Memory Translator Hub (MTH)
The Memory Translator Hub allows the PIIISCA/PIIISCD/370SC3/370SCI/
370SCD to support DIMM (SDRAM) type memory. Note for the PIIISCA:
Only one type of memory can be used; if RIMM(s) are installed, then any
installed DIMM(s) will be disabled. The MTH does not support ECC; using
ECC memory will result in non-ECC operation. See page 3-3 for details.
Audio Modem Riser (AMR)
The AMR is a modular specification that integrates the audio/modem func-
tions on the motherboard by assigning the analog I/O functions to a riser
card. Integration of the audio/modem function enhances system capabilities
while reducing costs.
compliant with Intel's Audio Codec '97 version 2.1 specification.
Firmware Hub (FWH)
The FWH is a component that brings added security and managability to the
PC platform infrastructure. This device includes an integrated Random Num-
ber Generator (RNG) to enable stronger encryption, digital signing and se-
curity protocols. The FWH provides storage for the system BIOS and video
BIOS, which eliminates a redundant nonvolatile memory component.
Suspend to RAM (STR)
When the system goes into a deep sleep (S3) state, power is removed from
most of the system components but remains supplied to RAM to quickly
restore the system to its previous state of operation.
restoral happens in only ~5 seconds, applications that were open before
the sleep state can reopen for immediate access. In STR, all data in system
memory is stored in RAM when the system is suspended and system power
is turned off (the power supply fan also shuts off).
ACPI for this feature to take effect. See page 1-28 for details on initiating
ACPI. All drivers and add-on cards must be ACPI supported for STR to
function.
Recovery from AC Power Loss
BIOS provides a setting for you to determine how the system will respond
when AC power is lost and then restored to the system. You can choose
for the system to remain powered off (in which case you must hit the
