Careful: The version in the header may imply that fields are there which you aren't aware of. I think you need to adjust the version field too. (Obviously along with FirmwareVendor you definitely also want to change FirmwareRevision.) > Create only one ConfigurationTable to store VendorGuid and VendorTable. What do you mean with "Create only one ..." - there is only one.

How is this last sentence related to the handling of RSDP? Jan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
