reset the emissions disco 2004

Hi, I have taken the disco to get the inspection but it did not pass the emissions (Catalyst not ready) and (Evap not ready). I drove the disco for a 100 miles prior to taking it in. Can someone tell me what I need to do to pass the inspection? All is well with everything else. The battery was disconnected at some point I suspect.

I don't know the differences, but this is from RAVE:

Drive Cycle "D" is the one I've seen referenced the most on the web.

Code:

The following are the TestBook drive cycles:
 
Drive cycle A:
1 Switch on the ignition for 30 seconds.
2 Ensure engine coolant temperature is less than 60°C (140°F).
3 Start the engine and allow to idle for 2 minutes.
4 Connect TestBook and check for fault codes.
 
Drive cycle B:
1 Switch ignition on for 30 seconds.
2 Ensure engine coolant temperature is less than 60°C (140°F).
3 Start the engine and allow to idle for 2 minutes.
4 Perform 2 light accelerations (0 to 35 mph (0 to 60 km/h) with light pedal pressure).
5 Perform 2 medium accelerations (0 to 45 mph (0 to 70 km/h) with moderate pedal pressure).
6 Perform 2 hard accelerations (0 to 55 mph (0 to 90 km/h) with heavy pedal pressure).
7 Allow engine to idle for 2 minutes.
8 Connect TestBook and with the engine still running, check for fault codes.
 
Drive cycle C:
1 Switch ignition on for 30 seconds.
2 Ensure engine coolant temperature is less than 60°C (140°F).

I had my battery disconnected for several months last year when I was overseas and wasn't really thinking when I got home and reconnected it and took it in for an inspection the next day and failed! Different states have different rules reguarding pass or fail on the test but here in Texas if you are 1996 or older you can have 2 things show up as "not ready" and on later vehicles only 1. Usually your Catalyst will reset last of all.

What are the exact fault code numbers, without them we can't really help you.
Also, there may be an actual problem and it will need to be repaired before you can clear the codes.
