[ros-dev] ReactOS gdt limit

[Henning Schild]

Hello ROS dev-team,

i am currently working on qemu/kqemu and found that ROS sets the gdt
limit to 0x800. At least this is what i see in qemu, i did not check
ROS source.

This may or may not be a problem.

For all i can say ROS was the only of many different OSs that triggered
the check in my setup. I may be wrong and wont investigate this any
further. Just wanted to let you know.

I used this version:
http://prdownloads.sourceforge.net/reactos/ReactOS-0.3.4-REL-qemu.zip

and that are the values i saw:
base = 0x808bdac0
limit = 0x00000800

regards,
Henning
