3744.0. "Booting from RAD" by JGO::CHAPMAN () Thu May 03 1990 06:07

    I'm trying to get mt RAD disk to reboot from itself and pass control
    to my janus harddisc. This works OK, at least it always starts to
    work OK, but there seems to be some conflict between between RAD:
    and RAM:. Any time that the startup-sequence in RAD: come across
    a reference to RAM:, the execution stops with an error message.
    
    For example, I originally had:
    
    	makedir ram:t
    	assign t: ram:t
    
    in the startup-sequence above the point of handover to jh0:. The
    error message says can't make directory or some such. I have a line
    which says
    
    	date >ram:datefile
    
    and I get the error message 'can't open redirection file'. I've
    tried a few other examples, and it always fails at the first mention
    of ram:
    
    I'm baffled. Any ideas?

3744.1	A guess...	BOMBE::MOORE	Eat or be eaten	`Thu May 03 1990 16:45`	2
	Did you put a copy of MountList and associated device drivers/handlers (i.e. the stuff in DEVS:) into RAD?
3744.2		WJG::GUINEAU		`Thu May 03 1990 19:15`	4
	How much memory do you have and how big is your RAD device? You may be making RAD: to big so that when you put something into RAM:, it has no room left. john
3744.3	I'll check devs:	NMGV11::CHAPMAN		`Fri May 04 1990 04:35`	8
	I have 3meg and am only making a small rad:, so memory shouldn't be a problem. I'll check how much of devs: I copied to rad:. I thought I copied all the relevant bits, but it is possible...... Thanks Colin
3744.4	Ram-Handler?	FROCKY::BALZER	Christian Balzer DTN:785-1029	`Fri May 04 1990 07:37`	9
	Re: .0 You do have the L:Ram-Handler available when trying to access RAM:, do you? If you boot from RAD: this should be RAD:l/Ram-Handler... There are some other files like the Disk-Validator and the info and icon library that come in handy on a minimum boot disk/partition. <CB>
3744.5	Works now, but...	JGO::CHAPMAN		`Wed May 16 1990 12:20`	13
	Thanks! Had everything else. Thought I had ram-handler. Checked it, Didn't have it. I spent a lot of time trying to tune my startup-sequence so as to save time on a RAD boot, even to the extent of copying a separate startup-sequence into RAD:. The conclusion was that I couldn't save more than a few seconds off my approx. one minute startup time, principally because binddrivers takes so long over janus.library. At the expense of about 110k RAD: it just wasn't worth it, so I scarapped the idea. Colin
