Manufacturer DKB, USA | Date 1988 | Amiga A1000 | Interface 68000 socket |
- Kickstart switcher
- eliminates the need for disk-based Kickstart and so makes the A1000 boot faster
- one socket with Kickstart 1.2 or 1.3 installed
- can be switched back to Kickstart disk based operation with a jumper for pre-1.3 software compatibility
- pressing Control Amiga Amiga for more than three seconds will also revert to disk based Kickstart
- frees up the 256 kB Kickstart RAM
- connects to the 68000 socket
- the PAL at location 6J of the WCS daughterboard has to be replaced with the supplied PAL
- can be installed together with the DKB Insider - KwikStart has to be at the bottom, Insider on top of it

Manufacturer DKB, USA | Date 1990 | Amiga A1000 | Interface 68000 socket |
- Kickstart switcher
- eliminates the need for disk-based Kickstart and so makes the A1000 boot faster
- two sockets allow both 1.3 and 2.0 ROMs installed at once
- can switch between ROMs using the keyboard without shutting off the computer
- if only one ROM is installed, the A1000 can be switched back to disk-based operation for pre-1.3 software compatibility
- connects to the 68000 socket
- installation involves the replacement of a soldered PAL chip (6J on the daughterboard)
- does not allow using the freed up 256 kB Kickstart RAM - the larger Kickstart 2.0 uses that address space

Manufacturer DKB, USA | Date 1991 | Amiga A500, A2000 | Interface Kickstart socket |
- Kickstart switcher
- two sockets for Kickstart 1.2 - 3.1 ROMs - uses standard Amiga Kickstart ROM chips
- can be used with one or two ROMs installed
- switches between ROMs using the keyboard
- the ROM to be used on power up can be selected with a jumper
- a jumper wire has to be attached to pin 41 of Gary
- three variants:
- two 40 pin Kickstart sockets and a 40 pin header - a ribbon cable connects the header with the motherboard Kickstart socket
- three Kickstart sockets - a ribbon cable connects the third socket with the motherboard Kickstart socket
- three Kickstart sockets - the third has long legs on the bottom of the MultiStart which fit directly into the motherboard Kickstart socket

- password protection
- once installed, the board requires the user to enter a password at warm or cold boot
- three chances are given and if they all fail, the machine is locked, requiring a cold reboot
- on softkicking A3000s the password has to be entered twice: before Kickstart is loaded, and after the warm boot
- passwords are case sensitive and not displayed on the screen when typing
- the protection can be bypassed by removing the card
