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

”
At this time, the user can choose between DMA channel [3] or
[1].
IDE Devices Configuration
Press <Enter> to enter the sub-menu and the following screen 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. Setting options: [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].
OnChip Primary PCI IDE
The integrated peripheral controller contains an IDE interface with support for
the IDE channel. Choose [Enabled] to activate the channel. Setting options:
[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].
IDE Primary 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 (W indows 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. Setting options: [Auto], [Disabled].
