Chapter 2: 7401-4xxx Product Overview 2-15
Flash Disk Interface (Discontinued)
The 7401‐45xx processor board provides support for a flash disk array
in the form of an M‐Systems DiskOnChip. A 32‐pin socket is provided
for this feature. The flash disk must be installed and enabled in BIOS
Setup. This feature is not available on the 7401‐46xx processor boards.
NCR Retail Specific Hardware
The 7401‐4xxx Processor Board contains logic that provides support for
the custom retail interface. The logic controls the following features:
• Magnetic Stripe Reader Interface
• Motion Detector
• Touch Screen Interface
MSR
The MSR interface supports a maximum of 3 tracks of magnetic stripe
information for support of ISO 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.
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 will be turned ʺonʺ anytime all power to the Processor Board is
good. The systemʹs power management software has the option to turn
the LED off indicating the system is in a power‐managed mode.
