Thank you for the above suggestions..
 although none of them provided any joy.
No matter what I do the Install gets to a 'starting installer'
or something like that,
On a later machine you see the screen Blink at this point.
obviously the installer is switching mode from standard VGA,
which seems pretty silly for a text install !
Anyway,  I booted the CD on a later machine, and learnt the keystrokes up till the hdd format.
so..
Tab, Enter    <- to skip CD checking
Enter           <- to accept English language
Tab, Enter    <- to reformat hdd
from here I blindly hit, Enter, Tab and Enter
and the format appeared to start, and after a while the Copy of files from CD to the hd filesystem
Eventually the CD was ejected,  so I hit enter.
The system rebooted...  and while holding my breath !
  It Worked !!
So the sme build itself supports my machine,
it is just the installer itself  that doesn't !! (go figure!)
So now I am at the point of migrating the mail..
Any good ideas on how I migrate the mail from one HDD  to a different HDD on the same Physical Laptop ?
There is NO facility for both HDDs to be present at the same time.
