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. Settings: [Enabled], [Disabled].
IDE DMA Transfer Access
This item is used to enable or disable the DMA transfer function of the IDE Hard
Drive. The settings are: [Enabled], [Disabled].
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 optons: [Auto], [Disabled].
