Board Bios - NCR 7454 Hardware User's Manual

Chapter 1: Product Overview 1-19
Power LED
The Processor Board provides support for an external power LED
through the onboard Motion/Power LED connector. This LED is
controlled through the SMC 37C935 GPIO pins. Once the SMC chip is
programmed to support the Power LED function on GPIO pin 13, the
LED is turned "on" anytime all power to the Processor Board is good.
The system's power management software has the option to turn the
LED off indicating the system is in a power‐managed mode.
MSR
The MSR interface supports a maximum of 3 tracks of magnetic stripe
information for support of ISO or JIS format cards. Activate the MSR
interface by enabling it in BIOS Setup under IO Configuration. The
MSR interface controller is a memory‐mapped device, which can reside
at system memory addresses CA000, CC000, or D0000. If MSR
capability is not desired, it may be disabled through BIOS Setup.

Board BIOS

The Processor Board uses a Phoenix BIOS, which is stored in Flash
ROM and easily upgraded through the network connection or serial
port. The Flash EEPROM also contains the Setup utility, Power‐On Self
Tests (POST), and APM 1.2. The board also supports system BIOS
shadowing, which enables the BIOS to execute from onboard write‐
protected DRAM.
The BIOS displays a sign‐on message during POST identifying the type
of BIOS and a five‐digit revision code.
