		+	The following is based on an AGA based A1200/A4000 Amiga. This is different for older OCS based systems.
		+
		+	The system performs the following test sequence:
		+
		+	1. Delays beginning the tests a fraction of a second to allow the hardware to stabilize.
		+	2. Jumps to ROM code in diagnostic card (if found)
		+	3. Disables and clears all DMA and interrupts.
		+	4. Turns on the screen.
		+	5. Checks the general hardware configuration. If the screen remains a light gray colors and the tests continue, the hardware is OK. If an error occurs, the system halts.
		+	6. Performs checksum test on ROMs.
		+	If the system fails the ROM test, the screen display turns red and the system halts.

	The following colours are valid for all versions of AmigaDOS since Kickstart 1.3. However, there were several more colours in 1.3 compared to anything included after Kickstart 2.0 was released. However all of the colours listed below are the same for all versions of Amiga kickstart.		The following colours are valid for all versions of AmigaDOS since Kickstart 1.3.
