[comp.sys.ibm.pc.hardware] IDE and ST-506 Disk controller - co-existence possible?

Does anyone out there know if you can use an IDE disk controller card 
simultaneously with a standard ST506 controller card? I currently have a
WD1003V-MM2 controller card and want to upgrade to an IDE disk (and thus have
to add an IDE controller), while keeping my existing drive. I know both cards
have settings for primary and secondary i/o address. But do any of the current
crop of BIOSes support this secondary address. For that matter, does Xenix
support this secondary address, since that is my primary reason for having two
drives.

Thanks for any help
