K8VBK-S7 BIOS Setup
5.1.5 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.
5.1.6 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.
5.1.7 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.
