* Constants which control the way the VM system deals with memory segments.
* Most mac68k systems have only 1 physical memory segment, but some have 2.
*
* On the systems that have multiple segments, specifically the IIsi and
* IIci, the optimal configuration is to put the higher-density SIMMs in
* bank B. This is because the on-board video uses main memory in bank A
* for the framebuffer, and a memory controller prevents access during
* video refresh cycles. Even if both banks contain the same amount of
* RAM, a minimum of ~320KB will be subtracted from the amount in bank A
* for the framebuffer (if on-board video is in use).
