K8T89-A7 BIOS Setup
IDE Prefetch Mode
The "onboard" IDE drive interfaces supports IDE prefetching for faster drive
access. If the interface does not support prefetching. If you install a primary
and/or secondary add-in IDE interface, set this option to "Disabled".
The Choices: 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 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 Block 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.
