Betreff: [PATCH] ppc/pegasos2: Change default CPU to 7457
Previously 7400 was selected as a safe choice as that is used by other
machines so it's better tested but AmigaOS does not know this CPU and
disables some features when running on it. The real hardware has
7447/7457 G4 CPU so change the default to match that now that it was
confirmed to work better with AmigaOS.
Can't we also increase the memory "mc->default_ram_size = 512 * MiB;" to 1024
for default settings ?
Long term tests have confirmed that it works very well with 1024 MB memory
under AmigaOs4.1.
No, the default memory size is not the largest possible but something sane
that works bur won't eat all the memory of the host. Nowadays it's less of
an issue but the default for most machines are still 128MB which I've
already increased to 512MB for these machines as this is a better value
for Amiga like OSes running on these machines but larger default may be
too much. Adding a -memory option is less confusing then picking the right
CPU type so requiring that for more memory is less of a problem.
