American Megatrends MAN-772 manual Chipset

Overview, Continued

Chipset	The Apollo IV PCI Pentium ISA baby-AT size motherboard uses an Intel
	430TX chipset, including CPU interface controller, advanced cache
	controller, integrated DRAM controller, synchronous ISA bus controller, PCI
	local bus interface, and an integrated power management unit. The Intel
	430TX chipset supports intelligent diagnostic and power management
	through features such as DMI support.

Expansion Slots The motherboard includes:

∙three 16-bit ISA expansion slots and

∙four 32-bit PCI expansion slots.

The PCI local bus throughput can be up to 132 megabytes per second.

L1 Internal Cache The Intel Pentium on the motherboard has an 8 KB data cache and an 8 KB instruction cache.

L2 Secondary Cache The motherboard has 512 KB of pipeline burst direct-mapped, WriteBack L2 secondary cache memory. Up to 256 MB of system memory can be cached.

Supported Standards The Apollo IV motherboard supports:

∙DMI,

∙the Intel DPMA (Dynamic Power Management Architecture,

∙Concurrent PCI V2.0 and V2.1, and

∙USB (Universal Serial Bus).

Switching Voltage Regulator This motherboard includes a switching voltage regulator that significantly reduces the CPU and voltage regulator temperature. This voltage regulator is also fully upgradable to the next generation of Socket 7 CPUs. These new CPUs will require more electrical current and will generate more heat.
