RAD: on AOS4.0

I'm using AOS4.0 Pre-release 4.


I can't figure out how to make a RAD:

I know how to do it on AOS1.3.3, which is alter the highcylinder (I think it was) in the mountlist file, then "mount RAD: from mountlist".

But there isn't a mountlist file anywhere here on the HD.

Can anyone tell me all the steps to do to make it please?

Quote:In AmigaOS4 final there is a RAD mountlist in Storage/DOSDrivers and Documentation/Kickstart/ramdrive_dev.doc which describes how to create a RAD: which survives a reboot.

Hi joerg,


Thank you for that information.

Does that mean that RAD: is unavailable on AOS4.0 Pre-release 4?

@Atheist

No, check sys:storage/dosdrivers & move RAD to sys:devs/dosdrivers, ud4 & final.

Hi sundown,

I did that, then I changed the high cylinder value to what I wanted.

Then I did
mount devs/dosdrivers/rad
and it said "MOUNT: Device "rad:" is already mounted"
Info didn't show it. I tried cd to it, that didn't work. I tried to format it from the shell and couldn't.

I tried
mount devs/dosdrivers/rad:
and it came back with "MOUNT: Could not open input file 'DEVS:Mountlist'."

There is no mountlist file that I can alter to open a RAD: and don't know what to put in one to make it from scratch, either.


I tried
format device=rad name newram
and got "format failure: Error -1"

And also tried
I tried
format device=rad: name newram
and got "format failure: Error -1"

I'm not sure what to do to get it started.

@Atheist

"Format"is only for floppies. You don't have to format a RAD Disk or a RAM Disk, there are no tracks or sectors to format.

Changed what? The value in the text file "RAD" or the tooltype in "RAD.info"?

Did you reboot after changing the HiCyl value? Because if not, it was already "mounted" with the old values and you can't "unmount" it.

Hi tonyw,

Arrrgghhh!

I changed the value in the RAD.info file!

I thought RAD was a program and tried to run it. In 1.3.3, the entry was in "mountlist" and never even considered loading "rad" into notpad.

No, I didn't reboot, but even though it said it's mounted, there was no icon on the workbench for it. I'm afraid of altering anything on the HD because my memory might not be working (if you saw my 1 Gig ram thread, you'll see why.)

I'm so embarrassed.

I finally figured out how to get it going.

First of all, in the RAD text file it says to change the size of the RAD in tooltypes. Unfortunately it should say to keep it an even number of cylinders, by making "HighCyl" an odd number. Apparently you'll get a problem otherwise, probably a guru. (In the text file it says "Increasing this value (HighCyl) by 1 consumes an additional 11 K of ram." I wonder if the increments of only one causing a problem has been eliminated?)

That I already knew. I find it strange that LowCyl is even defined, I mean, what (or why) the heck else could it be other than zero?

Anyway, the reason I couldn't get it to work was that I did
Copy DH0:DEVS ram:devs all clone
Then I copied "rad" and "rad.info" to "ram:devs/dosdrivers", modified the HighCyl value in tooltypes, but DIDN'T "assign devs: ram:devs", so it couldn't find the file I had made. It was looking for it on the hard drive.

For anyone else trying to use it, then you have to CD or list it, to activate it. A requester will pop up asking if you want to mount it. (See last paragraph.)

I made RAD: and RAD1:. SO cool! Before on my A2000, I only ever had one. I don't know if more than one is possible on it (AOS1.3.3).

It's disappointing, but nice at the same time in a different way that HighCyl has to be set by a tooltype entry, because on my A2000 I had written a shell script that asked me to enter the size of RAD: I wanted, then modified the mountlist file with the new size, then started it.

Oh yeah, it took a bunch of guesses at the shell prompt, but to get the requester not to appear, one has to enter "mount rad:" in the shell. It makes the icon appear on the desktop. I had never achieved that on my A2000 1.3.3. I ALWAYS had to do a "list" or "cd" to the rad: to activate it.



Edit:
Thank you for all the help, all.

IIRC tooltype entries are preferred by the Mount command over
mountlist entries, so when you want a changed mountlist entry
to be used you have to remove the tooltype entry first.

@Atheist

Sorry, i'm in a hurry and no time to read entire forum.

But this is what i do when mounting RAD:

Open shell and type rad:
AmigaDOS asks what to do, press mount.

And voila i have a "standard" floppy, i can format it, i can write *.adf and *.dms on it like into a normal disk.
