IDE HDD Block Mode
Enabled The IDE HDD uses the block mode. The system BIOS will check the
hard disk drive for the maximum block size the system can transfer. The
block size will depend on the type of hard disk drive.
Disabled The IDE HDD uses the standard mode.
IDE DMA Transfer Access
This field, when Enabled, will enhance the IDE DMA transfer of an IDE hard disk drive.
On-Chip Primary PCI IDE and On-Chip Secondary PCI IDE
These fields allow you to enable or disable the primary and secondary IDE controller.
Select Disabled if you want to add a different hard drive controller.
IDE Primary Master/Slave PIO and IDE Secondary Master/Slave PIO
PIO means Programmed Input/Output. Rather than have the BIOS issue a series of
commands to effect a transfer to or from the disk drive, PIO allows the BIOS to tell the
controller what it wants and then let the controller and the CPU perform the complete
task by themselves. Your system supports five modes, 0 (default) to 4, which primarily
differ in timing. When Auto is selected, the BIOS will select the best available mode
after checking your drive.
Auto The BIOS will automatically set the system according to your hard disk
drive's timing.
Mode 0-4 You can select a mode that matches your hard disk drive's timing.
Caution: Do not use the wrong setting or you will have drive errors.
IDE Primary Master/Slave UDMA and IDE Secondary Master/Slave UDMA
These fields allow you to set the Ultra DMA in use. When Auto is selected, the BIOS will
select the best available option after checking your hard drive or CD-ROM.
Auto The BIOS will automatically detect the settings for you.
Disabled The BIOS will not detect these categories.
