I think it makes sense to check for "RamSizeOver4G > 60GB" then. On q35 machine type this will actually be 62GB RAM + 2GB mmio window (below 4G), on pc machine type this will indeed be 63GB RAM + 1GB mmio window. > I have a patch series that implements the above if you're interested... Series? I'd expect a single one-line patch updating the checks, but sure, send it along. take care, Gerd _______________________________________________ SeaBIOS mailing list -- seabios@seabios.org To unsubscribe send an email to seabios-le...@seabios.org
