I have not seen the instructions posted in the "into to comp.sys.amiga",
so I can't comment on what may be wrong.  Here are directions that I
wrote about a year ago for creating multiple RAD drives.
Be warned that all of these kludges probably won't work (and probably
won't be needed) under version 1.4.

------------------------------------------------------------------------
Unfortunately, RAD's ramdrive.device is hard-coded as having the volume name
"RAMB0".  One cannot create multiple RADs by simply changing the MountList.

To create multiple RAD devices:

READ ME FIRST:
   Byte-offsets are counted starting from 0, the first byte of the file.
   Both byte-offsets are for v1.0 of the ramdrive.device, created 6-Apr-88.

   The letter 'X' is used below as a place-holder for a unique character to
   differentiate the multiple RAD devices.  If you are creating a first
   duplicate RAD, I suggest you substitute '1'; if creating a second
   duplicate RAD, substitute '2', etc.


1.
   Edit devs:MountList and duplicate the original RAD: parameters.
   Change the name of the duplicate; for example, from "RAD:" to "RADX:".
   Change the "Device = ramdrive.device" line to "Device = ramdrivX.device"
   Only the original RAD should be allowed to autoboot.  Add the following
   line to the new entry to keep it from autobooting:
   BootPri = -129


2.
   Copy devs:ramdrive.device to devs:ramdrivX.device
   File-zap devs:ramdrivX.device and change "ramdrive.device" to
   "ramdrivX.device" by changing byte 171 (hex) from 'e' to 'X'.
   Also change "RAMB0" to "RAMBX" by changing byte 5A1 (hex) from '0' to 'X'.

3.
   Mount RADX:.

You can do anything to this new RAD that you could to the original one.
Things like changing the HighCyl to get a different size, etc.
