The SXCE DVD doesn't contain the amd64 kernel in its miniroot boot archive. Therefore the IA32 kernel gets booted by default, rather than autodetection of amd64 if supported, else IA32 (like when you boot from hdd). Also: I personally don't understand why Sun made that design decision back in 1997/98 to treat a booted 32bit kernel and booted 64bit kernel as the same platform, and hence to identify it with the same uname() field values. In this case I prefer how linux handles it. Of course it is trivial to depend on isainfo for configure scripts or automated choice of Makefiles, but this stuff belongs into different platforms and correspondingly into separate uname() fields. But I don't want to start a fight. _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
