I am not using a multiboot disk. I had a previous working install disk with only the mass storage, LAN and chipset drivers. I updated it with ALL of the drivers and burnt it to a DVD instead of a CD. I also use RyanVM hotfixes, but they have not been updated on this occasion. Any ideas why I am getting this strange error, aliide,sys not found? Would it be helpful if I uploaded my winnt.sif and dosnet files? Cheers. Jeremy
