Forgot these...
/* Constants to setup and access the VIC. */
#define ringCLEAR_VIC_INTERRUPT	( ( unsigned portLONG ) 0 )
#define RING_VIC_CHANNEL	( ( unsigned portLONG ) 0x0E )
#define RING_VIC_CHANNEL_BIT	( ( unsigned portLONG ) 0x4000 )
#define RING_VIC_ENABLE		( ( unsigned portLONG ) 0x20 )
#define EINT0_ENABLE		( ( unsigned portLONG ) 0x01 )
#define ringCLEAR_VIC_INTERRUPT	( ( unsigned portLONG ) 0 )

Corrected the function name, is vRING_ISR and nothing else!

Thanks in advance..
