PCI Slots
There are four PCI slots on board; 3 are “master” bus and one is “slave.”
133MB/s data transfer rate on PCI bus can be compared to 33MB/s on EISA
bus or 8MB/s on ISA bus. PCI interface has synchronous data transfer rate
from CPU to PCI with good graphic performance.
While plugging into 4 PCI add-on cards, PCI 1- PCI 3 are master bus and PCI4 is
slave bus. If there are 3 PCI add-on cards (or below 4 cards), all of them are master
bus.
