Integrated Peripherals Setup
SIS 630 OnChip IDE Device
Internal PCI / IDE
This chipset contains an internal PCI IDE interface with support for two
IDE channels.
The choice: Primary, Secondary, Both.
IDE Primary 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 choice: Auto, Mode 0, Mode 1, Mode 2, Mode 3, and Mode 4.

Primary Master/Slave UltraDMA
UDMA (Ultra DMA) is a DMA data transfer protocol that utilizes ATA commands
and the ATA bus to allow DMA commands to transfer data at a maximum burst
rate of 33 MB/s. When you select
Auto
in the four IDE UDMA fields (for each of
up to four IDE devices that the internal PCI IDE interface supports), the system
automatically determines the optimal data transfer rate for each IDE device.
The choice: Auto, Disabled.
IDE Burst Mode
Selecting
Enabled
reduces latency between each drive’s read/write cycle,
but may cause instability in IDE subsystems that cannot support such
fast performance. If you are getting disk drive errors, try setting this
value to
Disabled.
This field does not appear when the Internal PCI/IDE
field, above, is
Disabled.
The choice: Enabled, Disabled.
SIS 630 OnChip PCI Device
SIS-7018 AC97 AUDIO
Select
Enabled
to support AC97 Audio.
The choice: Enabled, Disabled.
Super I/O Device
Onboard FDC Controller
Select Enabled if your system has a floppy disk controller (FDC) installed
on the system board and you wish to use it. If you uninstall the FDC or
the system has no floppy drive, select Disabled in this field.
The choice: Enabled, Disabled.
Onboard Serial Port 1/ Port 2 / Port 3 / Port 4
Select an address and corresponding interrupt for the first and second
serial ports.
