD BIOS SETUP Award's ROM BIOS provides a built-in Setup program which allows user modify the basic system configuration and hardware parameters. The modified data will be stored in a battery-backed CMOS RAM so data will be retained even when the power is turned off. In general, the information saved in the CMOS RAM stay unchanged unless here is configuration change in the system, such as hard drive replacement or new equipment is installed. It is possible that CMOS had a battery failure which cause data lose in CMOS_RAM. If so, re_enter system configuration parameters become necessary.
To enter Setup Program Power on the computer and press <Del> key immediately will bring you into BIOS CMOS SETUP UTILITY.
Figure 3-1 The menu displays all the major selection items and allow user to select any one of shown item. The selection is made by moving cursor (press any direction key) to the item and press <Enter> key. An on_line help message is displayed at the bottom of the screen as cursor is moving to various items which provides user better understanding of each function. When a selection is made, the menu of selected item will appear so the user can modify associated configuration parameters. STANDARD CMOS SETUP
Choose " STANDARD CMOS SETUP " in the CMOS SETUP UTILITY Menu (Figure 3-1). The STANDARD CMOS SETUP allows user to configure system setting such as current date and time, type of hard disk drive installed in the system, floppy drive type, and the type of display monitor. Memory size is auto-detected by the BIOS and displayed for your reference. When a field is highlighted (direction keys to move cursor and <Enter> key to select), the entries in the field will be changed by pressing <PgDn> or <PgUp> keys or user can enter new data directly from the keyboard.
Figure 3-2 BIOS FEATURES SETUP Select the " BIOS FEATURES SETUP " option in the CMOS SETUP UTILITY menu allows user to change system related parameters in the displayed menu. This menu shows all of the manufacturer's default values of J-656VXD/J-656VXDP. Again, user can move the cursor by pressing direction keys and <PgDn> of <PgUp> keys to modify the parameters. Pressing [F1] key to display help message of the selected item. This setup program also provide 2 convinent ways to load the default parameter data from BIOS [F6] or CMOS [F7] area if shown data is corrupted. This provides the system a capability to recover from any possible error.
Figure 3-3 Note: The Security Option contians "setup" and "system". The "setup" indicates that the password setting is for CMOS only while the "system" indicates the password setting is for both CMOS and system boot up procedure. · Virus Warning: This category flashes on the screen. During and after the system boots up, any attempt to write to the boot sector or partition table of the hard disk drive will halt the system and the following error message will appear, in the mean time, you can run an anti-virus program to locate the problem. Default value is Disabled Enabled: Activates automatically when the system boots up causing a warning message to appear when anything attempts to access the boot sector or hard disk partition table. Disabled: No warning message to appear when anything attempts to access the boot sector or hard disk partition table. · CPU Internal Cache / External Cache: These two categories speed up memory access. However, it depends on CPU/chipset design. The default value is Enable. If your CPU without Internal Cache then this item "CPU Internal Cache" will not be show. Enabled: Enable cachehis category speeds up Power On Self Test. (POST) after you power on the computer. Disabled: Disable cache · Quick Power On Self Test: If it is set to Enable, BIOS will shorten or skip some check items during POST. Enabled: Enable quick POST Disabled: Normal POST · Boot Sequence: This category determines which drive computer searches first for the DOS (Disk Operating System). Default value is A,C. A,C: System will first search for floppy disk drive then hard disk drive. C,A: System will first search for hard disk drive then floppy disk drive. · Swap Floppy Drive: The swap floppy drive. Default value is Disabled. Enabled: Floppy A & B will be swapped under the DOS Disabled: Floppy A & B will be not swap · Boot Up Floppy Seek: During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360K type is 40 tracks while 760K, 1.2M and 1.44M are all 80 tracks. The default value is Enabled. Enabled: BIOS searches for floppy disk drive to determine if it is 40 or 80 tracks. Note that BIOS can not tell from 720K, 1.2M or 1.44M drive type as they are all 80 tracks.
Disabled: BIOS will not search for the type of floppy disk drive by track number. Note that there will not be any warning message if the drive installed is 360K. · Boot Up NumLock Status: The default value is On. On: Keypad is number keys. Off: Keypad is arrow keys. · Boot UP System Speed: It selects the default system speed-the speed that the system will run at immediately after power up. High: Set the speed to high. Low: Set the speed to low. CHIPSET FEATURES SETUP Choose the " CHIPSET FEATURES SETUP " in the CMOS SETUP UTILITY menu to display following menu.
