Thanks Eddi Torres and Abe, I gare; finally the Voodoo3 30000 has acceleration. I have tryed before to do that using linux.3dfx.com page, but I forced the installation of Glide (the version in this page is older than the present Mandrake 7.2) and then the X system crashed. Chmoulin said me that it could be a problem with the motherboard chip i850e!!! and that I had to wait for new kernels, so I didn't try any other installation. But after read your messages I tryed again; this time I didn't user the Glide reinstallation, I just used: rpm -Uvh tdfx_dri-4.0.1-1.¡386.rpm rpm --rebuild tdfx_drm-1.0-3.src.rpm rpm -Uvh --force /usr/src/RPM/RPMS/i686/tdfx_drm-1.0-3.i686.rpm The option --force was absolutly necessary. And it works!!!! Quake 3, Chromium and so one (quake 3 in fact is too speedee, impossible to survive!!!!). It seems that the mandrake 7.2 has a bug about the installtion of 3d acceleration, in fact, one message talked about somekind fo lint between Voodoo3 and AGP (Abe, you were true when you said that 3dfx carss are not real AGP cards, but PCI cards using the advantages of AGP slot. In fact Harddrake said that my voodoo is a PCI card!!! I hope this problem will be solved in future Mandrake releases; in fact most potential home linux user like games using 3d acceleration, this will be a good base to attract people from windoze!! Thanks a lot and let me have fun playing for a while!!! Francisco Alcaraz Murcia (Spain)
