1-6 Features of Your System
The system’s integrated bit-block transfers (BitBLT)
graphics accelerator, IDE controller, and Fast SCSI-2 host
adapter use the 32-bit PCI local bus, which increases sys-
tem performance and frees the Pentium processor for other
system activities.
The PCI bus is linked to the EISA bus through the
PCI/EISA Bridge Component link and the EISA System
Component link. The links allow concurrent operation.
EISA Bus
The system incorporates a high-performance 32-bit EISA
bus with full bus-mastering capability. Advantages of EISA
are:
■
EISA’s 33-MB per second burst mode data transfer rate
increases the speed of I/O operations which is very
important for configurations with multiple storage
devices.
■
EISA’s bus-mastering capability allows maximum sys-
tem throughput by distributing the workload to intelli-
gent subsystems. This creates balanced system
performance where no one subsystem impedes the
activity of another.
■
EISA boards are software configurable, unlike ISA
boards which require jumper settings, switch settings,
and configuration files.
■
EISA fully supports downward compatibility with
installed ISA hardware.
The EISA bus is linked to the PCI bus through the
PCI/EISA Bridge Component link and EISA System Com-
ponent link. The links allow concurrent operation.