Figure 3-4 · DRAM Timing: The default value is 60ns. 60ns: 2 (faster) Burst Wait State, for 60~70ns Fast Page Mode/EDO DRAM. 70ns: 3 (slower) Burst Wait State, for 70ns Fast Page Mode/EDO DRAM. · Video BIOS Cacheable: The default value is Enabled. Enabled: This field Enabled the Video BIOS Cacheable to speed up to VGA Performance. Disabled: Disabled the Video BIOS Cacheable function. · 8/16 Bit I/O Recovery Time: The default value is 1. 8 Bit I/O Recovery Time: This field defines the recovery time from 1 to 8 for 8-bit I/O. 16 Bit I/O Recovery Time: To define the recovery time from 1 to 4 for 16-bit I/O. · Memory Hole At 15M~16M: The default value is Disabled. Disabled: Normal Setting. Enabled: This field enableds the main memory (15~16MB) remap to ISA BUS.
POWER MANAGEMENT SETUP Choose the " POWER MANAGEMENT SETUP " in the CMOS SETUP UTILITY to display the following screen. This menu allows user to modify the power management parameters and IRQ signals. In general, these parameters should not be changed unless it's absolutely necessary.
Figure 3-5 Again, user can move the cursor by pressing direction keys to the field need to be modified and press <PgDn> or <PgUp> to alter item selection. You can only change the content of Doze Mode, Standby Mode, and Suspend Mode when the Power Management is set to 'User Define'. HDD Standby HDD Standby timer can be set from 1 to 15 minute(s). System Doze The "System Doze" mode timer starts to count when there is no "PM events" occurred. The valid timeout setting is from 1 minute up to 1 hour. System Standby The "Standby" mode timer starts to count when "System Doze" mode timer timed out and no "PM events" occurred. Valid range is from 1 minute up to 1 hour. System Suspend This function works only when the Pentium CPU is installed. The timer starts to count when "System Standby" mode timer timed out and no "PM Events" occurred. Valid range is from 1 minute up to 1 hour.
HDD Standby Mode When system stop reading or writing HDD, the timer starts to count. The system will cut off the HDD power when timer ran out of time. The system will not resume operation until either a read from or a write to HDD command is executed again. Doze Mode The system hardware will drop down CPU clock from normal working speed when Doze mode timeout occurred. Standby Mode When the system standby mode timer ran out, it will enter the standby mode and retain CPU at slow working speed. The screen will be blanked out. Suspend Mode When the system suspend timer time out, the system will enter the suspend mode and the chipset will stop CPU clock immediately. The power consunption in Suspend Mode is lower than in standby mode. The screen is also blanked out. PM Events: AWARD BIOS defines 15 PM Events in the power management mode (Doze, standby & suspend). The user can initial any PM Events to be "Enable" or "Disable". When the system detects all of the enabled events do not have any activity, it will start the system Doze timer first if the "Power Management" isn't "Disabled". Once the system Doze timer timed out, it will process doze power saving procedure by starting the system standby timer. When the standby timer ran out and all of the "Enabled" events remains silent, the system will enter the standby mode. By now, the system will not only process the standby power saving procedures but also start the system suspend timer. When the suspend timer time out, all of the CPU clock will be stopped by dropping system clock down to zero and remains this way until any one of the "Enabled" event occurred.
PNP/PCI CONFIGURATION SETUP
This “PNP and PCI configuration 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.
Figure 3-6 IRQxx assigned to These fields indicate whether or not the displayed IRQ for each field is being used by a Legacy (non-PnP) ISA card. Two options are available: “PCI/ISA PnP” and “Legacy ISA”. The first option the default value, indicates either that the displayed IRQ is not used or an PCI/ISA PnP is being used to determine if an ISA card is using that IRQ. Second option is for Legacy ISA card that requires a unique IRQ, and you are not using an PCI/ISA PnP, you must set the field for that IRQ to Legacy ISA. For example: If you install a Legacy ISA card that requires IRQ10 lets say, then set “IRQ10 assigned to Legacy ISA”. DMAxx assigned to These fields indicate whether or not the displayed DMA channel for each field is being used by a Legacy (non-PnP) ISA card. Available options include: “PCI/ISA PnP” and ”Legacy ISA“. When is option ”PCI/ISA PnP“ indicates either that the displayed DMA channel is not used or an PCI/ISA PnP being used to determine if an ISA card is using that channel. If you install a Legacy ISA card that requires a unique DMA channel, and you are not using an PCI/ISA PnP, you must set the field for that channel to “Legacy ISA“. LOAD BIOS DEFAULTS The " LOAD BIOS DEFAULTS " function loads the system default data directly from ROM and initialize associated hardware properly. This function will be necessary only when the system CMOS data is corrupted.
