If the imac DVSE came with 8.6, then 86. imac install media will work,

90's. If its not the correct line it says this system version will not
work on this macintosh. I will look as i do have 8.6 on an original
ibook, and imac but I have not tried the media in a DVSE.
The iMac firmware update would be a good idea, and it *must* be done
before attempting to boot a CRT iMac with any OS X disc.
Rather than check the firmware version right off then gracefully quit
with a report that the firmware must first be updated, OS X will booger
the PRAM and Open Firmware data *then* tell you the bad news. It can be
quite a chore to get the iMac to boot back to Mac OS so the firmware can
be updated.
