Re: How to debug PCem

You need to have an IO handler for the CRTC ports (3D4/3D5), as svga_in/out won't handle them. You can copy basic handlers from something like the OTI-067 code.

Yeah, if you don't have a VGA mapping then it's not going to work.

Probably. But it removes the requirement for emulating a motherboard with AGP.

Re: How to debug PCem

One thing you might want to look at is if the legacy VGA address space (A0000-BFFFF) is being mapped correctly. If it isn't then that would explain the lack of VRAM access.

Re: How to debug PCem

Maybe share your changes so far, so I can see if anything is obviously wrong?

I wouldn't worry about things like the i740 for now, the Riva 128 will be enough to keep you occupied for some time. Besides, there is a PCI i740.

Re: How to debug PCem

Well, is the register trace giving you anything? If not then the video BIOS isn't running.

There are socket 7 AGP chipsets. AGP is probably a waste of time at the moment though, anything which can benefit from AGP will likely require much more performance than PCem can currently give.

Re: NT4 could not logon after SP6a installed

Is the netlogon service running? This seems more likely to be an NT configuration issue rather than a PCem bug.

Re: How to debug PCem

In the exec386() main loop, add if (CS == 0xC000) output = 3; which should give you a register trace from when the video BIOS is first executed. If it doesn't even get that far then you've got a memory mapping issue. Note that you will have to manually kill the emulator before the log gets too big. ...

Re: [Request] Diamond Fire GL 1000 Pro

Unlikely - I can't immediately find any datasheets on the Permedia 2 chip on that card, and having implemented the ViRGE and 3dfx I don't really want to have to emulate another 3D chip any time soon.

Re: Distribution packaging support?

Or might as well just work on a file browsing dialog? Not just a Linux matter, I believe it is a good idea to just allow PCem users to use their own way of organizing files...? I suspect if I do that, it would encourage people to believe that any random BIOS they find would work, which is a belief ...

Linux PCem is also fairly poor, so I'm not sure that encouraging wider distribution in its current state is a great idea.

A number of fixes get BeOS 5 working... mostly. You have to run using the 'Award SiS 496/497' system to get the mouse working, and there seems to be some kind of FPU issue.
