I know the ROM startup disk is in the ROMs for the Classic and LC, and I thought that the IIsi shared the same ROM chips with the other two models, however upon trying to boot up while holding down cmd-opt-X-O my si still booted off the internal hard disk. Though I have no desire to run my machine as a diskless workstation, it would be nice to be able to boot off ROM to edit finder resources, delete offending INITs, etc. Any info would be appreciated. -Glen

The ROMs in all the new machines are 512k. The Classic ROM doesn't need to have color support in it, so they can put in a 358k ROM disk (which, with only one font and System 6.0.3 seems a bit useless...) along with the standard Mac operating information. The IIsi and the LC have 32bit QuickDraw in ROM, plus, I believe, the sound stuff (don't know about that for sure.) Regardless, there isn't room in the color machines for a ROM disk.
