四分律行事鈔資持記 2.242

2.242

分不定中。一切，謂七分也。《俱舍》即有部計，謂比丘戒方得七支，是具戒故；餘三、四支，以非具故。若準成宗，四戒竝發七支，即皆從一切得定也。今依彼引，宗計須知。

Under 'indeterminate divisions': 'all' refers to the seven divisions. The Abhidharmakośa represents the Sarvāstivāda view, maintaining that only with the bhikṣu precepts does one obtain the seven paths, because they are the complete precepts, whereas the other three [types of precepts] have four paths because they are not complete. If based on the Chengshi school, all four [types of] precepts arise with the seven paths, which would mean that all are determinately obtained from 'all'. Here he cites the former, so that school's assertion must be known.
