Ciao popolosi,
in seguito alla domanda di ax mi sono attivato e vi mando un ciappo che
legge il CMOS.
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <sys/io.h>
int
main (int argc, char **argv)
{
int i;
char cmos_content[128];
memset(cmos_content,0,128);
/* Enable CMOS access */
if (ioperm(0x70,128,1)) {
perror("This program requires root privileges.\n");
return(1);
}
/* Read CMOS memory*/
fprintf(stderr,"Reading CMOS Memory area...\t");
for (i=0;i<128;i++){
outb(i,0x70);
cmos_content[i]=inb(0x71);
}
fprintf(stderr,"...done\n");
/* Output */
write(1,cmos_content,128);
return(0);
}
Saluti,
Chris.
