data at a maximum burst rate of 100 MB/sec.
If you encounter the problem of using Ultra DMA devices, you can try to set this item to Disabled .
When you select Auto, the system automatically determines the optimal data transfer rate for each
IDE device. This field is not available to enter when the “
Internal PCI/IDE
” field is Disabled or
Primary .
Secondary Slave Ultra DMA:
Two options are available: Disabled or Auto. The default setting is Auto . Ultra DMA is a DMA data
transfer protocol that utilizes ATA commands and the ATA bus to allow DMA commands to transfer
data at a maximum burst rate of 100 MB/sec.
If you encounter the problem of using Ultra DMA devices, you can try to set this item to Disabled .
When you select Auto, the system automatically determines the optimal data transfer rate for each
IDE device. This field is not available to enter when the “
Internal PCI/IDE ” field is Disabled or
Primary .
IDE Burst Mode:
Two options are available: Disabled or Enabled. The default setting is Enabled . Selecting Enabled
reduces latency between each drive read/write cycle, but may cause instability in IDE subsystems that
cannot support such fast performance. If you are getting disk drive errors, try setting this value to
Disabled. This field is not available to enter when the “
Internal PCI/IDE ” field is Disabled .
SiS OnChip PCI Device:
AC97 AUDIO:
Two options are available: Enabled or Disabled. The default setting is Enabled . Your motherboard has the
built-in AC97 Codec that can support AC97 specifications. If you set this controller to Enabled , you can
