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.
