Actually you can make changes to os9boot using dEd.  You just have to be careful and understand what you’re doing.  There is even a function in dEd to calculate new CRC.

If you see the 'rb1773' driver and 'f0' or 'f1' descriptors in memory then all you need do is a 'dir /f0' or 'dir /f1, with a disk in the drive to access the files. If rb1773, f0 and f1 aren't in memory then they will need to be added with the kwikgen command.
