Re: [ros-dev] ReactOS gdt limit

[gedmurphy]

Hi Henning.

This has been fixed in r33007, it will be in the next release (0.3.5) or you
can try a trunk build if you're brave : http://www.reactos.org/getbuilds

Thanks for taking the time to report this.

Regards,
Ged

The IDT Limit should be 0x7FF, and the GDT limit should be 0x3FF.

I believe ReactOS sets the IDT Limit incorrectly, and perhaps the GDT  
as well.
