The Direction SP E-Series supports ISA Plug and Play
expansion boards, which allow you to install a board in an
expansion slot without changing the hardware settings.
There are no system resource conflicts to resolve. Plug and
Play automatically configures the board for the system.
Industry-standard 8-bit and 16-bit ISA, and 32-bit PCI
expansion boards are supported in the system unit. ISA
expansion boards can be Plug and Play or non-Plug and
Play boards.
PCI expansion boards run at one half the system host's bus
speed. The PCI bus handles 32 bits of data at a time, being
wider as well as faster than the standard ISA bus. PCI
boards can send and receive data much faster, thereby
boosting system performance.
Your system has three expansion slots:
T
one ISA slot
T
two PCI slots.
The option board slot configuration accommodates the
following devices:
NOTE
The four furthest-left slots (as seen from the
front) on the desktop model or four lowest slots on
the minitower are not used.
T
Slot 1 — Accommodates an optional PCI board.
