Although secondary monitor is supported, you do not have to select the type in Setup. You have two ways to boot up the system: ��� When you have VGA as primary and monochrome as secondary, the selection of the video type is “VGA Mode”. ��� When you have monochrome as primary and VGA as secondary, the selection of the video type is ”Monochrome mode”. EGA/VGA Enhanced Graphics Adapter/video Graphics Array. For EGA, VGA, SEGA, or PGA monitor adapters. Absent The system will discard the VGA adaptor. CGA 80 Color Graphics Adapter, power up in 80 column mode MONO Monochrome adapter, includes high resolution monochrome adapters Error halt This category determines whether the computer will stop if an error is detected during power up. No errors Whenever the BIOS detects a non-fatal error the system will be stopped and you will be prompted. All errors The system boot will not be stopped for any error that may be detected. All, But Keyboard The system boot will not be stopped for a keyboard error; it will be stopped for all other errors. All, But Diskette The system boot will not be stopped for a disk error; it will be stopped for all other errors. All, But Disk/Key The system boot will not be stopped for a keyboard or disk error; it will be stopped for all other errors. Memory The category is display-only which is determined by POST (Power On Self Test) of the BIOS. Base Memory The POST of the BIOS will determine the amount of base (or conventional) memory installed in the system. The value of the base memory is typically 512K for systems with 512K memory installed on the motherboard, or 640K for systems with 640K or more memory installed on the motherboard. Extended Memory The BIOS determines how much extended memory is present during the POST. This is the amount of memory located beyond 1MB in the CPU's memory address map. Other Memory This refers to the memory located in the 640K to 1024K address space. This is the memory that can be used for different applications. DOS uses this area to load device drivers to keep as much base memory free for application programs. Most use for this area is Shadow RAM. Total Memory System total memory is the sum of basic memory, extended memory, and other memory. BIOS Features Setup Menu ROM PCI/ISA BIOS BIOS FEATURES SETUP AWARD SOFTWARE, INC.

IDE HDD Auto Detection The Enhance IDE features was included in all Award BIOS. The following is a brief description of this feature. 1. Setup Changes Auto-detection BIOS setup will display all possible modes that are supported by the HDD including NORMAL, LBA & LARGE. If HDD does not support LBA modes, no ’LBA’ option will be shown. If the number of cylinders is less than or equal to 1024, no ‘LARGE’ option will be shown. Users can select a mode which is appropriate for them.

(2) HDD Modes The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE NORMAL mode This is the generic access mode in which neither the BIOS nor the IDE controller will make any transformation during accessing. The maximum number of cylinders, head & sectors for NORMAL mode are 1024, 16 & 63. no. Cyclinder (1024) x no. Head ( 16) x no. Sector ( 63) x no. per sector ( 512) 528 Megabytes If a user set his HDD to NORMAL mode, the maximum accessible HDD size will be 528 Megabytes even though its physical size may be greater than that. LBA (Logical Block Addressing) mode This is a new HDD accessing method to overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors shown in setup may not be the number physically contained in the HDD. During HDD accessing, the IDE controller will transform the logical address described by sector, head & cylinder number into its own physical address inside the HDD. The maximum HDD size supported by LBA mode is 8.4 Gigabytes which is obtained by the following formula: no. Cyclinder ( 1024) x no. Head ( 255) x no. Sector ( 63) x bytes per sector ( 512) 8.4 Gigabytes LARGE mode This is a extended HDD access mode supported by the Award Software. Some IDE HDDs contain more than 1024 cylinder without the LBA support (in some cases, user do not want LBA). The Award BIOS provides another alternative to support these kinds of HDD. Example of LARGE mode: CYLS. HEADS 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 multiplied by 2. A reverse transformation process will be made inside INT13h in order to access the right HDD address. Maximum HDD size: no. Cyclinder ( 1024) x no. Head ( 32) x no. Sector ( 63) x bytes per sector ( 512) 1 Gigabytes (3) Remarks To support LBA or LARGE mode of HDDs, there must be some software involved. All these software are located in the Award HDD Service Routine (INT 13h). You may not be able to access a HDD with LBA (LARGE) mode selected if you are running under a Operating System which replaces the whole INT 13h.

It is defined at I/O port 0443H and 043H to enable/disable the watchdog time out function. Regarding to the watchdog function, user must have a program to set the watchdog time out value, and refresh the watchdog timer cycle. If the system program goes into a dead loop or goes into an abnormal cycle, the watchdog timer cannot be refreshed immediately. Meanwhile, the system will be reset by watchdog timer automatically. The watchdog timer will be refreshed by “disable watchdog output” then “enable watchdog output”. The following flowchart shows the normal structure of system program. Watchdog timer examples: (1) Setup watchdog timer time out value: mov al,0ah mov dx,70h out dx,al jmp short $+2 mov dx,71h in al,dx jmp short $+2 and al,0f0h add ax,TimeValue ; TimeValue= 00h..0fh, reference as following watchdog time out table out dx,al jmp short $+2 mov al, 0bh mov dx, 70h out dx, al �jmp short $+2 mov dx, 71h in al, dx jmp short $+2 or al, 08h out dx, al jmp short $+2 Watchdog Time Out Table: Time Value Time Out Time Value Time Out 0 None 8 0.5 sec. 1 0.5 9 1 sec. sec. 2 1 A 2 sec. sec. 3 0.015 B 4 sec. sec. 4 0.03 C 8 sec. sec. 5 0.06 D 16 sec. sec. 6 0.125 E 32 sec. sec. 7 0.25 F 64 sec. sec. 6�8� Enable watchdog output: mov dx, 443h ; SET WATCH DOG ENABLE in al, dx jmp short $+2 (3) Disable watchdog output: mov dx,043h ; SET WATCH DOG DISABLE in al,dx jmp short $+2 Appendix B Connectors’ Pin Assignment Parallel/Printer connector (PRN) Pin no.
