Who wants paragraphs in 2008?

Yes, segments are horrible in real mode, but it doesn't affect MikeOS because the kernel (and loaded programs) reside in a single 64K segment. So that isn't a problem.

Regarding 32-bit, please see the FAQ section of the Handbook. In summary: 32-bit is naturally better if you want to write a full, serious, general-purpose OS. But when you're learning x86 assembly and want to piece together your own OS, 16-bit real mode is much better, because you have access to the BIOS.

This means that you can focus on doing interesting stuff (loading programs, making new system calls) instead of spending the first few months writing tedious keyboard and floppy drivers.

No, I mean paragraphs as explained here:

Just a funny name for a 16 byte boundary under x86 real mode.

To each his/her own.

Viva la MikeOS! :-) Wed, 09 Apr 2008 21:26:00 GMT donotreply@osnews.com (Rugxulo) Comments http://osnews.com/thread?308944 http://osnews.com/thread?308944 The BIOS will go at some point in the forseeable future. Relying on it existing is not a sound assumption. You would benefit more from writing the drivers and severing the 16-bit restrictions.
