I would not suggest it. First, you can get cheaper hard disk drives these days. The IOMEGA is SLOW! Real SLOW! Almost the same as floppies. It was unbearable running a UNIX file system on it. It would take forever to read the entire disk. Second, the media is not cheap, around 80 dollars per cartridge. > > What we want to know is > > Have anyone out there used a "Bernoullibox" with a UNIX like OS? > (We have seen the 5Mb box for MAC.) Yes, I wrote a driver for XENIX for the INTEL 310 (a multibus box) using a 80286. The drive was a two 10mb drives on the single controller. > > We have heard that the IOMEGA has a SASI interface, is it possible to use it > with the SCSI port. > No, it uses a SCSI interface.

I used an EMULEX HA01 host adapter. The thing was really preliminary. Both the first and second manuals I got were terrible. They sucked. It took a long time to fix the boards to work despite the grossly wrong switch settings, and then to get the driver to work with all the misinformation in the manuals. Fortunately, EMULEX customer support gave me a lot of good help over the phone. The Host Adapter is not my favorite design. It is extremely minimalistic and you have to do a lot in your driver software to make it work. The problem is that there just aren't any decent MULTIBUS host adapters. The only other one currently on the market (DTC) does not do parallel multibus arbitration. > > Can anyone help us with a driver (source) for the Bernoullibox.? > No, the company I wrote it for has a vested interest in recovering the money they gave me for writing the code.
