Multiple RAD devices on AMIGA 500 with extra fast ram

[Tenacious]

You have probably tried this.  How did it work with 1 RAD: device sized large enough to hold 3 floppies (2640K)?  You would probably have to create directories for each game floppy and assign its logical name to it.

Have you tried running a large Workbench in RAD: with all your favorite utilities and patches in it?  Cool, huh?

In fact, i haven't tried this!  You actually suggest what  bbond007 told me , but instead of using ram: use rad: . Well, how can i try this? Change the highcyl parameter of rad device in mountlist to 80X4=320 to hold 4 floppies? And instead of diskcopy, use copy df0: rad:[dir name] /all 4 times?

Yes, that makes sense.  I would think the first floppy of the game is the bootable one.  It should go into the root of the RAD: and you could rename the RAD: to that floppy's name.  The additional floppies would go into their own sub directories of RAD: and their names would each be assigned the original floppy names so the system could find them as required.

Well not exactly, how ever i did try to make a rad out of the workbench disk and suddenly amiga became 5 times faster! :lol:  Everything from initial loading to just opening a folder is MUCH, MUCH faster with RAD version of workbench. And this kind of experience makes me VERY anxious of how would it be if i could play a "RAD" VERSION of universe, curse of the enchantia, cruise for a corpse,legend of kyrandia (ok this would be "half rad" as the game is 8+1save disks!!!)!

Maybe you could do a super Workbench first with a large RAD: to work all the kinks out.  Then, try games and those that might have unusual boot blocks.  This may only work with games that can be moved to a hard drive (standard, non-copy-protected boot blocks).

Which version of Workbench are you running?  Do you have plenty of docs about RAD:?

Besides keeper2k fast ram and the "classic" add on's of a 2nd floppy and a trapdoor ram nothing else exists in my A500.So i use the classic 1.3 workbench.
 Maybe i will give a try the method you propose, although i doubt it will work, because games usually expect a specific disk volume (in any device, df0:, rad:, hd: etc) to load files from, so i doubt it will "see" and load the files from directories within a disk volume which, apparently, will think it's still the boot disk of the game and no the one it needs.
Then again, who knows? :rolleyes:

You're blazing a seldom explored trail, don't give up!  It is amazing to me that very few have embraced the RAD: as a way to dramatically improve performance.

I've test the "big rad" with extra disks as directories in the rad. unfortunately, it doesn't seem to work, at least with a couple of multi disk adventures i've tried it. It boots ok from ram but then asks for "disk 2"...
As it seems, if you can't add multiple rad drives into fast ram it can't be done.Maybe ramdrive.device is limited to 1 rad only. At least in the workbench's 1.3 version.

After you copied the contents of disk2 to a directory on the big RAD, did you then Assign that directory to the original volume's disk name?
