BIOS Setup
ECP Mode Use DMA
The ECP mode has to use the DMA channel, so choose the onboard parallel port
with the ECP feature. After selecting it, the following message will appear:
“
ECP
Mode Use DMA.
”
At this time, the user can choose between DMA channel [3] or
[1].
PWRON After PWR-fail
This item specifies whether your system will reboot after a power failure or
interrupt occurs. Available settings are:
[Off]
Leaves the computer in the power off state.
[On]
Leaves the computer in the power on state.
[Former-sts]
Restores the system to the status before power failure
or interrupt occurred.
IDE Devices Configuration
Press <Enter> and the following sub-menu appears:
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 read/
writes per sector the drive can support. Settings: [Enabled], [Disabled].
PCI IDE BusMaster
Set this option to [Enabled] to specify that the IDE controller on the PCI local bus
has bus mastering capability. Settings options: [Disabled], [Enabled].
On-Chip Primary PCI IDE
The integrated peripheral controller contains an IDE interface with support for
two IDE channels. Choose [Enabled] to activate each channel separately. Settings:
[Enabled], [Disabled].
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. Setting options:
[Auto], [Mode 0], [Mode 1], [Mode 2], [Mode 3], [Mode 4].
