Hi, My motherboard comes with a Intel GMA 3100 Card which shows OpenGL 1.4.5 Version and also includes a support for VBO. As per my knowledge, Only 1.5 Specification has the support for this extension. 1.4 only supported GL_NV_vertex_array_range propietary nvidia, Considered to be the fastest way to transfer vertex arrays. Is intel violating 1.5 specification? "I developed a VBO application which works fine with GMA card."

The ARB_vertex_buffer_object extension is written against the 1.4 spec. It doesn't require anything from 1.5. See the extension spec.

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
