Address Map
In the Addr field, letters have the following meaning:
• "x...x": match any value
• "aaaa": match if equal to IOMMEN cfg_base field
• "bbbbb": match if equal to IOMMEN sca_clump field
• "ccc": match if corresponding IOMMEN sca_ena bit is set
• "dddd": match if greater than IOMMEN cfg_base and Addr[31] = 0
• "eeee": match if greater than IOMMEN cfg_base and Addr[31] = 1; prevent match
• "aaaa": match if equal to IOMMEN cfg_base field
• "bbbbb": match if equal to IOMMEN sca_clump field
• "ccc": match if corresponding IOMMEN sca_ena bit is set
• "dddd": match if greater than IOMMEN cfg_base and Addr[31] = 0
• "eeee": match if greater than IOMMEN cfg_base and Addr[31] = 1; prevent match
when Addr[31:26] = 111111
• "ffff": match if the BIOSEN r/w enable bit is set for the corresponding segment, for
reads and writes, respectively
• "*" means that Addr[43:32] = 0x000 always matches, and Addr[43:32] = 0xFF0
matches in SMM mode
• "+" means that the address is in the I/O address space, separate from the memory
address space
Target lists are needed for the CFG, MMIOL0/1, CPU/IOH Cfg, IOAPIC, FWH, and
Legacy I/O regions. These entries make up the I/O Large (IOL) Decoder. The reasons
for the existence of target lists for these regions are described in the following table.

Trusted Execution Technology (Intel
®
TXT)
Intel
®
Trusted Execution Technology (Intel
®
TXT) is a component of the Intel
®
Safer
Computing Initiative (Intel
®
SCI). Intel
®
TXT was first introduced in client platforms.
Intel TXT for Servers is an effort to extend Intel
®
TXT into server platforms. Intel
®
TXT
for Servers is a software binary compatible with Intel
®
TXT and uses a security model
that allows the RAS features to co-exist with security. To achieve this objective, some
of the system firmware is allowed to be within the trust boundary.

Intel

TXT provides an architected process to measure the BIOS and measured launch
environment (for example, VMM or OS) before launch.
3.2.1
Key Concepts
• Intel
®
TXT is a family of security capabilities now available on server platforms.
• Intel
®
TXT uses features in the processors, chipset, BIOS, and TPM to enable more
secure platforms.
• Intel
®
TXT works through measurement, dynamic launch mechanisms via special
instructions, memory locking and sealing secrets.
• Intel
®
TXT helps detect and/or prevent software attacks.
