Blistering Ultra DMA/33 HDD Performance
With its integrated Enhanced PCI Bus Master IDE controller that supports
the new Ultra DMA/33 protocol, this mainboard doubles HDD data transfer
rates to 33MB/sec, compared to 16MB/sec for conventional PIO Mode 3,
PIO Mode 4, and DMA Mode 2 devices. By reducing the CPU's workload
and increasing CPU utilization, Ultra DMA/33 significantly improves
system performance when running applications under Windows® 95 and
Windows® NT environments. The Ultra DMA/33 protocol is completely
backward compatible with conventional ATA-2 HDD devices; so the
mainboard also supports existing PIO Mode 3, PIO Mode 4 and DMA Mode
2 devices using the same cable.
With the integrated Enhanced PCI Bus Master IDE controller you can
connect up to four Enhanced IDE peripheral devices to your system. All
devices are categorized in the same way that IDE hard disks were
configured in the past, with one device set as the master device and the other
as the slave device. We recommend that Hard Disk Drives use the primary
IDE connector and that CD-ROM Drives utilize the secondary IDE
connector for optimum system performance.
Concurrent PCI Architecture
The mainboard's Concurrent PCI Architecture enables more efficient
operation of CPU, PCI and ISA transactions for faster and smoother
multimedia performance. It also allows the use of PCI 2.1 and 2.0
compatible add-in cards for long system life, built-in scalability and the
flexibility to adapt your system to future applications.
