It is meaningless. (Maybe there was some meaning long ago, for example because HDIO_GETGEO only uses a 16-bit field for #cyls. These days bios_cyl is not used anywhere. Not in the kernel, not in user space. It is just some random number, computed by taking disk-size / (heads*secs).) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
