------- Additional Comments From mike@codeweavers.com 2006-11-06 20:58 ------- We already have problems with applications running out of memory because we only have 2G to play with, though admittedly those problems are also due to address space fragmentation.
I think even if we moved wine-preloader, the 2G/2G split may still incompatible with the win32 address space, because there are things that need to be mapped above 78000000... but perhaps the majority of applications will not be affected by this.
You can try change the preloader mapping address. It is defined in loader/Makefile.in. If that works, submit a patch to wine-patches and argue for the change there.
