On-Chip Primary PCI IDE
If this option is enabled, the primary IDE controller of the board can be used. If an ATAPI-CD-ROM drive is used and
integrated with the secondary IDE channel, hard disk access is not slowed down.
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.

IDEPrimary Master UDMA
This option is used to configure the Ultra-DMA/33 mode of your hard disk. Setting options: Auto, Enabled, Disabled.
The option should be set to Enabled.
IDE Primary Slave UDMA
This option is used to configure the Ultra-DMA/33 mode of your hard disk. Setting options: Auto, Enabled, Disabled.
The option should be set to Enabled.
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.
