  • Page 16 There are 5 PCI slots and 3 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 bus master card is installed in PCI slot 1, PCI Slot 5 can only accomodate a slave card, and vice versa.

  • Page 17: Memory Bank Configuration

    2.3-1 Memory Bank Configuration The mainboard provides four 72-pin SIMMs (Single In-Line Memory Module) and two 168-pin DIMM(Double In-Line Memory) sockets. It supports six memory banks for a maximum of 256MB memory. Each bank supports up to 64MB memory. You can use SIMM from 4MB, 8MB, 16MB, 32MB, 64MB to 128MB, and DIMM from 8MB, 16MB, 32MB, 64MB to 128MB.
