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

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.
