Ok George!
Basically I agree with you!
However, Iain Shigeoka is planning to prepare a "bundle" including a boot
loader. If everyone agrees in using GRUB, I'll stop my work and I'll start to
implement something else for JOS (what can I do ? Any suggestions ?).
Concering Botch booting, I have successfully booted JOS only in text-mode. Check
the suggestions on my previous e-mail. Probably, your boot process is OK. Some
error messages are NOT real error messages (check the init.java source!).
... I'm waiting for your answers men!
Bye,
Corrado
