ok - i do understand the point. and i do guess the hint was also
included in ady's answer.
why running a 32-bit kernel? well because of efficency. i am running
ldap, bdb, mysql db, webservers, e-mail server with imap service on a
512mB RAM kernel without swapping of over 10 years. so - why should i
step up to a 4gB environment? it's all about point of view and
capabilities. i am also developing on 8bit microcontrollers. works fine
on a 20cents cpu as long as you know how to use it and no oo and no java
is envolved. yes - different needs.
other reason would be ... it is not possible to do so. as i do
understand your statement.
hard to understand now .... i have got a x64 system, the vendor claims
to be good for running 32-bit windows and 64-bit windows systems on. 2nd
statement from intel saying 64-bit cpu is backward compatible to run
32-bit applications. can i understand an OS as an application?
so where is the key to glue all statements to one single picture? how
looks the korrekt picture - please?
|-syslinux.32 -> linux
32-bit
|- boot32.efi - |

32/64-bit
x64 UEFI - |

|- boot64.efi- |
|-syslinux.64->
linux32/64-bit
thank you.
