It's impossible to install from a Backpack CD-ROM drive using paride.img, because it never loads parport_pc: ... bpck: paride ... paride: parport parport_pc: parport parport_probe: parport pcd: paride ... It should be 'paride: parport_pc', and 'parport_probe' doesn't even want to be there.
This seems to have gotten _worse_ in beta2. Now it doesn't load _any_ modules: * loaded 9 keymap tables * extracting pattern 2.2.16-3*/parport.o * ejecting floppy ... and a message saying "Failed to mount driver disk."
This issue (paride.img), which has been there since beta1, seems to be different to bug 12809, which appeared in beta2 but not in beta1.
Tim, I'm closing this as you've checked in a fix. Please make sure it works in beta 4.
(It does.)
