I have an old 8-bit SCSI card from IOMEGA which I am attempting to use in an XT system running DOS 6.22. I have installed the OAD drivers and configured the CONFIG.SYS and AUTOEXEC.BAT to reference them. When DOS boots it runs a utility that attempts to configure and load the driver. That utility finds the adapter at 330h but does not find the attached Zip100 drive, and aborts.

I don't have any documentation for this adapter, although I purchased it new long ago. I suspect I need to change some jumper settings but I no longer know which jumpers do what. Does anyone have knowledge of this adapter?

Thanks for your replies.
