Chapter 2
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.
Init Display First
With systems that have multiple video cards, this option determines whether the
primary display uses a PCI Slot or an AGP Slot.
The Choices: PCI Slot (default), AGP.
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.
The Choices: Enabled (default), Disabled.
