Hi, Quoting the memdisk.doc: Similarly, if you're booting DOS over the network using PXELINUX, you can use the "keeppxe" option and use the generic PXE (UNDI) NDIS network driver, which is part of the PROBOOT.EXE distribution from Intel: Does anyone know what this means? It sounds like a generic network driver for DOS exists. I have a copy of the PROBOOT.EXE, but I can't work it out. If this is what I think it is, has anyone made it go or even better, made a version that works with Bart's ModBoot network disk? (www.nu2.nu/bootdisk) Thanks in advance, Jack Kelly
