IDE HDD Block Mode
This option is used to activate block mode for IDE hard disks. If your drive supports this mode and this option
is activated, the system will read the number of blocks per request from the configuration sector of the hard
disk. The recommended setting is Enabled, although it should be noted that this is not suitable for older hard
disks.
IDE Primary Master PIO
PIO refers to the concept of programmed input and output. Instead of the BIOS issuing an instruction
sequence for initiating a data transfer from or to the hard disk, PIO enables the BIOS to notify the controller
what task should be executed. The task is then fully handled by the controller and the CPU. Your system
supports five PIO modes, 0 (standard) to 4, with the main difference relating to timing. If "Auto" (automatic) is
selected, the BIOS will assess your drive and automatically specify the optimum PIO mode. Auto: The BIOS
automatically sets the system value depending on the timing of your hard disk drive. Mode 0-4: You can
select a mode suitable mode that matches the timing your hard drive.
