Integrated Peripherals - CHAINTECH 9CJS User Manual

The remaining memory, which is not in use, will be available for the system. For
example, if 16MB is allocated to the AGP card and the card only needs 8MB, the
remaining 8MB will be available for system use.
Init Display First
This function allows users to choose between AGP or PCI slots to initialize monitor
display.
CAS LAN (Giga-LAN)
To enable Giga-Lan port set it as [Enabled], and vice versa.
DRAM Data Integrity Mode
Please leave the default setting as [Non-ECC] for a stable system operation.
Available options are [ECC] and [Non-ECC].

3-4 Integrated Peripherals

This section provides information on setting the peripheral devices. By choosing the
Integrated Peripherals option from the CMOS Setup Utility menu (Figure 3-1), the
screen below is displayed. This sample screen contains the manufacturer's default
values for the motherboard.

Chapter 3
1. 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, select Enabled to
auto-detect the optimal number of block read/writes per sector the drive can
support.
2. IDE DMA transfer access
The onboard IDE drive interfaces supports Prefetching for faster drive accesses.
Set it to [Disabled] if this is a primary or secondary function.
3. On-Chip Primary/Secondary PCI IDE
You can set this to disable the On Chip IDE controller if you are going to add a
higher performance IDE board.
4. IDE Primary/Secondary Master/Slave PIO:
The four IDE PIO (programmed Input/Output) fields let you set a PIO mode (0-4)
for each IDE device that the internal PCI IDE interface supports. Modes 0 through
4 provide successively increased performance. In Auto mode, the system
automatically determines the best mode for each device.
5. IDE Primary/Secondary Master/Slave UDMA:
Ultra DMA implementation is possible only if your IDE device supports it and
your operating environment contains a DMA driver. If both your hard drive and
software support Ultra DMA, select [Auto] to enable BIOS support.
6. On-Chip Serial ATA
Available options are [Disabled], [Auto], [Combined Mode], [Enhanced Mode],
[SATA Only].
Disabled: Disabled Serial ATA controller.
Auto: Auto arrange by BIOS.
Combined Mode: Parallel ATA and serial ATA are combined. Maximum of
two IDE drives are supported.
Enhanced Mode: Enable both serial ATA and parallel ATA. Max of six
IDE drives is supported.
SATA Only: Serial ATA is operating in legacy mode.
7. Serial ATA Port 0 Mode
Please leave the default value as [Primary Master] for a stable system operation.
8. Serial ATA Port 1 Mode
Please leave the default value as [Primary Slave] for a stable system operation.
