Don't forget the jumper configurations differ greatly between the CMS
SCSI ROM versions (especially between the 1989 and 1990 ROM's). Bill,
I'm pretty sure the jumpers you've listed are for the 1990 ROM version
correct?

The original poster will need to confirm that they too have the 1990
ROM (otherwise the jumpers could be different). Usually the ROM on the
card has a sticker indicating the ROM version. For the record, there
are 3 versions of the ROM - 1987, 1989, & 1990. Generally, the 1990
ROM is the best one to have.

Cheers,
Mike
