S.M.A.R.T
32-bit Data
Transfer
Description
Enhances disk performance depending on
the hard disk in use.
If you set this parameter to Auto, BIOS
setup automatically detects if the
installed hard disk drive supports the
Block Mode function. If supported, it
allows data transfer in blocks (multiple
sectors) at a rate of 256 bytes per cycle.
If you set this parameter to Disabled, data
transfer from and to the device occurs
one sector at a time.
When set to Auto, BIOS setup
automatically detects if the installed hard
disk supports the function. If supported, it
allows for faster data recovery and read/
write timing that reduces hard disk activ-
ity time. This results in better hard disk
performance. Mode 0 to 4 provide succes-
sive increases in performance.
Selects DMA (Direct Memory Access)
mode. Options include:
Auto: Auto detected
SWDMAn: SingleWordDMAn
MWDMAn: MultiWordDMAn
UDMAn: UltraDMAn
Enables or disables the S.M.A.R.T (Self-

Technology) function of the internal hard
disk.
If 'Auto' is selected, BIOS setup will
enable the S.M.A.R.T function if the
driver supports it.
Enables or disables the 32-bit data
transfer function
