This seems a little low: virtio block devices need I think 64 bytes at the moment. To have 32 of these behind a bridge we'll need to allocate 2K of io memory per bridge. this means we can have at most 31 such bridges but that seems a reasonable limitation to me. -- MST _______________________________________________ SeaBIOS mailing list [email protected] http://www.seabios.org/mailman/listinfo/seabios
