Dear all:
Thanks for Valery's help , but it has some trouble for roottask
loading module.
the following is the command for roottask in my menu.lst
==============
module /common/roottask -symbols -lines task modname "loader"
boot_priority 0xA0 allow_cli task modname "bmodfs" attached 5 modules
==============
and this is the command for bmodfs
==============
module /common/bmodfs
module /common/cfg/l4linux26.cfg
module /common/libloader.s.so
module /common/libld-l4.s.so
module /common/vmlinuz
module /common/drops.rd
==============
the following is the loader script for L4linux
======l4linux26.cfg========
#l4linux cfg
verbose 0
sleep 1
task "vmlinuz" "mem=64M load_ramdisk=1 ramdisk_size=16384
root=/dev/ram l4env_rd=drops.rd"
allow_cli
priority 0xA0
all_sects_writable
allow_vga
======l4linux26.cfg========
And this is the error message
==============
Roottask: Loading 11 modules.

==============
When I followed the step that adding "allow cli" this feature, it has
trouble for registering some module to nameserver.
Can someone give me some advice how to solve this problem?
Thanks!!
Best Regards.
