# Shadowrun character creation, in what order do you reduce magic due to -wares?

In Shadowrun are there official rules as to when you would reduce your magic rating due to various -wares?

Point in case, if you decide to purchase say bioware at the beginning of the process, before you've purchased traits, does that make your effective magic score negative for the purposes of then increasing your magic score, or can it never drop below zero, until you take a trait which raises it to 1?

For example, which of the following scenerios is correct:

Joe soon-to-be-Mystic-Adept (a human) has decided that he really needs an embedded comlink in order to fit in with the group. He purchases this with money before he takes the Mystic Adept trait. This immediately drops his Essence to 5 and drops his Magic to -1 and gives him maximum Magic of 5. Joe then purchases Mystic Adept which gives him a Magic score of 1, regardless of his previous -ware habits.

OR

Joe has decided that he really needs an embedded comlink in order to fit in with the group. He purchases this with money before he takes the Mystic Adept trait. This immediately drops his Essence to 5 and drops his Magic to -1 and gives him maximum Magic of 5. Joe then purchases Mystic Adept which gives him a Magic score of 1 that immediately drops to 0, because of his previous negative. Joe then needs to spend 10 BP to raise that back to 1, or else he's a burn out.
