One of the P0 ports may instead be switched to the Expansion Site
connector, making it available on the front panel via the XBRD-9060
I/O Expander module.

The APTIO
Haswell Core BIOS Manual For Acromag Products.
3.11 Battery Powered Real Time Clock (RTC)
A Motorola
®
MS146818B‐compatible real‐time clock
(RTC) is included in the
Intel® Lynx Point PCH. The RTC has 256 bytes of battery‐backed RAM and
runs on a 32.768 KHz crystal with a 3V battery. The RTC performs two key
functions:
•
It keeps track of the time of day, and
•
It stores system data, even after powering down the system.
To clear the RTC and CMOS RAM settings, remove battery BT1 from the
socket for 10 seconds and reinstall.
The battery can be replaced with a standard CR1225 battery.
Note:
If the battery has been removed, the RTC voltage drops below 2.5V, or
when a BIOS update has been done, the first time the system is powered on
it may partially boot and then restart up to two times. This behavior is
normal.
3.12 Security
3.12.1 Trusted Platform Support
The XVME-6700A uses the Atmel AT97SC3204 (1.2) or Infineon SLB9665XT20
(2.0) fully integrated security module, which implements version 1.2, or 2.0,
of the Trusted Computing Group (TCG) specification for Trusted Platform
Modules (TPM). The TPM includes a cryptographic accelerator capable of
computing a 2048-bit RSA signature in 200ms and a 1024-bit RSA signature in
40ms. Performance of the SHA-
1 accelerator is 20μs per 64
-byte block.
3.12.2 Password Control
You are able to specify:
•
An Administrator password with full control, and
•
A User password with limited access to the BIOS settings.
For further information on setting the password, refer to
The APTIO Haswell
Core BIOS Manual For Acromag Products.
