Description
Block mode is also called block transfer,
multiple compounds 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/write per
sector the drive can support.
This option is used to set up the IDE
transfer access -- with it set to Enabled, the
IDE Transfer Access uses the DMA mode;
with it set to Disabled, the IDE Transfer
Access uses the PIO mode.
Setting the option as Enabled will allow you
to set the sub-menu function settings.
Setting these items to "Auto" activates the
HDD speed auto-detect function. The PIO
mode specifies the data transfer rate of the
HDD. For example, mode 0 data transfer
rate is 3.3MB/s, mode 1 is 5.2 MB/s, mode 2
is 8.3MB/s, mode 3 is 11.1 MB/s and mode
4 is 16.6MB/s. If your hard disk performance
becomes unstable, you may manually try
the slower mode.
These items allow you to set the Ultra DMA
33/66/100 mode supported by the hard disk
drive connected to your primary and
secondary IDE connectors.
Setting the option as Enabled will allow you
to set the sub-menu function settings.
