Many Apple Performa and Power Macintosh computers now include an L2 cache which improves your overall system performance. Apple is aware of a problem which disables the L2 cache feature on some Performa and Power Macintosh computers after installing Mac OS 7.6.1 or the 54xx/64xx Update extension version 1.1. This problem also occurs on several models of Mac OS-compatible computers based on Apple's logic boards with an L2 cache. This extension corrects the problem and improves performance on affected computers.
