Page fault when pressing F1 on version 1(0.99q in Historic)

Post by Twilighte » Mon Mar 13, 2006 10:42 pm

I get a page fault and quit to dos when executing this under virtual pc. It's never been a problem with version 0.99l though that version doesn't support setting the program counter in debug mode otherwise...

This is what i get...

True, this crash occurs systematically under Dos...
I only noticed it recently when trying Virtual PC, because all my test platforms had at least Windows 95.
I will have a look at it, I guess it's due to cwsdpmi, which doesn't protect all the memory pages unlike Windows does...

I actually got similar crashes on some versions in different situations:
- When sending data to print (ex: LLIST)
- When saving (ex: CSAVE)
- When accessing the disk selection menu

Recently I got no problems thus, wonder if this is a system specific issue, because I noticed that using VDMS for example changed the patterns, makes things crash or work differently.

Fabrice, perhaps you could recommend a version to go back to that is a little more advanced than L (Such that allows me to change the PCounter) but which won't crash my VPC?

Version L has a few annoying issues, which you may be able to tell me if the more recent versions sort out?

When running code that has irq disabled thru SEI, F8 does not reset Emu!

And where do i get this from?
Also, this build i believe has a windows installer, which is not ideal for my VPC DOS environment :(

As usual, on http://oric.free.fr...

No, there's no windows installer, the distribution is in zip package that you extract wherever you want. Windows users then execute the setup.js script, this is not needed for Dos users...

Cheers,

Fabrice
