-nomap

OFP Command line switch -nomap forces OFP to avoid memory mapping for file access. While memory mapping is very efficient from performance point of view, it can quickly fill all available virtual space, causing various memory allocation error or even driver crashes or freezes.

This switch is especialy important for users with display adapters with large ammounts of VRAM (128MB or more), which reserve a lot of virtual address in the application address space for themselves.
