Booting to Boot Block Flash with Fail Safe Boot ROM

Note Boards are shipped with Fail Safe Boot ROM enabled. When Fail Safe Boot ROM is enabled, the system will boot to it exclusively.

The Fail Safe Boot ROM is a minimal build of ROM-DOS™ located inside a surface-mounted Boot Block Flash chip. Boot Block Flash is a write-protected flash device that contains the BIOS and extra room where the Fail Safe Boot ROM is stored. Additionally, Fail Safe Boot ROM is an emergency interface accessible by an external computer. The ROM DISK contains utilities for remote access to the system’s disk drives. Due to the size of the flash chip, Fail Safe Boot ROM contains an abbreviated selection of the ROM-DOS™ utilities; however, the complete ROM-DOS™ is contained on a CD shipped with the cpuModule.

The purpose of the Fail Safe Boot ROM is to make the cpuModule bootable upon receipt. The Fail Safe Boot ROM can be used as an indicator of the module’s functionality when booting problems arise with another operating system. This test can be accomplished by enabling the Fail Safe Boot ROM in the Boot section of the BIOS Setup Utility. Enabling this option forces the cpuModule to boot to Fail Safe Boot ROM.

To boot to the Fail Safe Boot ROM, install jumper JP5, and apply power to the system.

Note If power is applied to the system while JP5 is installed, the multi-color LED will turn red.
