My first step was to plan the partition layout and create it with 
gparted. ROOT, HOME & INSTLLR were formatted ext4.

(hd0,mdos1)  unused
(hd0,mdos2)  unused
(hd0,mdos3)  ROOT  /
(hd0,mdos4)  extended
(hd0,mdos5)  SWAP  swap
(hd0,mdos6)  HOME  /home
(hd0,mdos7)  INSTLLR

(iso, initrd, vmlinuz) are in INSTLLR.  There is no need to overwrite 
INSTLLR during the installation. INSTLLR can be joined onto /home

Yes, my human error.  I omitted putting the iso in the folder before 
the last trial run yesterday.

That definitely helps.

The installer then gives the option to search for USB devices.  It 
gives no evidence of a hdd although it's running from one. (?)  In the 
snapshot of console 4, the last line reports "devices found: ''".  
Meaning "no devices found".

Then I put the iso on a SD card in a USB adapter.

The installer finds that iso.  Ie. boot from (iso, initrd, vmlinuz) in 
INSTLLR and let the installer search USB devices.  The iso in a USB 
connected device is found.  

Preliminary conclusion. The installer can be started from (hd0,msdos7) 
but the iso search fails to acknowledge existence of (hd0) and fails 
to find the iso in (hd0,msdos7).

Does the installer search algorithm work in the msdos extension? Not 

Does it ever work on the extension?  Don't know yet.
