Problem of running L4Linux

[Adam Chang]

Dear all:
Thanks for Adam's advice. but there still has some problem.
the following is my new menu.lst

=====Begin of menu.lst=========
default=0
timeout=0
splashimage=/boot/grub/splash.xpm.gz
hiddenmenu
title L4Linux-2.6
kernel /common/bootstrap
modaddr 0x02000000
module /common/fiasco -nokdb -serial_esc
module /common/sigma0
module /common/roottask -symbols -lines task modname "loader"
boot_priority 0xA0 allow_cli task modname "bmodfs" attached 7 modules
module /common/Lines
module /common/Symbols
module /common/names
module /common/log
module /common/dm_phys --isa=0x00800000
module /common/simple_ts -t 300
module /common/rtc
module /common/l4io
module /common/l4dope
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
 module /common/proxygon
 module /common/run
module /common/loader --fprov=BMODFS proxygon run l4linux26.cfg
vbeset 0x117
=====End of menu.lst=========

And the following is the loader script for L4linux

=====Begin of l4linux26.cfg=========
#l4linux cfg

  verbose 0
  sleep 1
  task "vmlinuz" "mem=64M video=l4fb:refreshsleep:200 load_ramdisk=1
ramdisk_size=16384 root=/dev/ram l4env_rd=drops.rd"
    allow_cli
    priority 0xA0
    all_sects_writable
    allow_vga

=====End of l4linux26.cfg=========

It still black screen forever for using l4con. And for using Dope I
can see the graphic environment and the console titled "proxygon",
but when I clicked the windows and press L key, then the Vmware
machine rebooted. sometimes the cursor can't be moved through my
mouse. sometimes I saw only the background without console.It confused
me.
So the above is my current circumstance，can someone give me some
advice how to solve this problem?
Thanks!!

Best Regards.
