primary IDE channel, “Pri Slave” - the second. Sec Master and Sec Slave specify
the devices on the secondary channel.
The first option available is the most important: Type . This is where you will
specify the type of device and how it is represented in the BIOS Setup. If the device
is a hard disk or CD-ROM, generally the Auto option is the best choice for fast and
easy setup of the hard disk parameters. Let’s take a look at the difference between
the Auto, User and Types (1-45) options:
•
Auto - This option instructs the BIOS to automatically configure the hard disk
by reading the parameters (cylinders, sectors, etc.) directly from the hard
disk’s firmware. Use this option if you are configuring a new hard drive, or
one that has already been formatted using the
Auto option. Keep in mind that a
hard drive is configured using a certain set of parameters, those same
parameters must be used for the life of the drive, unless the drive is re-
FDISKed using a different parameter set. (This procedure deletes the old
partition(s) on the drive and creates a new one, using the new parameters).
•
User - This option allows you to
manually enter in the parameters of
the hard drive. Generally, this option
would be used only if the hard drive
has already been formatted with a
certain set of parameters, and assured
consistency between the old and new
parameters is desired.
•
Types 1-45 - Similar to the User option, these types should only be used if the
exact parameters for the hard drive are already entered as a specific type stored
in the Setup Program. Again, this would only be needed to assure that the
parameters the drive was formatted with and those it is using now, are
identical. For new hard drives, the
Auto option is the preferred choice.
Mode - One of Enhanced IDE’s most important features is LBA (Logical Block
Addressing) Mode. This feature allows the use of larger hard drives by providing a
way to bypass the cylinder limitations imposed by many Operating Systems. LBA
Mode is used to extend a hard drive’s useable capacity by “remapping” the
cylinders in a way that is acceptable to these operating systems. For instance, a
hard drive with the parameters of 2100 Cylinders, 16 Heads and 63 Sectors would
be represented by LBA Mode as 525 Cylinders, 64 Heads and 63 Sectors. (Notice
