Overview
The MegaPro motherboard features are:
supports two Intel Pentium Pro CPUs operating at 133, 150, 166,
180, or 200 MHz,
supports up to 512 MB of system memory,
server management,
onboard PCI VGA,
parity checking or ECC
PCI local bus throughput of 132 MBs,
four ISA expansion slots, and
four PCI expansion slots.
ISA DMA or Bus Masters
The MegaPro Pentium Pro PCI ISA motherboard conforms to the PCI
Version 2.1 specification, if the PCI 2.1 Compliance option in Chipset
Setup is set to Enabled. The Version 2.1 PCI specification requires a
deterministic latency for PCI devices. Computers that use ISA DMA or
ISA bus masters will experience longer access latencies if the PCI 2.1
Compliance Chipset Setup option is set to Enabled. AMIBIOS
automatically configures the PCI slots. The PCI slots are synchronous
with the CPU clock:
CPU External Clock Frequency
66 MHz
60 MHz
Onboard I/O
The MegaPro motherboard includes:
two 40–pin IDE connectors for 1 – 4 IDE drives,
a 34–pin floppy drive connector,
two serial port connectors,
a 25–pin parallel port connector,
a VGA connector,
a keyboard DIN connector, and
a 9–pin berg mouse connector.
