PCI-953 Single Board Computer User’s Guide
When you enter the Advanced Menu, it usually displays the results of
Autotyping
– information
each drive provides about its own parameters, such as cylinders, heads, and sectors, and how the
drives are arranged as Masters or Slaves on your machine.
Some older drives, however, do not use Autotyping and require selecting type User and entering
a pre-defined fixed-disk type value, such as 1 to 39, or specifying the drive parameters
separately with the User type selected. You can find the correct parameters for hard-disk drives
in the drive manual or written on the casing of the drive itself.
LBA Mode Control In LBA mode, the maximum hard disk capacity is
137GB. For drive capacities over 137GB your BIOS
must have 48-bit LBA mode addressing.
Block Mode Block mode boosts IDE performance by
increasing the amount of data transferred. Only
512b of data can be transferred per interrupt if
block mode is not used. Block mode allows
transfers of up to 64Kb per interrupt.
PIO Mode This function programs timing cycles between the
IDE drive and the programmable IDE controller.
As PIO mode increases, the cycle time decreases.
Async DMA This indicates the highest Asychronous DMA
mode is supported.
Ultra DMA Mode This indicates the highest Sychronous DMA mode
is supported.
SMART Self Monitoring Analysis and Reporting
Technology protocol used by some manufacturers
to predict drive failures.
