!SYSTEM: When you choose System, a password is required each time the computer boots up. If the
correct password is not given, the system will not start.
To disable security, select Set Supervisor Password at main menu and then you will be asked to enter
password. Do not type anything and just press the Enter key and it will disable security. Once security is
disabled, the system will boot and you can enter the BIOS setup menu freely.
Don't forget your password. If you forget the password, you will have to open the computer case and
clear all information in the CMOS before you can start up the system. But by doing this, you will have
to reset all previously set options.
OS Select For DRAM > 64MB:
When the system memory is bigger than 64MB, the communication method between the BIOS and the
operating system will differ from one operating system to another. If you use OS/2, select OS2; if you are
using another operating system, select Non-OS2. The default setting is Non-OS2.
Report No FDD For WIN 95:
When using Windows
setting is No.
Video BIOS Shadow:
This option is used to define whether the BIOS on the video card uses the shadow feature or not. You
should set this option to Enabled, otherwise the display performance of the system will greatly decrease.
Shadowing address ranges:
This option allows you to decide if the ROM BIOS area of an interface card at a specific address uses the
shadow feature or not. If you have no interface card using this memory block, don't enable this option.
You have six address ranges you can select:
C8000-CBFFF Shadow, CC000-CFFFF Shadow, D0000-D3FFF Shadow, D4000-D7FFF Shadow,
D8000-DBFFF Shadow, DC000-DFFFF Shadow.
What is the SHADOW? The BIOS of standard video or interface cards is stored in ROM, and it is
often very slow. With the Shadow feature, the CPU reads the BIOS on the VGA card and copies it
into RAM. When the CPU runs this BIOS, the operation is speeded up.
Delay IDE Initial (Sec):
This item is used to support some old models or special types of hard disks or CD-ROMs. They may need
a longer amount of time to initialize and prepare for activation. Since the BIOS may not detect those
kinds of devices during system booting. You can adjust the value to fit such devices. Larger values will
give more delay time to the device. The minimum number you can enter is 0, the maximum number you
can enter is 15. The default setting is 0.