Figure 3-7
LOAD SETUP DEFAULTS The " LOAD SETUP DEFAULTS " function loads the system default data directly from ROM and initialize associated hardware properly. This function will be necessary only when the system CMOS data is corrupted.
Figure 3-8 Figure 3-9 NOTE: If you don't use the Onboard IDE connector, than use On-card (PCI or ISA card) IDE connector. You will set Onboard Primary IDE: Disabled an Onboard Secondary IDE: Disabled from CHIPSET FEATURES SETUP UTILITY. SUPERVISOR/USER PASSWORD This item lets you configure the system so that a password is required each time the system boots or an attempt is made to enter the Setup program (Refer to Figure 3-3 for the details). Supervisor Password allows you to change all CMOS settings but the User Password setting doesn’t have this function. The way to set up the passwords for both Supervisor and User are as follow: 1. Choose either Supervisor Password or User Password in the Main Menu and press <Enter>. The following message appears: “ Enter Password: ” 2. The first time you run this option, enter your password up to only 8 characters and press <Enter>. The screen does not display the entered characters. For no password just press <Enter>. 3. After you enter the password, the following message appears prompting you to confirm the password: “ Confirm Password: ” 4. Enter exact the same password you just typed again to confirm the password and press <Enter>. 5. Move the cursor to Save & Exit Setup to save the password. 6. If you need to delete the password you entered before, choose the Supervisor Password and Press <Enter>. It will delete the password that you bad before. 7. Move the cursor to Save & Exit Setup to save the option you did, otherwise the old password will still be there when you turn on your machine next time.
IDE HDD AUTO DETECTION The "IDE HDD AUTO DETECTION" utility is a very useful tool especially when you do not know which kind of hard disk type you are using. You can use this utility to detect the correct disk type and install in the system automatically. Also you can set HARD DISK TYPE to “Auto” in the STANDARD CMOS SETUP to have same result. The BIOS will Auto-detect the hard disk size and model on display during POST.
Figure 3-10 NOTE: HDD Modes The Award BIOS supports 3 HDD modes: NORMAL, LBA & LARGE NORMAL mode Generic access mode in which neither the BIOS nor the IDE controller will make any transformations during accessing. The maximum number of cylinders, head & sectors for NORMAL mode are 1024, 16 & 63. no. Cylinder (1024) x no. Head (16) x no. Sector (63) x no. per sector (512) 528 Megabytes If user set this HDD to NORMAL mode, the maximum accessible HDD size will be 528 Megabytes even though its physical size may be greater than that! LARGE mode Extended HDD access mode supported by Award Software. Some IDE HDDs contain more than 1024 cylinder without LBA support (in some cases, user do not want LBA). The Award BIOS provides another alternative to support these kinds of LARGE mode: CYLS. HEAD SECTOR MODE 1120 16 59 NORMAL 560 32 59 LARGE BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by dividing it by 2. At the same time, the number of heads is nultiplied by 2. Reverse transformation process will be made inside INT 12h in order to access the right HDD address the right HDD address! Maximum HDD size: no. Cylinder (1024) x no. Head (32) x no. Sector (63) x bytes per sector (512) 1 Gigabytes NOTE: To support LBA or LARGE mode of HDDs, there must be some softwares involved. All these softwares are located in the Award HDD Service Routine (1NT 13h). It may be failed to access a HDD with LBA (LARGE) mode selected if you are running under a Operating System which replaces the whole INT 13h. UNIX operating systems do not support either LBA or LARGE and must set to the Standard mode. UNIX can support drives larger than 528MB. 3-11 SAVE & EXIT SETUP
The "SAVE & EXIT SETUP" option will bring you back to boot up procedure with all the changes you just made which are recorded in the CMOS RAM.
EXIT WITHOUT SAVING
The "EXIT WITHOUT SAVING" option will bring you back to normal boot up procedure without saving any data into CMOS RAM. All of the old data in the CMOS will not be destroyed.
