I implemented INT 15h support a long time ago, and I hear no bug report on 
this. So I close this bug.

Greetings!

We're currently prototyping a system mainboard that does not have a KBC, and 
promptly have observed GRUB to run into this issue.

We've been implementing Int15h 240x functions, and could think of an improved 
algorithm in GRUB that makes better use of them - particularly in case the 
system does not have a method of switching the A20 gate at all. This is the 
case in systems that follow the MS "Legacy Free" initiative - A20gate is always 
open, and there's no method of closing it at all.

Please let us know how we can participate in getting GRUB to run on these 
systems.

regards,
Peter

I did some changes on this bug a long time ago, and I have never heard the same 
problem for a while. So I lower the priority, but not closing it, so that I 
wouldn't forget it.
