<> <> <<>> <> name ExtraIago <> ExtraIago is the start of a set of routines for dealing with the disk errors that mainly occur on the AMS-315 disks. It includes routines for reading through the system files (checkpoint, vm, etc), deleting system files, interrogating the bad page table, adding pages to the bad page table, making sure the bad pages are marked as allocated, reading disk pages and printing out their contents, and more. ExtraIago is invoked by the Run command in Iago, which asks for a file name; you type /Indigo/Cedar5.3/Iago/ExtraIago.bcd. ExtraIago adds commands to the set offered by Iago. Type ? to see the full list of available commands. Note that ExtraIago can only be run on a machine that has a working Cedar file system. It will run in the Cedar5.2 world as well. Like Iago, it is only necessary to type a unique prefix of any command. <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> <> << Orr>>
