Zitat FAQ Fasa http://www.shadowrunrpg.com/resources/sr3faq.shtml#3
ZitatIt says that attribute modifications from bioware are considered "natural" and not "augmented," meaning that they affect the attribute's base rating. Does this also mean that an attribute modified by bioware (not counting cyberware) cannot exceed the Attribute Maximum? What happens if my human character with natural Strength 6 (and Strength Attribute Maximum 9) gets muscle augmentation 4?
Strictly speaking, bioware cannot raise an attribute's natural rating above the Attribute Maximum. So the human character described above simply doesn't need muscle augmentation 4 (and the street doc would probably tell him that ... or maybe not, and just give him muscle augmentation 3 and keep the change). If the character had muscle augmentation 4 installed anyway, his Strength would still be limited to 9.
If you desire a more high-powered game, then you can ignore this rule and allow bioware to exceed Attribute Maximums. The character's natural attribute ratings should never be allowed to exceed the Attribute Maximums, however, and you may wish to inflict bioware-stuffed characters with system overstress or other excessive bioware drawbacks (p. 78, M&M).
