I need to edit the contents of what will be the C drive when dos boots, though it probably doesn't have a file system on it. Anyway i'll need to boot up from a floppy because it has a pick r83 system on the C drive. Not sure what the system is, so fdisk and some simple tools like that would be nice too. Anyway any help would be appreciated. I'm searching for someone local with 5 1/4" floppies and blanks I can use, but if one has a disk i can get from someone I'd be glad to send compensation. For Pick folks (Mr. F15) I don't know the sysprog password, and need to null it out. I may pull the drive from another system I have that I do know the passwords for, but this new system I just got is working, and I'd like to log in and see what this system has and back it up. Pleasantly surprised it has an AST 6pack in the expansion (included) in the kit. thanks Jim
