How can make sd work while ethernet working?

I do not have a problem with using the SD and w5100 together. Neither does zoomkat. Here is the setup code I use to initialize both correctly.

void setup() {
  Serial.begin(9600);

  // disable w5100 SPI while starting SD
  pinMode(10,OUTPUT);
  digitalWrite(10,HIGH);

  Serial.print(F("Starting SD..."));
  if(SD.begin(4) == 0) Serial.println(F("fail"));
  else Serial.println(F("ok"));

  Serial.print(F("Starting w5100..."));
  Ethernet.begin(mac, ip, gateway, gateway, subnet); 
  Serial.println(Ethernet.localIP());

  Serial.println(F("Ready."));
}

edit: I haven't tried this, but it looks ok to me. This is one of zoomkat's latest examples.
