    You are right, but DOSEMU is Linux-only (and not the easiest software to configure). I did a prototype using an i8080 core and CP/M (obviously without file access), which is tiny (some 30 KB...

    May I ask, what is it that you are working on, if it's not a secret?[/QUOTE]Basically, an application-specific DOSBox-alike, so an emulator. I want/need to be able to run a true DOS, support FOSSIL,...

    Generally, IDE devices support some form of CHS (geometry) adressing. LBA was introduced long after CHS, and while it is the better option, compatibility issues somewhat mandate CHS support. So the...

    I will have to dig into this at some point as well, unfortunately. Do you know any specific document (or good code) pointing out pitfalls, or is it better to simply consult EtherDFS? My usecase does...

    Hi,

    Some editors (such as EDIT) make it very easy to leave whitespace around. Whitespace shouldn't matter, so a warning might be more annoying than helpful.
