[syslinux] 32bit OS on 64bit architectures

[Juerg Oehler]

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.64-> 
linux32/64-bit

thank you.
