BIOS SETUP 3-6. SUPERVISOR/USER PASSWORD The I( SUPERVISOR/USER PASSWORD SETTING ’ utility sets the password. The mainboard may be shipped with the default password “award-SW” , or with the password disabled. If you want to change the password, you must first enter the current password (” award_sw ” in this case). Then at the prompt, type your new password. The password is case sensitive and you can use up to 8 alphanumeric characters. Press after the password . At the next prompt, confrnn the new password by typing it and pressing again. when you use this feature, the ” security option” line in BIOS FEATURES SETUP will determine whether the password will be required. To disable the password, press the key instead of entering a new password when the ” Enter password” dialog box appears. A message will appear confuming that the password is disabled. You may receive your mainboard set up this way. There are two kinds of password functions in the setup menu : one is SUPERVISOR PASSWORD, and the other is USER PASSWORD. The differences between them are: SUPERVISOR PASSWORDThe supervisor password function allows you the right to change the options of setup menu once you enter the setup menu. USER PASSWORDThe user password function only allows you to enter the setup menu but do not have the right to change the options of the setup menu except user password save 8c exit setup, and exit without saving. 143OVX PAGE 18 I43OVX PAGE 19

3-9 .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 INSTALLED IN THE SYSTEM AUTOMATICALLY OR YOIJ CAN SET HARD DISK TYPE TO AUTO IN THE STANDARD CMOS SETUP. YOU DON’T NEED THE “IDE HDD AUTO DETECTION” UTILITY. THE BIOS WILL AUTO-DETECT THE HARD DISK SIZE AND MODEL ON DISPLAY DURING POST. 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! LBA (LOGICAL Block Addressing) mode 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. CHAPTER 3. BIOS SETUP DURING HDD ACCESSING, THE IDE CONTROLLER WILL TRANSFORM THE LOGICAL ADDRESS DESCRIBED BY SECTOR, HEAD & CYLINDER 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. CYLINDER (1024) X no. HEAD ( 255) X no. SECTOR ( 63) X no. Bvtes PER SECTOR ( 512) 8.4 GIGABYTES EXTENDED HDD ACCESS MODE SUPPORTED BY AWARD SOFTWARE.

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 MlJLTIPLIED BY 2. A 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 no. BYTES PER SECTOR ( 512) 1 Gigabytes 143OVX PAGE 22 143OVX PAGE 23

NOTE: TO SUPPORT LBA OR LARGE MODE OF HDDS, THERE MUST BE SOME SOFTWARES INVOL\‘ED. ALL THESE SOFTWARES ARE LOCATED IN THE AWARD HDD SERVICE ROUTINE (MT 13H). IT MAY BE FAILED TO ACCESS A HDD WITH LBA (LARGE) MODE SELECTED IF YOU ARE RUNNING UNDER AN OPERATING SYSTEM WHICH REPLACES THE WHOLE INT 13H. UNIX OPERATING SYSTEMS DO NOT SUPPORT EITHER LBA OR LARGE AND MUST UTILITY THE STANDARD MODE. UNIX CAN SUPPORT DRIVES LARGER THAN 528MB. 3-10 .LOAD SETUP DEFAULTS “LOAD SETUP DEFAULTS” loads optimized settings which are stored in the BIOS ROM. THE AUTO-CONFIGURED SETTINGS ONLY AFFECT THE BIOS FEATURE SETUP AND CHIPSET FEATURES SETUP SCREENS. THERE IS NO EFFECT ON THE STANDARD CMOS SETUP. TO USE THIS FEATURE, HIGHLIGHT IT ON THE MAIN SCREEN AND PRESS THE KEY. A LINE WILL APPEAR ON SCREEN ASKING IF YOU WANT TO LOAD THE SETUP DEFAULT VALUES. PRESS THE KEY AND THEN PRESS THE KEY. THE SETUP DEFAULTS WILL THEN LOAD. PRESS IF YOU DON’T WANT TO 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. 3-12 EXIT WITEOUT SAVING THE “EXIT WITHOUT SAVING” OPTION WILL BRING YOU BACK TO NORMAL BOOT UP PROCEDURE WITHOUT SAVING ANY DATA INTO CMOS RAM.
