Using a 5.25 Disk Controller Card with the IIgs

[Tempest <tempest@atariprotos.com>]

When setting up my IIgs I wanted to use a 5.25 Disk Controller Card
for maximum compatibility with older games, so I stuck it in slot 6
and set it to My Card.  However now when I boot it gets to my 5.25"
drive and if there's no disk in there it hangs and never gets to my
3.5" drive in slot 5.  I think I know the problem, the old 5.25"
controller isn't smart enough to give up and pass control back, but
what I want to know is how to fix it?

Can I put the 5.25" card in a slot other than 6?  Can I say stick it
in slot 1 (which I'm not using) so that it's the last thing that the
system tries to boot from, or does it need to be in 6 for some
reason?  If so, is there a way to make it try my 3.5" drive first?
