Re: [Xense-devel] [Q] about ACM/IA64 status

[Atsushi SAKAI <sakaia@xxxxxxxxxxxxxx>]

Hello　Reiner

　I survey the possibility of implementing ACM to IA64.
The problem is that
the current ACM uses grub/multiboot specification.
(IA64 uses elilo at this moment. not grub)
To correctly implment ACM, we need to add multiboot specification to elilo.
Regrettably I have not enough time to implement the multiboot at this moment.

Thanks,
Atsushi SAKAI
