NOTE: All the items below are available when you set the item “Primary IDE Master” to
“Manual”.
Cylinder:
When disks are placed directly above one another along the shaft, the circular vertical “slice”
consisting of all the tracks located in a particular position is called a cylinder. You can set the
number of cylinders for a HDD. The minimum number you can enter is 0, the maximum
number you can enter is 65536.
Head:
This is the tiny electromagnetic coil and metal pole used to create and read back the magnetic
patterns on the disk (also called the read/write head). You can configure the number of
read/write heads. The minimum number you can enter is 0, the maximum number you can
enter is 255.
Precomp:
The minimum number you can enter is 0, the maximum number you can enter is 65536.
WARNING: Setting a value of 65536 means no hard disk exists.
Landing Zone:
This is a non-data area on the disk's inner cylinder where the heads can rest when the power is
turned off. The minimum number you can enter is 0, the maximum number you can enter is
65536.
Sector:
The minimum segment of track length that can be assigned to stored data. Sectors usually are
grouped into blocks or logical blocks that function as the smallest units of data permit. You
can configure this item to sectors per track. The minimum number you can enter is 0, the
maximum number you can enter is 255.
Drive A & Drive B:
If you have installed the floppy disk drive here, then you can select the type of floppy drive it
can support.
Floppy 3 Mode Support:
Mode floppy disk drives (FDD) are 3 1/2” drives used in Japanese computer systems. If you
need to access data stored in this kind of floppy, you must select this mode, and of course you
must have a 3 Mode floppy drive.
Video:
You can select the VGA modes for your video adapter.
