Updating Arb Source Flash ROM

* power up your vxi mainframe and source

* Run "/opt/e1432/arbsrc/srcutil -u" for usage.

* To update source flash ROM run "/opt/e1432/arbsrc/srcutil -P"

	CAUTION:	The Arb Source will be unusable if srcutil
			is interrupted when it is actually erasing
			and programming the Flash ROM.

	NOTE:	If this process is interrupted and/or is unable to
		program the ROM, a recovery procedure is documented in
		/opt/e1432/arbsrc/romfix.txt .

		The E1434 requires mechanical disassembly for the ROM
		recover process.
