You could try to free some space by removing all comments from AmiTCP's config files.
You could also try to pack AmiTCP and other big executables with PowerPacker or a similar load module packer.
And you will gain about 50KB if you format the disk with FFS rather than OFS.
You don't need LoadMonDrvs if it does not work anyway. Remove it's call from Startup-Sequemce and delete it from C:.
