NOT!" -- Anthrax >*** .signature randomizer 1.0 * write for free c source Well, they HAVE done it. My Classic here can do the Command-Option-X-O on startup and boot from ROM. Cool but useless. I also did this at work to connect to our AppleShare file server. It works! It even stores the automount volume info in Parameter Ram ( or at least a portion of Ram that can survive a reboot). But there's a problem (unless AppleShare 3.0 will change things)... I have had some bizarre crashes at startup with this (finder is damaged... yeah, right, it overwrote the ROM? Give me a break!) config. Here is the info as I read it on my screen right now: Finder 6.1x <--- Seems to be possibly RAM upgradable???? System 6.0.3 System memory usage = 166k You can't start up under MultiFinder You don't have access to printer drivers... The only Font available in Monaco 9 point. The Brightness CDEV is version 1.0d2 and has a Horizontal orientation!!! Macsbug is in there (evidence that this thing is buggy!) in ROM... AppleShare Prep file is there, but looks bogus (info stored elsewhere). No printer drivers (major problem). Only Control Panel and Chooser available. Basically, a neat hack that doesn't do much (the ROM seems to be copied into RAM anyway, as no memory is liberated by the ROM stuff...). Boot Disk 365,486 bytes used, 357K on disk, for 9 files Where: hiding inside this machine...
