      config LARGE_ALLOCS bool Allow allocating large blocks (> 1MB) of memory help Allow the slab memory allocator to keep chains for very large memory sizes - up to 32MB. You may need this if your system has a lot of RAM, and you need to able to allocate very large contiguous chunks. If unsure, say N.





Bus options (PCI, PCMCIA, EISA, MCA, ISA)Edit

config PCI
bool PCI support
help
Support for PCI bus.
