LBA
Mode
LBA (Logical Block Addressing) mode is used to support IDE hard disks larger than 504 MB.
LBA support is required for compatibility with the FAT32 system. Only some hard disk drives
support LBA mode. The default setting depends on the hard disk drive type.
Blk Mode
Multi-sector transfers enabled
PIO
Mode
PIO (Programmed Input/Output) mode refers to data transfer method used by IDE drives. These
modes use the CPU's registers for data transfer in contrast with DMA (Direct Memory Access),
which transfers directly between main memory and the peripheral device. The default value
Auto lets the system automatically read setup information it needs for setup from the hard disk
drive. Five explicit values, 0 to 4, are also possible.
32Bit
Mode
Enables hard drive 32-bit data transfer. Only some hard disk controllers support 32Bit mode.
