Ide Hdd Auto Detection - Abit AX5 Instruction Booklet

Introduction of BIOS 3-31
µ IDE HDD Auto Detection
After you have installed the hard disk, in old systems, you had to know the
hard disk specifications, such as the number of cylinders, heads and sectors, and
to enter the relevant information into the hard disk information section. If the
CMOS data were erased, and you had forgotten the hard disk specifications, it
was a great problem. But now, you can use this option to autodetect the hard
disk type and specifications, and the BIOS will automatically detect all the
relevant information and place them in the Hard Disk data section of the
Standard CMOS Setup Menu, in order to allow you to use your hard disk.
