I have tried If you read the enhancer docs you would find that you can't auto-boot off of an FFS-formatted RAD:. The reason is very simple: the FastFileSystem driver is not in Kickstart/ROM, and so must be retrieved off of the boot disk, so you end up with the catch-22 of: you can't boot until you can read RAD:, and you can't read RAD: until you can read the FastFileSystem off of disk, which you can't do until you boot, etc... So, if you want to auto-boot off of RAD:, is must be using OFS. The FFS/autoboot HD controllers do this in one of two ways: either they put FastFileSystem in the controller ROM, or they put it on a reserved track on the disk (that the controller ROM knows about). I don't know why RAD didn't do that. > Thanks alot!!!! > scot > sjk@astro.as.utexas.edu -- --------------------- Scott Henry #include
