thanks for the example.
but maybe because it's monday morning ;) i didn't understand well the 
way to use the bmodfs server. i've been able to boot with tftp but where 
i'm going to place this in use i don't have tftp availability.
i've done the following menu.lst entry

title        Fiasco Linux L4Env
root        (hd0,0)
kernel        /home/tiago/fiasco_builddir/rmgr -sigma0 task modname "bmodfs"
modaddr        0x02000000
module        /home/tiago/fiasco_builddir/main -nokdb -nowait 
-serial_esc -comspeed 115200 -comport 1
module        /home/tiago/fiasco_builddir/sigma0
module        /home/tiago/fiasco_builddir/names
module        /home/tiago/fiasco_builddir/log
module        /home/tiago/fiasco_builddir/dm_phys
module        /home/tiago/fiasco_builddir/simple_ts -t 300
module        /home/tiago/fiasco_builddir/rtc
module        /home/tiago/fiasco_builddir/l4io --noirq
module        /home/tiago/fiasco_builddir/bmodfs
  module        /home/tiago/fiasco_builddir/libloader.s.so
  module        /home/tiago/fiasco_builddir/loadercfg
  module        /home/tiago/fiasco_builddir/vmlinuz.l4env
module        /home/tiago/fiasco_builddir/l4exec
module        /home/tiago/fiasco_builddir/loader --fprov=BMODFS 
/home/tiago/fiasco_builddir/loadercfg

what am i doing wrong?
btw, the libloader.s.so it's giving the error that it's accessing the 
position 0x0000000 of memory. am i loading it correctly?

now it's more a technical question.
if i use l4io with that option, who will manage the irqs? will it be 
l4linux with l4irqack=linux option on? how the information will reach 
the l4io server so it can go into other server that use l4io?

thanks
