I finally managed to make tomsrtbt-1.7.361 working on my 2.4.17 kernel
this is a first step before starting a bigger system.

- First i used http://cbothamy.free.fr/projects/plex86/ patches. [ and 
rombios.bin ]
- Second i took care of configuration commands order :
- defined vales boch-opts before any pluggins ( and removed bochs-init )
- Third i load all possible pluggins

[ in this configuration hard disk is not really used, but mk2fs it and mounted 
it then hd system is working ]

Here an example of my conf :
