What exactly is your problem? It doesn't make sense.(to me)
For DOS use Dosbox and compile the cross compiler for x86.
Or simply download the original TurboPascal from the Embarcadero website. It is free.
(1.0, 3.0, 5.5, 7)
Needs an account to download, but the account is never misused.
Although, technically, the fpc cross compiler is better.
What you need to understand that is that FPC needs to be built from source for some platforms. If that is a problem for you, ping me and I do it for you.
