Geoff's explanation to me a long time ago wasn't quite as emotional, but was
quite helpful for understanding what was actually going on:

the /dev/realmode intraface was not documented, but it is very simple.
/dev/realmodemem is just an image of the first megabyte of
physical memory that is addressable from 16 bit realmode.
plan9 reserves a 4k page at 0x9000 (defined as RMBUF) that can be
refered to in the bios call as data

Thank you for explaining this.

That being where the machine's BIOS resides, if memory serves.
Plus whatever can fit in there if one
in /dev/realmode, you write a struct Ureg (from /386/include/ureg.h)
(in x86 machine byte order?) containing the register contents and the
interrupt number of the bios call you want to make.
yes. you should use libmach to do this dirty work.

his modified 9load that allows you to pass new plan9.ini variables at
boot. I got disconnected before I could acknowledge. I haven't tried
it yet, but it could be useful.
not quite sure what you mean by this, but
Cinap suggested invoking realemu in a subshell so that the
process exits after aux/vga completes. The following is a patch
for the man page.

Hi,
In 9P, if I wish to list a directory, I need to TWalk to the directory,
TOpen the directory fid from the walk, and then TRead till I have all of the
contents of the directory.
If the directory's contents do not fit in a single read, I imagine I need to
loop around TOpen / Tread / / Tread
