It seems that OS9 makes changes to your BIOS that are irreparable. >Interesting, no? > Extremely, given that Macs don't have a BIOS... (ok, the new ones have ROM in RAM which I suppose is very remotely similar...) And incorrect... I personally know people who have gone back to OS8.6 from OS9.0 or even maintain two hard disk partitions with different OS versions (I even think Adaptec recommends this a workaround for some current problems with Toast). What you may be referring to is what David Chambers described a while back... At 9:26 AM -0800 11/1/2000, David Chambers wrote: >Except.... THE NEW G4's WILL ONLY RUN MacOS 9.0 or LATER. It is >totally impossible to install 8.6 on them As to original problem of CellQuest on a G4 I can see two solutions - give up on CellQuest (give FlowJo a try!) or keep pestering BD to come up with the patch to allow CellQuest to work with OS9.0. Adrian Disclaimer - I have been beta testing for Treestar and they have given me a great T-shirt (except for the fact that my wife won't let me wear it :) ) Dear all-- I spoke to technical help at BD last week and was told that they are diligently working on getting CellQuest to a point where it will be OS9 compatible. In fact, the tech claimed that availability is projected for next month. The clincher: Mac will soon upgrade to OS9.02!! Is there no end in site?!
