BIOS Setup
IDE DMA Transfer Support
This item is used to enable or disable the DMA transfer function of the
IDE Hard Drive. The settings are: Enabled, Disabled.
On-Chip Primary/Secondary PCI IDE
The integrated peripherals controller contains an IDE interface with
support for two IDE channels. Choose Enabled to activate each channel
separately. Setting options: Disabled, Enabled.
IDE Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO
mode (0-4) for each of the four IDE devices that the onboard IDE interface
supports. Modes 0 through 4 provide successively increased performance.
In Auto mode, the system automatically determines the best mode for
each device. The settings are: Auto, Mode 0, Mode 1, Mode 2, Mode 3,
Mode 4.
Primary/Secondary Master/Slave UDMA
Ultra DMA/33 implementation is possible only if your IDE hard drive
supports it and the operating environment includes 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/33, Ultra DMA/
66 and Ultra DMA/100 select Auto to enable BIOS support. The settings
are: Auto, Disabled.
**On-Chip Serial ATA Setting**
On-Chip Serial ATA
This setting is used to specify the SATA controller. Settings: Disable,
Auto, Legacy Mode, Native Mode. If [Legacy Mode] is selected, PATA
and SATA will be combined. If [Native Mode] is selected, PATA and
SATA will both be enabled. If [Auto] is selected, PATA and SATA will
be arranged by BIOS, and you will be able to see the IDE Device status
listed in Standard COMS Features.
