Pci Slots - MSI ATX BX13 User Manual

There are 5 PCI slots and 2 ISA slots. All PCI slots can be used as master.
But since the 1st and 5th PCI slots share the same bus master signal, only
one of these slots can be used as a master at a time; which means that if a
master card is installed in PCI slot 1, PCI Slot 5 can only accomodate a slave
card, and vice versa.
NOTE: 1. If on-board Creative sound is not installed, then all 5 PCI slots
can use Bus Master cards.
2. If on-board Creative sound is installed, then PCI slots 2, 3 and
4 can still use Bus Master cards. However, only one of PCI
slots 1 and 5 can use a Bus Master card at a time.
