Using BIOS
Access Mode (Auto)
This item defines ways that can be used to access IDE hard disks such as LBA (Large Block
Addressing). Leave this value at Auto and the system will automatically decide the fastest
way to access the hard disk drive.
Drive A (1.44M, 3.5 in.)
These items define the characteristics of any diskette drive attached to the system.
You can connect one or two diskette drives.
Floppy 3 Mode Select (Disabled)
Floppy 3 Mode refers to a 3.5-inch diskette with a capacity of 1.2MB. Floppy 3 mode
is sometimes used in Japan.
Video (EGA/VGA)
This item defines the video mode of the system. This motherboard has a built-in VGA
graphics system; you must leave this item at the default value.
Halt On (All, But Keyboard)
This item defines the operation of the system POST (Power On Self Test) routine. You
can use this item to select which types of errors in the POST are sufficient to halt the
system.
Base Memory, Extended Memory, and Total Memory
These items are automatically detected by the system at start up time. These are
display-only fields. You cannot make changes to these fields.
IDE Channel 0/1/2/3/4/5 Master & IDE Channel 0/1 Slave
Leave this item at Auto to enable the system to automatically detect and configure IDE
devices on the channel. If it fails to find a device, change the value to Manual and then
manually configure the drive by entering the characteristics of the drive in the items
described below.
Before attempting to configure a hard disk drive, ensure that you have the
configuration information supplied by the manufacturer of your hard drive.
Incorrect settings can result in your system not recognizing the installed
hard disk.
If you are setting up a new hard disk drive that supports LBA mode, more
than one line will appear in the parameter box. Choose the line that lists
LBA for an LBA drive.
