Я попытался выполнить некоторые операции записи/чтения в файловых системах, для которых я перечислил. Проблема в том, что когда я хочу записать в другие тома, а не в свой (fs0), он вернет WRITE PROTECTED Error.
... Enumerated and opened all available volumes successfuly
efiStatus = root->Open(root, &token, L"xxx", EFI_FILE_MODE_READ | EFI_FILE_MODE_WRITE | EFI_FILE_MODE_CREATE, 0);
if (efiStatus == EFI_SUCCESS)
{
char* myStr = "Sample Content";
UINTN myStrSize = strlenEx(myStr);
efiStatus = token->Write(token, &myStrSize, myStr);
if (efiStatus != EFI_SUCCESS)
{
Print(L"[X] ! Error [%r]!\n", efiStatus);
}
Print(L"Found Some\n", efiStatus);
}
Я также пробовал ShellCreateDirectory, ShellWriteFile. Действительно ли я могу получить доступ к записи на жесткий диск (pci) из приложения EFI?
