AMI BIOS Utility
3-5
Type
This parameter lets you set the IDE device type that your system supports.
The options are User, Auto, CD-ROM, Type 1-46, and Not
Installed. Select Auto to automatically configure the installed hard
disk or IDE device. Select CD-ROM if you have a CD-ROM installed in your
system. If you have an old type HDD installed, you may need to enter the
HDD parameters manually. To do this, you must set this parameter to User.
Select Not Installed to bypass the function.
LBA/Large Mode
This enhanced IDE feature allows the system 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. Set the parameter to Off to disregard
the feature.
This parameter becomes non-configurable when the HDD Type parameter is
set to Auto.
Block Mode
This function enhances disk performance depending on the hard disk in use.
If enabled, it allows data transfers in block (multiple sectors) by increasing the
data transfer rate to 256 bytes/cycle. However, if your hard disk does not
support this function, set this parameter to Off.
This parameter becomes non-configurable when the HDD Type parameter is
set to Auto.
