"chainload" will do this. In fact, it doesn't do much: static grub_err_t grub_chainloader_boot (void) { grub_efi_boot_services_t *b; grub_efi_status_t status; grub_efi_uintn_t exit_data_size; grub_efi_char16_t *exit_data = NULL; b = grub_efi_system_table->boot_services; status = efi_call_3 (b->start_image, image_handle, &exit_data_size, &exit_data); if (status != GRUB_EFI_SUCCESS) ... That means, of course, that it won't use shim on Secure Boot systems. There's probably some value in merging the two, so that chainload will use the efi stub if and only if a) it's present, and b) it's needed for e.g. multiple initrds or bad UGA/GOP data. -- Peter _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
