Hey everyone,

So I recently got interested in these old Iomega Bernoulli drives. I've accumulated a number of them now... at couple each of the 20MB, 44MB, and 150MB variants. They were all SCSI... or so I thought... until I realized one of the 150 MB "Multi disk" drives I have is actually IDE (or ATAPI).

It was found as a stand-alone drive, not inside an enclosure. If I install it on a Windows 98 box, it can read disks as a generic "removeable disk" drive.

So naturally I now want to find "native" drivers for it. Ideally I'd like to find some ATAPI drivers for it that lets it work in DOS. However, Googling this thing brings up NOTHING. I've tried a 4.1 version of GUEST.EXE and it didn't detect it.

It has a BIOS chip labeled "B150 IDE 17.1T" on the PCB.

Is anyone here familiar enough with these to know the best Iomega tools to use for these drives? It has a manufacture date of late 1994 stamped on it. I cannot find any Iomega documentation about it... but I hope it's just my lack of imagination on how to find anything.

Any historical knowledge about these drives that anyone can share would be great. That is something that has interested me in these drives-- they seem to have been around for a number of years-- but it's like history has almost forgotten about them. Especially how Iomega driver revisions match up with these drives.

Thanks
