Dealing with cd's that don't read.

Hi all,

Ive had a few cd's that ive not been able to read under Jnode (on real hardware). Ive discovered the following sequence seems to make it work with the current development head.

key: Command (result expected)

Boot from jnode cd.
cd /devices/sgo
dir (listing works)
cd .. (devices)
cd .. (jnode)
device stop sg0

device start sg0 (error from file system mounter - cannot read bootsector of sg0)
device stop sg0
device start sg0 (mount works)
cd devices
cd sg0
dir (spins up cd and reads ok).

Use Wink to create a movie of how JNode works.

The few times I have actually managed to get JNode to boot on my hardware, and then only in text mode, I have quickly run out of things I could do with it.

I wondered if one of those who know, and have a virtual PC/vmware/whatever could create one of these movies which show what the software can actually do.

As vmware now have a free product which is usable for non-trivial use, I think such a thing might be beneficial to those who have no idea yet what this is capable of.

Just my 25 øre.

tools for debugging.

Ive been trying to debug the iso9669 device to find out why it doesnt show any files for one of my cd's.

it occurs to me that its really hard to see whats going on, just because of the number of classes and interactions within them.

One software tool i use has a method trace feature that causes the VM to output the method name whenever it enters or exits a method.

it would be a useful "coarse" tool to see which classes are involved with a given action.

FOSDEM

Hi,

Is anyone going to FOSDEM in Brussels at the end of this month?

CD ROM device shows no files.

Ok, so ive got it booting more or less reliably now (with the latest sources). The devices I get are hda0, hda1, jnode and sg0.

doing a DIR command in the sg0 drive shows no files at all. It does spin up the cdrom though.

suggestions?
