This article is from the Amiga CD32 FAQ, by Stuart Tomlinson with numerous contributions by others.

31 Is it possible to use the Aminet, Fred Fish, etc... CDs without an expanded CD32?

A: Yes, Maarten Ter Mors has written a step by step guide of how to do this. It's available from aminet:/docs/misc/Aminet4_CD32.txt. There can be problems booting from some CDs if you use an unexpanded CD32 though. Maarten wrote:

There was a little something I missed in the CD32 FAQ. Because of (yet another) strange oddity in the Commodore 3.1 CDFileSystem, you can only use CD-ROMs with a *lower* or equal ISO revision than the disc you booted from (this is irrelevant to SX-1 users, for they are likely to boot from harddrive or floppy).

The Aminet 4 CD and the GoldFish CD-ROM set by Fred Fish are two examples of discs that use a higher revision than, say, the Weird Science Network CD. This means that you can't access the discs properly or at all. The solution is booting from a RAD: recoverable RAM disk. I was asked by Urban Mueller (who does a lot of the good work on the Aminet CDs) to write a step-by-step guide to set one up.

A: Joop van de Wege has another answer (Aminet 5 & Communicator)...

I haven't read the notice yet but I found out for myself how to do it and its not a hassle. I'm just too lazy to write a small script file to copy the 2 files and execute the mount command.

Step 1: copy your mountlist entry CR0: to snet:ram Step 2: copy L:amicdromfilesystem to snet:ram Step 3: mount cr0: on the cd32 side Step 4 and last one: start copying files from cr0: to whereever you want them, run programs, read guide files, search for ......

A: And another from David Law of Weird Science (Aminet & Network CD)...

We have found that CBM's filesystem in general does not cope too well with the Aminet CDs. This may be due as you say to ISO revision numbers. The easiest fix is to remount the CD drive as CD1: with AmiCDRom filesystem and access the Aminet CD's as `CD1:` or `Network:CD1/` with Sernet. When trying this be sure to set the 'T' flag in the line 'Startup' of the mountlist. This will ensure that the trackdisk device is used to access the CD drive. AmiCDRom filesystem for some reason thinks that the CD drive is a SCSI device otherwise and will probably crash the machine.

The best way to do this is setup a drawer on your amiga with the following files in. [Call it RAM:CD1 for the mount list below - Dan.]

CD1 AmiCDRom Mountlist file. CD1.info An icon for the above. cdrom-handler The filesystem handler. Mount WB3.1 Mount command.

Just ensure that the mountlist points to 'Ram:cdrom-handler' and not 'L:cdrom.handler' and that the icon points to 'Ram:Mount' as the mount command on the NetworkCD is WB1.3 and is not suitable.

The Mountlist file is...

/* AmiCDROM filesystem */

Handler = Ram:CD1/cdrom-handler Stacksize = 10000 Priority = 10 GlobVec = -1 Mount = 1 Startup = "DEVICE=cd.device UNIT=0 ML T R"

The version of Mount should be 38 or above (use 'Version Mount' to check).
