Thats good, because I have later on discovered a few issues with eCS/MCP/WSeB, LVM, 
JFS and BootManager.   The issues are not data destroying and you will not be in 
any risk area that I can foresee.  And as you personally, are not using eCS or MCP 
or WSeB then you will never strike them or even be aware that there even are problems.

I am having now to use both BootManager AND Air-Boot. !
The stupid thing is that I still am booting to eCS with Air-Boot but BM has to be 
on the disk only so that dumb, stupid LVM can write to it.!  at#$at#at#.!  :(   :(

It seems IBM have made a few assumptions and some strange decisions 
concerning BM and LVM and also JFS.  Strictly my personal opinion of course.

I will not go into detail yet, but I am hoping the author of Air-Boot will get some
info and help from a few IBMer's out in the newsgroups.  Unfortunately, he does 
not have a copy of eCS/MCP/WSeB to play around with LVM, BM and JFS.

He is using Warp 4 and of course it works perfectly with that. As well he uses
(reluctantly)  windows and also linux of some sort.
 
See you end of Feb.
