IDD HDD Auto-Detection

If you want the Setup Utility to automatically detect and configure a hard disk drive
on the IDE channel, press <

Enter

> while this item is highlighted.

If your system has an IDE hard drive, you can use this utility to detect its param-
eters and enter them into the Standard CMOS Setup automatically.
If the auto-detected parameters displayed do not match the ones that should be
used for your hard drive, do not accept them.  Press the <

N

> key to reject the

values and enter the correct ones manually in the Standard CMOS Setup screen.
(

Note: 

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.)
Do not choose 

Large

 or 

Normal

 if the hard disk drive is already fully formatted

when you installed it.  Select the mode that was used to format it.

IDE Primary/Secondary Master/Slave

If you leave this item at 

Auto

, the system will automatically detect and configure

any IDE devices it finds. If it fails to find a hard disk, change the value to 

Manual

and then manually configure the drive by entering the characteristics of the drive in
the items below:

         Capacity                      approximate hard disk drive capacity
         Cylinder                      number of cylinders
         Head                            number of heads
         Precomp                      write precompensation cylinder
        Landing Zone             landing zone

         Sector                          number of sectors
