I will take the disks and move them to a spare pentiumI so I can keep working meanwhile. The problem is I need to have a kernel that will work with a different processor and with a different ethernet card. My question: are there any issues in having two different kernels and booting from the alternatively? I mean switching kernels before booting so I don't have to 'unload' a kernel at boot time and then load a diffent one. And: should I backup both the kernel and the kernel modules under a different name (kernel.p3, modules.p3/) so I can then boot from it later? Thanks in advance, Fernan PS: please CC me since I'm not subscribed to the list -- F e r n a n A g u e r o http://genoma.unsam.edu.ar/~fernan
