This may not be a problem, but I want to make sure before I go buy another CD-Rom, one that's on the list of tested models by Emu. They say that other models may work, so I want to give it a try.

PC 200mhz/128 mb

My bus is :

Esi2k...Iomega Zip...Adaptec AHA154x
...Pioneer DR-U12X

Esi and zip work well with both cables, so it's not that.

The only thing I cannot change is the termination of the Pioneer (I could change it's ID# with the junper, but haven't tried yet, since I don't think it's the problem). I went into the Adaptec Bios and tried to see if I could change something, but it tells me "Not a disk drive". Is an internal CD-Rom terminated by default?

In the SCSI set up of the Esi, you can of course assign it's ID#, but there is also an option to tell the unit to avoid host on ID.

goes like this; "If a computer is present on the SCSI bus set "Avoid host on ID" to the computers (sic) SCSI ID number."

Now what I read here is : If your Adaptec SCSI ID is 7, set Avoid host on ID to 7. Correct? unless my PC has a SCSI ID#, wich I seriously doubt, but hey, you learn everyday.

Well,if you have any suggestion, i'll gladly try them.

Thanks

Opened the box and tried every combinations of jumper settings on the pioneer. So it seems i'm on the hunt for a compatible one.

Having just bought a Scsi zip even before my Esi-2000 arrives i had time to read a couple of pages of the Zip manual where it describes having the Zip at the end of the Scsi chain.
Seems unlikely that this could be Frostbytes solution.

If your Zip is the only drive on the chain, yes, it has to be last and terminated. But it's
not my case. Tho', the zip works fine if linked only with the esi.

Well here goes:
"If you choose to connect to an Ultra Scsi chain,make sure the Zip drive is always connected at the end of the chain.
The Zip drive does not operate at Ultra Scsi speeds but should not slow the performance of the other devices if it is connected at the end of the chain."
Extracted from page 4 of manual.

Dont know if Ultra Scsi is a feature of the Esi though.

that's something else to check for.
Thanks Ison for springing up new trails.
I wonder how many people got that problem, it's awfully quiet in here.
Maybe we should start slaggin' each other, it usually puts the threads to fire

you broke my heart, why did you have too shatter my childhood memories.

you're a no good son of a scsi Faerie !

Maybe we'll need a bunch of dirty mama jokes or it'll never rise to a 100.

the esi will work in an Ultra chain, because I spoke with support at emu and he suggested I get an adaptec AHA-2940 wich is Ultra.

In the first message of this thread, I sketched my scsi bus with an internal (in the computer) pioneer cd-rom at one end of the chain. This won't work, it's not supported in the PC.

If a PC is present on the bus, it imperatively has to be on one end of it, the esi at the other.

It arises another question: If I get a Ultra scsi 2940, how in hell am I supposed to put the zip at one end of the chain? Is it imperative that the zip is placed at the end?

In a SCSI chain generally you can't have two host devices. However, in the case of the ESI it has special SCSI so it can. No here's the important part. It's only the ESI and the Computer SCSI card that needs to be terminated. Everything else is in the middle of the chain (even an internal device conected to the SCSI card in your computer). As for Ultra SCSI. Ultra Fast is not a problem with the ESI however Ultra wide it would have to be at the end as well as any Zip drive. Ultra Wide has 60pins intstead of the usual 50.

Now, I'm only trying with the pc and the esi. I terminated the pc by putting switch 1 on the AHA 1540 C to "Closed" wich installs termination on the card. In the esi masterglobal/disk utiliies/scsi set up I put Esi(local) ID : 5 and avoid Host on Id : 7, wich is the ID of the adaptec. No luck , I've tried different ID for both the esi and AHA (did control-A at start up to enter the AHA bios and change ID in the Host adapter setting etc..)

I've been on that for almost a week now, i'm getting a bit frustrated, but then , i'm really stubborn and I don't want to spend more cash on another card, just to find out it's a problem with the esi.

Any ideas? Thanks for taking the time.

Ison is following this too (plus I guess a load of others)

Well I can think of a few things but they are kinda hard to explain. Are you on the ESI email list because this problem has been addressed there in depth. I never had a problem myself so I can't really troubleshoot...it seems with SCSI and the ESI you either get it to work right away no prob or it takes awhile to get the glitches out. At www.onelist.com there is an ESI email list search for it and then search the message archives or join and ask the question.

Thanks Jeremy.
I have started to search the archive but haven't found anything yet. I want to see for myself before i ask, since it's a bit annoying to hear some questions again and again.

I just thought. What order are you turning them on in...see I borrowed a CDrom that wasn't on the supported list and I couldn't get it to work unless I turned it on last.

Well, it all works now ,had a bit of fun with it, hence the delay for that final post

To get everything to work, you will need:

Patience, perseverence and a pair of very long nose pliers to reach those &$*!% jumpers that are so out of reach.
a huge pot of coffe is also advisable.

Here is my present SCSI Bus:

Esi2k...IomegaZip...AdaptecAHA154x ...Pioneer DR-U12X

Now, this set up works , but you have to remember that each can be different, so only a couple hints are going to be helpfull and true for every set up.

Tip number 1:

Make sure EMU media is present in each drive. Put one of the CD they packed with the sampler IN your CD rom (wether it's internal or external, or you won't be able to mount the drive)

Tip 2:

Figure out all combination of ScSI ID for each device in order not to repeat yourself when trying different ID set up. write it down

Tip 3

Power up order: This is quite obvious, but still: ESI has to be powered first if you want it to be recognised by the pc, just as any other SCSI device.

apart from that it all lies in assigning ID and have your Bus properly terminated. The ESI is already terminated. my other end is the CD-rom, also terminated. Everything in between musn't be. In Master/Global/Disk utilities/SCSI set up, "Avoid host on ID" should be set to whatever Id your Host card bears (more likely your host card will be set on 7, but you can change it in the bios if that setting doesn't work)
About the host card, make sure you have the manual, or it's going to be nightmare to configure as they made sure it was as alembicous as this sentence

Pay particular attention to the switch block settings, that's were the action is.

writting down the stuff might seem like a drag, but it really helps.

good luck !
