ServerWorks ® Grand Champion LE north bridge (CMIC-LE).
The Champion Memory and I/O Controller LE (CMIC-LE) acts as
the host bridge of the Grand Champion Low End (GCLE)
SystemSet. The CMIC-LE device interfaces directly to the
processor bus, and integrates the functions of the main memory
controller and the Inter Module Bus (IMB) interface unit. The
processor interface supports a 533/400MHz Front Side Bus (FSB)
providing a 4.26GB/s or 3.2GB/s bandwidth, 2-way interleaved
memory up to 12GB using registered ECC PC2100/1600 DDR
DIMMs, and two high speed IMBs plus one thin IMB to connect to
the south bridge CSB5.
DIP switches. This 5-switch Dual Inline Package (DIP) allows you
to set the CPU external frequency.
603/604-pin CPU sockets. Two 603/604-pin surface mount, Zero
Insertion Force (ZIF) sockets for the Intel
® Xeon™ processor with
512KB L2 cache and a 533/400 MHz system bus that allows up to
4.26GB/s or 3.2GB/s data transfer rate.
IDE connectors. These dual-channel bus master IDE connectors
support up to four Ultra DMA/100/66, PIO Modes 3 & 4 IDE
devices. Both the primary (blue) and secondary (black) connectors
are slotted to prevent incorrect insertion of the IDE ribbon cable.

South Bridge (CSB5) primarily acts as a PCI to Low Pin Count
(LPC) bridge, but also supports several integrated functions
including dual-channel ATA/100 IDE controller, 4-port USB 1.1
interface, ACPI power management and detection, XIO-APIC, and
legacy functions 8237DMA, 8259APIC, and 8254 timer.
