My computer absolutely refuses to let me install Linux of any kind or even allow VirtualBox to run  :P

I've asked FinaleTI to try it out, so expect a message from him.

EDIT: Z80man, did you ever find the location of the screen, because I can shotgun my RAM to find it if you haven't.
Is this an official technical term, or did you just use it here.  I like the analogy either way.  Sorry to hear about linux.  This is why I have 2 computes. ;-) One to test fun stuff, and one to use normally.

I'm downloading the iso for Ubuntu 10.10 as we speak so that I can set up Virtualbox.

Excellent, thank you!

Unofficial, but I think it makes the process sound appropriately destructive :P

Of course, I'm assuming that the FLASH is write locked in virtual memory, which is NOT something I want to be proven wrong on...

I've hit a slight roadblock in the USB protocol process...


Edit: I found a program that read some info on the Prizm over usb, but I'm not sure if the data I've got is what you need.
Should I post it, or email it or what?

I sent you a PM. Ask if you have more questions, as I may have not been clear enough.

It was clear and I believe it worked out perfectly fine.

Problem is Casio hasn't even released a downloadable version of the OS yet.
Which is a shame because right now several people are stuck with the first version of their OS, which is buggy.

Yeah.

Also, if anyone wants to program in ASM using add-ins and you're using absolute calls, check that the virtual memory bit of the MMU is reset. If you do not, you're probably going to generate TLB and/or page faults.

So are you going to shotgun your RAM? Be sure to take video of any weird anomaly.  Quick question, though, but do you think if you bricked it, CASO would replace it?

Is using add-ins to do ASM possible right now? You ran ASM code successfully before if I remember. Would it just be a matter of making sure the app remains the right size and to not overwrite the checksum?

@graph, I've tried, but it generated page faults and I don't have time to fix the problem at the moment. And I doubt Casio would replace my Prizm. Good thing ROM is write locked.

@DJ, the apps are stored in ROM and copied to RAM to run, I think. I've tried overwriting them before with no success.

So this means your CPU speed changer add-in from a month ago actually never ran successfully and was pretty much a hoax? ???

No it worked (as far as I know). This is different code. The CPU speed changer didn't throw TLB errors.

Oh ok, but couldn't you just replace your CPU speed changer with different code and it would work? If so, then someone would just have to write a temporary software to modify existing add-ins as a solution to the potential 2-3 years of wait (what it took for the Nspire, the TI-82 and TI-85) before Ndless/ASH/Zshell arrives on the Prizm. :P
