804.0. "VD0: ???" by OASIS2::BERNARD (Have Gun - Will Travel) Wed Oct 14 1987 13:37

All right... I give up.....

What the heck is VD0:  ???????

I just spent a good bit of time searching for "VD0:" through this notesfile
and came up with bunches of references to this beast but not what it is...

Do I grow it, install it, buy it, is it RAM:  hard disk... or what...
Do I need it...  am I the only kid on the block without it.....  etc...


My guess is that it might be the non-destroyed-RAM:-on-reboot-device but
I really don't know.

    VD0: is a warm-boot recoverable ram resident disk-like device.
    This is a shareware program written by:
    
		Perry S. Kivolowitz
		ASDG Incorporated
		280 River Rd Suite 54A
		Piscataway N.J. 08854
		(201) 540 - 9670
    
    I haven't used it all that much yet, but now that I've gotten some
    fast memory I'm sure I'll probably start.
    
    I still have this online.  I'll put it in:
    
       ant::bipolar:[smcafee.public]asdg.shar1
       ant::bipolar:[smcafee.public]asdg.shar2

804.2One more file...MORRIS::SMCAFEESteve McAfeeWed Oct 14 1987 14:0920
    
    Forgot to mention...
    
    One of these shar files has a file called DeleteRamDisk.uu in it.
    That file is bad.  A "good" version is also in:
    
      ant::bipolar:[smcafee.public]DeleteRamDisk.uu
    
    Actually, for anyone new to this notesfile, there are several people
    who graciously maintain directories with all sorts of amiga goodies
    in them.  Most of these folks post frequent messages telling us
    when they have made something new available.  Generally, you can
    find what you want by poking around in one of these areas.  Of
    course to be kind, one shouldn't bog down the network with large
    file transfers during the day.  Of course, at night...  (I'm going
    after "The Dream Goes Berzerk" as soon as I get a chance).

804.5Help me, modify my startup-sequence for VD0TRUCKS::BUSSINK_ESwitzerland 700th, D-3Mon Jul 29 1991 06:3141
    This is the only Topic that I got thru DIR/TITLE=VD0 *
    
    I tried to install the VD0 yesterday evening on my system. But I want
    to Relabel the name "ASDG-RAM:" to VD0: .
    I can insert the command 'Relabel "ASDG-RAM:" VD0' in the
    startup-sequence, and it will work when the computer is turned on. But
    when I WarmReboot my machine, it will try to relabel, and with give an
    error measage, which is normal due to the fact that there is no such
    name. Could anybody help me with my startup-sequence.
    
    
    Turn the computer on.
    
    	Startup-sequence
    	 |
    	 |
    	 mount VD0:
    	 relabel "asdg-ram:" vd0		Ok
    	 |
    	 |
    
    	WarmReboot
    
    	Startup-sequence
    	 |
    	 |
         mount VD0:				ok
    	 relabel "asdg-ram:" vd0		error message 20
         
    
    Can I use something like this :
    
    	|
        mount vd0:
    	if not asdg-ram:
         relabel "asdg-ram:" vd0
        endif
        |

804.6Here ya go...FROCKY::BALZERChristian Balzer DTN:785-1029Mon Jul 29 1991 07:3520
Re: .5

From my "home" startup-sequence:

...
mount vd0:
if not exists vd0:t
	echo "VD0: not found - installing..."
	relabel drive vd0 name W
	makedir w:t
endif
assign t: w:t
...

You don't have to assign t: to vd0:, it just's that way in my case.
Even a "dummy" directory that will be lost during a power cyle will do.

Cheers,

804.7Could this work in my Startup-sequence, to mount & relabel VD0TRUCKS::BUSSINK_ESwitzerland 700th, D-3Mon Jul 29 1991 11:5012
    Could this work :
    
    in my Startup-sequence
    
    ...
    mount VD0:
    if exists ASDG-RAM:			if ASDG-RAM: exist then it will
    	relabel "ASDG-RAM:" VD0		 rename the device.
    endif
    ...

804.9VD0 startup-sequence fix.TRUCKS::BUSSINK_ESwitzerland 700th, D-2Tue Jul 30 1991 06:5025
    Well, it did work, but got an Requester for Drive ASDG-RAM during the
    startup-sequence. Not very neat.
    
    so here it is now.
    
    ...
    mount VD0:
    if not exists vd0:disk.info
    	relabel "ASDG-RAM:" VD0
    	copy dh0:VD0.info VD0:disk.info
    endif	
    ...
    
    	This will work far better. By checking if there is a Disk.info in
    	the VD0. If not, it will copy a pre-snapshotted Disk.info to
    	the device. (This will allow you to have neat Disk icon for the VD0)
    	The only problem here, is that if you delete Disk.info from VD0,
    	and reboot it will try to relabel the device, and will return an
    	failat 20 error message.
    
    Some people mailed me, and do not seem to understand, that while RAD
    (that's what I have read) takes ram space, even when it's empty. VD0
    doesn't. :-)
