I've found the following constructions with past verbs:
They found not the fire.
You knew not that.
Is this an archaic way?
Can we use with "ED" ending verbs, "crossed not the line" or just with irregular verbs?

Those are examples of anastrophe, the departure from normal word order for the sake of emphasis. It does sound somewhat archaic because this figure of speech is not used as often as it once was. You'll find it a lot in Shakespeare's writing, for example, and in modern fiction that it attempting to sound "Shakespearean."
It can be used with regular verbs as well as irregular ones. Take, for example, John F. Kennedy's famous quote: "Ask not what your country can do for you; ask what you can do for your country."
