Thanks scarecrow!
I tried Md2009one but doesn't boot, all distros with kernel 2.6. doesn't boot (Mandriva one, Arch, TinyMe)
I tried puppy too but it doesn't recognize my PCMCIA so I cannot networking. I'm still searching to bring up the interface
I tried DSL but when I installed on HDD it destroyed my MBR so I have to reinstall Win and everything. This distro lacks in living with other OS on HDD.
Finally Mdk9.2 was a reasonable choice.
Now I have on my box Win98SE, Mdk9.2, Puppy4.2.1, FreeBSD7.2, but just for Win and Mdk I could bring up the network. For the others I'm still searching. After finding a solution I can compare them in term of speed and everything
