IDE Secondary Channel Slave (if installed) is attached to IDE connector 2

NOTE:
The CD/DVD-ROM drive information does not appear among these

to verify the presence of a CD/DVD-ROM drive.
Proceed to the following for details on the parameters under each IDE drive
submenu.
Type
This item specifies the number of cylinders, heads, and sectors, and the
size of a particular IDE drive. If no information appears opposite the
parameters, there is no drive installed in that channel.
Hard Disk Block Mode
This function enhances disk performance depending
on the hard disk in use. BIOS automatically detects if your hard disk supports
this feature.
Setting to Auto allows data transfer in blocks (multiple sectors) to increase the
data transfer rate. If your system does not boot after setting this parameter to
Auto, change the setting to Disabled. The default setting for this parameter is
Auto.
Advanced PIO Mode
The advanced PIO mode feature improves system
performance by allowing the use of faster hard disk drives. If your hard disk
supports this feature, you may set this parameter to Auto (default), Mode 0,
Mode 1, Mode 2, Mode 3, or Mode 4 depending on the hard disk requirements.
See the documentation that came with the hard disk.
If your hard disk does not support this function, set this parameter to Disabled.
Hard Disk Size > 528MB
This enhanced IDE feature works only under DOS
and Windows environments. If set to Auto, which is the default, BIOS allows
you to use a hard disk with a capacity of more than 528 MB. This is made
possible through the Logical Block Address (LBA) mode translation. You may
be required to set this parameter to Disabled if you use other operating
systems.
