I couldn't make head nor tail of the Dell f2/f12 boot options.
installed bullseye and all was stable at 800x600 but with no options to 
change. As want to do graphical things that's not ideal.
Upgraded to bookworm via changing /etc/apt/sources.list and installed 
firmware-linux-nonfree, changed resolution to 3840x2160 desktop crashed 
while displaying firefox.
Still no option to choose CDrom in dell boot menus.
"efibootmgr -n 8" and reboot runs bookworm install CD.
on reboot after installation of bookworm PC says no OS found.
Changed Dell f2/f12 menu to boot legacy CDrom and bookworm installation 
succeeds, has automagically set display to 3840x2160 and hasn't crashed 
as yet so we see how it goes.
