IS THIS FROM ULTRIX ?????? ^^^^^^ We ask to our DEC representants and just said tha we must change our version to ULTRIX 3.1, then we receive the upgrade, but it doesn't works (a sintax error when compiling the new Kernel, so we can't build the new Kernel), the problem is in the gfs_data.c archive, we told them and just send us a new copy of it that doesn't works either. Help me please......!!!! Thanks ! Atte. Jose A. Vela Avila. josevela@mtecv2.mty.itesm.mx
