this seems to work on a 64-bit-system:
main(int argc, char *argv)
unsigned char b;
if (iopl(3) == -1)
b = inb(0xec00);
It is c, but now I simply need to know how to call c functions in pascal
programs. I am using a linux kernel in version 2.6.28, and for this
kernel version your quotation of "man iopl" seems not to be valid.
