Finally here is the solution!!!
Thanks very much to Robert Van Der Aker!!!
Most people need to manage partitions during the intallation of e-smith server (i needed it to save the compaq diagnostic partition on my Proliant DL380 servers and on an HP netserver 2000).... the steeps are easy but it is hard to find documentation!!
1) make a boot floppy with rawrite.exe (you can find it under "dosutils" directory on the cdrom) from the file boot.img (it is under the dir "image").
2) delete ks.cfg on the floppy.
3) copy the file install.cfg from images/kickstart on the floppy
4) rename it in ks.cfg
5) delete from this file all the strings regarding partitions and lilo (like that):
----------------------
# partitioning parameters
zerombr yes
clearpart --all
part /boot --size 10
part / --size 1 --grow
part swap --size 256
# boot loader
lilo --location mbr --linear
-----------------------
6) boot your server with this floppy and good luck!!!!
the result is a normal text installation that give you the possibility to partition the
disk how do you want!!!
bye!!!
