Also, if you’re playing around with bochs on your home machine, you can boost the IPS (instructions per second) in the 452mkemu script to make bochs a lot snappier

I resized the file image as it is too small.

$ resize2fs otherfloppy.img 2M

With CS 452, a lot of time can be spent seeking out the information needed to do a particular thing (like implementing a PS/2 mouse driver, for example). Spending time finding these things does not seem useful, especially when it’s been found before and it’s not integral to the point of the course. So if I can make this information available (since I found it in the past, for example) then it will make the lives of future CS 452 students much less painful.

By the way, you should add OpenID support to your blog. Among other things, this would allow you to let OpenID-authenticated users post without moderation.

Out of curiosity, what brings your advice to this doorstep?

Unfortunately, the course staff haven’t updated the cross-compilation page yet. If someone wishes get it updated, I suggest pestering the course staff every once in a while until it’s done.

It would be nice if someone could confirm that this works with the latest GCC (currently 4.3.1). I would suggest using the latest versions of all the tools, but I suppose if you don’t want to deal with any unforeseen compile problems when you switch back to the school servers, then you’d want to use the versions they use. In practice, such compile problems almost never occur.

As for IDE, I have been using GEdit but might try Anjuta soon. My computer is pretty slow with Eclipse, unfortunately…

Yeah, my thoughts exactly. I’m really new to linux too. I wonder if it’s possible to have an always-open ssh session in the background… I also read something something about mount a remote directory as a drive that might speed up the scp. I guess that I have something to play with once we hand in this assignment

Are you using eclipse? It’s like living in the lap of luxury..

It would be nice to combine scp and ssh into one single ssh call so that the connection isn’t established and reestablished twice. But my Linux Fu is not strong enough
