F256K DIP switches
The following might be slightly outdated.

Source: https://github.com/ghackwrench/F256_MicroKernel/tree/master/docs#dip-switches
- Enable boot-from-RAM AND don't prioritize the cart to autoboot a kernel compatible KUP header program
- Reserved (potentially for SNES gamepad support)
- Enable SLIP based networking
- Feather board installed (eg Huzzah 8266 WiFi)
- SIDs are installed
- F256: CBM keyboard installed; F256k: reduced TCP window size.
- ON: 640x480, OFF: 640x400 (not yet implemented)
- Enable gamma color correction
When boot-from-RAM is enabled, the kernel will search the first 48k of RAM for pre-loaded programs before starting the first program on the expansion cartridge or the first program in flash.
