Hi, I have a questions about the asm code at the top of hvmloader.c: This code overwrite the lower part of memory with the trampoline code. Doing that, it overwrites some interrupt vectors there. Why we dont care about that? Many thanks, J _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The rombios initialises the IDT and enables interrupt delivery. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
