There are a total of 256 Dipswitches that are initialized at boot (possibly from the CP box MMIO region), labeled from 0 to 255. They are gated off by console type. Retail, testkit, devkit, and intdev-flagged devkit have access to more and more dip switches respectively. Retail can access none, testkit can access a limited selection, devkits can access most, and intdev-flagged devkits can access all. Below is a list of dipswitch/boot param indexes and their descriptions.
