Installing via serial line trouble

[Grigory Batalov <bga@kgok.murmansk.su>]

  I try to install Debian 2.2r4 to HP Omnibook 4000CT.
It has 486/100MHz-processor, 16Mb of memory, floppy,
no CD-ROM and no ethernet card.
  I hope to install via serial line and NFS
(or ftp/or something). And save previous installation
of Win'95 to other computer.
  Is it possible?

First of all I've installed Debian on my home machine
under VMWare and made changes to root floppy image:

/lib/modules/2.2.19/
    /fs/
       lockd.o
       nfs.o
       nls_cp866.o
       vfat.o
    /misc/
       sunrpc.o
    /net/
       slhc.o
       slip.o
/sbin/
     slattach

Then I said 'chroot /image-dir depmod -a', packed
and copied image back to floppy.

Now when I boot from rescue and this root disks,
I switch to second console and do the folowing:

ifconfig lo 127.0.0.1
route add -host 127.0.0.1 lo
modprobe slip
slattach -s 115200 -p slip ttyS0 &
ifconfig sl0 192.168.84.2 pointopoint 192.168.84.1 up
modprobe nfs
mkdir /mnt/nfs
mount -t nfs 192.168.84.1:/pub /mnt/nfs

And have this:
Mounting 192.168.84.1:/pub on /mnt/nfs failed: Invalid argument

------------------------------------------------
 By this point I have same sl0 interface on host
machine with IP 192.168.84.1 and can ping it.
 NFS server is running and reachable from VMWare
by same 'mount -t nfs 192.168.84.1:/pub /mnt/nfs'
command.

On laptop:

-------------------------------------------------

  Ok. So where I was wrong? Maybe I should use
ftp or other way? I'm novice to Debian but have
some experience in one Mandrake-based distribution.

  All comments are welcome. Please, help me.
