Help getting my CD-ROM drive working in my A2000?

[Huxley_D]

As you guys might know from my other thread, I'm slowly getting my Amiga 2000 back up and running. After a long session last night / this morning, I've managed to get a leaking battery snipped and removed, two mostly-working floppy drives installed, my old Zeus 68040 board installed with an on-card 40MB SCSI drive, and Workbench 3.1 installed on the Zeus drive. Whew!

While I was extracting my Amiga stuff from my storage locker, I also found my old NEC CD-ROM drive, which I was using with this A2000 at some point ~8 years ago. However, now that I've got a plain-jane Workbench 3.1 install on the freshly-formatted HDD, I'm having a terrible time getting the OS to recognize / mount the CD-ROM drive. I've gotten the CD0 file into the DOSdrivers folder with the correct SCSI ID set (and I've tried multiple ID's + multiple ID jumpers on the drive), and CDFileSystem is in the L: folder... but no luck. I've got an AmigaOS 3.9 CD I'm trying to mount, and when I insert it (with all the software set as correctly as I think I can), the drive LED blinks, I can hear the disc spinning, but... nuthin.

Here's a pic of the label on this CD drive - maybe it's just not compatible?

I've tried with and without the termination jumper set, too - no difference that I can tell.

Thanks for any tips!

Do you have the correct SCSI device specified in CDFilesystem? CD should be at end of SCSI chain with terminate on.

Thanks for the help! CD drive is at the end of the chain, and I'll make sure the termination jumper is set.

Re: your first question, I'm not 100% sure. How do I find the exact SCSI device name for the CD drive when it's the second item on the chain from the Zeus's internal SCSI port? Not sure if this will be helpful, but here's a (pretty lousy) pic of my current "Show Config" results:

Thanks again for chiming in - I'm *so close* to getting the CD drive working, which will get OS 3.9 installed, which will help me get the Zeus drivers + ethernet drivers installed, etc. etc.. Basically, I feel like I'm on the last domino before they all start falling one after the other! :-)

The SCSI unit id is set via the jumpers on the CD drive itself - placement along the SCSI cable has nothing to do with it. You also need the SCSI device name to configure CD0. For example, Commodore's SCSI controllers use the name scsi.device. You need to find whatever name the Zeus board uses. Quick way is to hold both mouse buttons while booting to get to the early startup control menu. Then go into Boot Options - you'll see all your partitions on the right along with their device names and boot priorities. Take whatever name you see next to your boot partition - let's pretend it's zeusscsi - and use that name with CD0. By default, CD0 will have scsi.device, so change that to zeusscsi.device, or whatever popped up in early startup control. (Just remember to append the .device, which is not displayed in early startup control).

If you need to find out what unit number the CD drive is set to and you can't figure it out from the jumpers, change the icon info of HDToolbox to use zeusscsi.device, or whatever the name is. When you open it, it should find your hard drive and another device that it has no idea how to handle - that'll be your CD drive. Note the unit number and modify CD0 accordingly.

Fantastic info, thanks!

I just came back to the A2000 after a nice long nap, only to find it dead. Specifically, the machine powers up when I flip the switch but I get no disk activity, no flopping-seeking, etc., as long as the Zeus board is inserted. The machine behaves normally if I remove the Zeus board. FML. I've spent the past ~hour reseating the Zeus board, removing it's metal bracket (the one that faces out the rear of the chassis) in the hope it was catching the case and causing the Zeus to not "sit down" fully into the slot, etc.etc., and I'm stuck. The '040 CPU gets very warm when the machine is powered up, and it seems like the three-finger ctrl-Amiga-Amiga keyboard reset is doing something (based on flickers on the display and the sound of the Zeus-mounted SCSI drive going through it's power-on chatter), but otherwise it's KO'd right now. AARHGHGHGHGHGHG.
