P4M800 Pro-M7 BIOS SETUP
24
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 progressively. In Auto mode, the system automatically
determines the best mode for each device.
The Choices: Auto
(default), Mode0, Mode1, Mode2, Mode3, Mode4.
Primary / Secondary /Master / Slave UDMA
Ultra DMA/100 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/100, select Auto to enable BIOS
support.
The Choices: Auto
(default), Disabled.
IDE HDD B lock Mode
Block mode is also called block transfer, multiple commands, or multiple sector
read / write. If your IDE hard drive supports block mode ( most new drives do),
select Enabled for automatic detection of the optimal number of block mode (most
new drives do), select Enabled for automatic detection of the optimal number of
block read / write per sector where the drive can support.
The Choices: Enabled
(default), Disabled.
