[FUGSPBR] New cdboot ISO available (fwd)

[Edson Brandi]

Boa tarde

Apenas a titulo de informação acabei de testar agora o novo sistema de
boot em 4 maquinas e funcionou muito bem ... desde um arcaico Pentiu Pro
200, ate a minha maquina mais nova que roda com um Pentium III 800

Acho que o novo sistema vai emplacar :-)
