Technical Product Specification

Product Architecture Overview Intel® Server Board S1600JP TPS
3.4.9
Advanced Programmable Interrupt Controller (APIC)
In addition to the standard ISA compatible Programmable Interrupt Controller (PIC) described in
the previous section, the Intel
®
C600 PCH incorporates the Advanced Programmable Interrupt
Controller (APIC).
3.4.10
Real Time Clock (RTC)
The Intel
®
C600 PCH contains a Motorola* MC146818B-compatible real-time clock with 256
bytes of battery-backed RAM. The real-time clock performs two key functions: keeping track of
the time of day and storing system data, even when the system is powered down. The RTC
operates on a 32.768 KHz crystal and a 3V battery. The RTC also supports two lockable
memory ranges. By setting bits in the configuration space, two 8-byte ranges can be locked to
read and write accesses. This prevents unauthorized reading of passwords or other system
security information. The RTC also supports a date alarm that allows for scheduling a wake up
event up to 30 days in advance, rather than just 24 hours in advance.
3.4.11
GPIO
Various general purpose inputs and outputs are provided for custom system design. The
number of inputs and outputs varies depending on the Intel
®
C600 PCH configuration.
3.4.12
Enhanced Power Management
The Intel
®
C600 PCH power management functions include enhanced clock control and various
low-power (suspend) states. A hardware-based thermal management circuit permits software-
independent entrance to low-power states. The PCH contains full support for the Advanced
Configuration and Power Interface (ACPI) Specification, Revision 4.0a.
3.4.13
Fan Speed Control
The Intel
®
C600 PCH integrates four fan speed sensors (four TACH signals) and four fan speed
controllers (three Pulse Width Modulator signals), which enables monitoring and controlling up
to four fans on the system. With the new implementation of the single-wire Simple Serial
Transport (SST) 1.0 bus and Platform Environmental Control Interface (PECI), the PCH
provides an easy way to connect to SST-based thermal sensors and access the processor
thermal data.
3.4.14
Intel
®
Virtualization Technology for Direct I/O (Intel
®
VT-d)
The Intel
®
Virtualization Technology is designed to support multiple software environments
sharing same hardware resources. Each software environment may consist of an OS and
applications. The Intel
®
Virtualization Technology can be enabled or disabled in the BIOS setup.
The default behavior is disabled.
Note: If the setup options are changed to enable or disable the Virtualization Technology setting
in the processor, the user must perform an AC power cycle for the changes to take effect.
The chipset supports DMA remapping from inbound PCI Express* memory Guest Physical
Address (GPA) to Host Physical Address (HPA). PCI devices are directly assigned to a virtual
machine leading to a robust and efficient virtualization.
