PCI
The 32-bit Intellio C218Turbo/PCI board complies with PCI Spec. 2.1. Hardware
configuration for IRQ and Memory addresses is automatically assigned by PCI
BIOS. Hence, it is a must to
have the board plugged first before installing software
driver.
Unlike ISA slots, different PCI slots in the same PC may have different bus numbers
and device numbers with respect to PCI specifications. The same PCI board will
have different system configurations if switched to a different PCI slot, which may
be called
slot-sensitive or slot-dependent. This may also apply to PCI slots in PC of
different mother board, which may use
different device number set. For example,
some use 17, 18, 19, and 20 for identifying the respective PCI slot but some use 11,
12, 13 and 14.
Due to the
slot-dependency, it is necessary to re-configure the software driver
once the board is plugged in different PCI slots.
Up to four boards of
Intellio C218Turbo/PCI are allowed in a system. When
installing multiple boards,
please do keep in mind the order you plug the boards
for distinguishing the boards installed.
Dual-Ported RAM
There is 512 KB of dual-ported DRAM on the Intellio C218Turbo/PCI, which is
used as a data buffer and memory map device for the mother board. It is called
"dual-ported" because it is accessed by both mother board CPU and the Intellio
C218
Turbo/PCI on-board CPU. Generally speaking, the memory access time is much
