I called Western Digital on this very subject...I bought an ESDI controller,
and wanted to use my old ST506 as a secondary controller.  They *assured*
me that even if I got the addressing and interrupts changed, it wouldn't
work.

If that's true, then why do all the controller cards have secondary address
jumpers????

Is there anyone out there who has two controllers (SCSI doesn't count!)
running in the same box happily???
