SUPER OS is a machine language utility for use with the BABYLON hardware upgrade. It will allow you to dump an exact copy of what is in your computer memory to disk.¢¢Specifically, it will write from $400-$BFFF. It will start writing at sector 1, so be sure to have a formatted scratch disk in the drive before SUPOS kicks in.¢¢DIRECTIONS:¢¢You must have the BABYLON hardware upgrade installed in your computer. This utility WILL NOT WORK unless unless the appropriate hardware is installed.¢¢1- Boot Atari Dos 2.5 (without RAMDISK.COM), with OPTION down.¢¢2- Load SUPOS.COM¢¢3- Place the boot disk in D1:, hold down OPTION again, press M and type E477.¢¢4- After the disk is booted, throw the switch that you installed with the BABYLON upgrade.¢¢5- Place your formatted scratch disk in D1:.¢¢6- Hold down OPTION and hit RESET.¢¢7- Your screen will blank and the drive will run as it dumps out memory from $400-$BFFF.¢¢8- When the drive stops you will have to reboot. Don't forget to reset the BABYLON switch.¢¢This is great for backing up heavily protected disks. But, it will be up to you to take the raw sectors dumped out to disk and turn it into a usable format.¢¢______________________________________¢WHAT IT DOES¢¢SUPOS creates a ram o.s., and patches the NMI chip reset vector to point to a custom routine at $CC00. Upon RESET the patch directs program control to the custom routine, which is responsable for dumping memory to disk.¢¢Some software will try and set $D301 (PORTB) upon boot. This will force the rom back on, knocking out the ram o.s.¢¢In cases such as this you might try and patch $EA's (NOP's) in this area with your sector editor. The ram o.s. must be enabled for this to work!¢¢______________________________________¢These files provided by CODEMAN.¢
