applied, thank you. also fixed some bugs in code:
properly convert the register values from the 386 ureg.
read back #P/realmodemem on every access as some graphics cards
use the a segment as memory mapped i/o. (Matrox MILLENNIUM)
we dont use #v/vgabios anymore and rely on #P/realmodemem to

yes. you should use libmach to do this dirty work.

Thank you for explaining this.

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 buffer.

Again, I'm delaying testing because I need to install a different

yes, this started as 8i from russ. it was renamed to realemu after i
made it into a fileserver providing /dev/realmode and
/dev/realmodemem. this way i dont have to reimplement aux/vga's vesa
code and it can be used as drop in replacement. (just start it before
running aux/vga)

Why TARG=qi in the mkfile (I would have guessed 8i, but I could be
wrong)? and I think the error:
term% mk install
cp 8.out $BIN/qi
rc: null list in concatenation
mk: cp
for everyone running realemu, please try with the new version to
see if i broke something.
the changes include:
switch back to textmode works now, as we use #P/realmodemem to
wite back changes to physical memory in the range B-A.
with realemu and the patch (see below), i'm able to switch
15 matches
