"ECP mode" in your BIOS settings.
There are two ways of doing ECP: doing the protocol using the three
'normal' registers (status, data, control), and getting the hardware
to do it for you (switch to ECP mode, write the data out to the ECP
register).
2.2 doesn't do either of these.
The ppdev patch for 2.2 will do the former (which will be slower).
2.4 will do both.
