It drove me mad

   Yes, you're right ! However, TUNES is a software project: few of us can
afford hardware development, and I don't feel a hardware solution can be
useful (remember our motto) before we could demonstrate the value of our
concepts by a software implementation, as no one would even care for it.

   I intend to make it clear how using the BIOS is a temporary hack that
will help me debug everything. However, I feel we need some real-mode
access later, and there are still services (like VESA BIOS, custom hardware,
etc) not easy to reprogram and update ourselves. Not to talk about later
having V86 and R86 access to allow users to run DOS-in-a-Box. So I'd really
want to have working such accesses anyway.

   Currently, I have problems with m4 whose diversions seem to be completely
buggy, so I cannot use them to emulate segmentation :( :( I'm beginning to
feel like I'd rather program a quick LLL first in any language (aka C or
FORTH), then do it all from there...
