I assume that you have no trouble in booting the PB from Disk 1 of System 7.5? DFA is only 176kB, and Drive Setup 312kB, on a 500MB HDD, so you can fit DFA on Disk 1 of System 7.5 with no trouble already. Alternatively, at the outset you could make a copy of Disk 1 and replace System 7.5 Installation and Installer with Drive Setup and DFA to give yourself a Disk Tools disk, in effect.
