CP3004-SA
2.5 Flash Memor y
The CP3004-SA provides flash interfaces for the uEFI BIOS and the SATA Flash module.
2.5.1 SPI Boot Flash for uEFI BIOS
The CP3004-SA provides two 16 MB SPI boot flashes for two separate uEFI BIOS images, a standard SPI
boot flash and a recovery SPI boot flash. The fail-over mechanism for the uEFI BIOS recovery can be
controlled via the DIP switch SW1, switch 2.
Note:
The uEFI BIOS code and settings are stored in the SPI boot flashes. Changes made to the
uEFI BIOS settings are available only in the currently selected SPI boot flash. Thus, switch-
ing over to the other SPI boot flash may result in operation with different uEFI BIOS code
and settings.
2.5.2 SATA Flash Module
The CP3004-SA supports up to 32 GB flash memory as an optional SATA Flash module. The SATA Flash
module cannot be used in conjunction with the Smart Extension Module, the CP3004-HDD module or
the CP3004-XMC module.
2.6 Trusted Platform Module 1.2
The CP3004-SA supports the Trusted Platform Module (TPM) 1.2. TPM1.2 is a security chip specifically
designed to provide enhanced hardware- and software-based data and system security. It is based on
the Atmel AT97SC3204 security controller and stores sensitive data such as encryption and signature
keys, certificates, and passwords. Furthermore, it is able to withstand software attacks to protect the
stored information.
2.7 Board Inter faces
2.7.1 Front Panel LEDs
The CP3004-SA provides two system status LEDs: one temperature status LED (TH LED) and one Watch-
dog status LED (WD LED). It also provides four General Purpose/POST code LEDs (LED3..0). Their func-
tionality is described in the following sections and reflected in the registers mentioned in Chapter 3
Configuration.
