Ide Hdd Block Mode - Albatron PM800 Series User Manual

PM800 Series
IDE Prefetch Mode
The "onboard" IDE drive interfaces supports IDE prefetching for faster drive access. If you install a
primary and/or secondary add-in IDE interface, set this option to "Disabled" if the interface does not
support prefetching. Options: Enabled (default)、Disabled
Primary/Secondary/Master/Slave PIO
The IDE PIO (Programmed Input / Output) fields let you set a PIO mode (0-4) for each of the IDE devices
that the onboard IDE interface supports. Modes 0 to 4 will increase performance incrementally. In Auto
mode, the system automatically determines the best mode for each device.
Options: Auto (default)、Mode0、Mode1、Mode2、Mode3、Mode4.
Primary / Secondary /Master / Slave UDMA
Ultra DMA/133 functionality can be implemented if it is supported by the IDE hard drives in your
system. As well, your operating environment requires a DMA driver (Windows 95 OSR2 or a third party
IDE bus master driver). If your hard drive and your system software both support Ultra DMA/133, select
"Auto" to enable BIOS support.
Options: Auto (default)、Disabled

IDE HDD Block Mode

Block mode is otherwise known as block transfer, multiple commands, or multiple sector read/write.
Select the "Enabled" option if your IDE hard drive supports block mode (most new drives do). The
system will automatically determine the optimal number of blocks to read and write per sector.
Options: Enabled (default)、Disabled
