Fast PIO 1 ~ 4
Selects the method for transferring the data between the hard disk and
system memory.
The Setup menu only lists those options supported by the drive and
platform.
Ultra DMA
Mode
Disabled
Mode 0 ~ 6
If you install a device that supports UltraDMA, change the appropriate
item on this list to the value listed in the device’s documentation. You may
have to install the UltraDMA driver supplied with this serverboard to use
an UltraDMA device.
Some older drives, do not use Autotyping and require that the end-user select a pre-defined
fixed-disk-type value or specifying the drive parameters separately with the "User" type
option selected. You can find the correct parameters for hard-disk drives in the device's
manual or written on the casing of the drive itself.
NOTE
Once you have established correct parameters for your drive, write them down and store
them in a safe place in case these values are lost in the CMOS or if autotyping fails. If these
parameters are not correctly entered in CMOS, you will NOT be able to access the data on
your drive.
WARNING
Incorrect settings can cause your system to malfunction. To correct mistakes, return to the
Setup and first restore the Setup Defaults with <F9>. Then, enter the correct drive info.
