If that stream stops without you having to Ctl-C it, you may try to U8W >alogfile (stdout) and possibly do the same for stderr. As a matter of fact 286|Dos was written in MetaWare C, so it looks a bit like a C program...

Two questions from the Linux ignorant but eager learner :
What is xdos and how does it relate to dosemu ?
How should we read 0x2cd89:66 ? This does not look like a segmented address (2cd89 is > 16 bits) Would that be 2cd89 = linear address, content = 66 first byte of the faulting instruction ? Also 66, would that be decimal or hexadecimal ? And who emits that message ? DosEmu ? VM86 ? The kernel ?

No, it is not known. Could you state whether you use Win95 or 98 or ME ? Could you help me by checking whether it occurs again, without sound or music ? Possibly, is your mouse or video unusual ?
Is the message really "in VxD ---" ? Anyway looks like there has been a rather wild branch taken, I am rather sure that there cannot be any VxD at locations like 70F ...

Windows is Windows 98SE. Video is a Matrox G400. The mouse is a microsoft serial mouse. It does this whether sound set to Soundblaster or None. Files=40 (it crashed differently with the default number of files). It did this with both 1.05 and 1.08 generated executables.

Yes.

That is without sound. If sound is enabled it asks for more memory (627k is free). I think this is normal for malconfigured soundcards. I've never got sounds to work in dosemu.

DOSemu can run on the console or from within Xwindows. If you run from the console, it can access the video display 'natively' using SVGAlib, so it can actually switch into mode 13h and the SVGA modes. This is much faster and looks a lot nicer. You can get unstuck if the program malfunctions.
xdos is the X11 version. It creates a little window and resizes it to the screen size. It's 'safer' than dosemu on the console, but slower and I have problems with the mouse.

It's dosemu. I've just looked at the code and it's part of the general protection fault handler in do_vm86.c. Its a linear address, apparently made from CS:IP, and the byte is the contents. I'm going to hack this up a bit and see what I can find.
It seems to be the default case for an instruction it doesn't like. It's a switch statement.. if it gets an IO operation or something it emulates it. Whatever this opcode is, it doesn't know what to do with it.
I'll post more details as I get them ;-)

Damn. I think I was using a version of DOSemu compiled against 2.2.18 kernel. I'm running 2.4.2 now, and so the VM86 part of the kernel will be quite different.
The problem is that now I've recompiled DOSemu with extra debugging, it doesn't crash out anymore. Instead, I get a stream of Divide Error messages and a Phar Lap crash:
..then again, perhaps this will be more useful to you.

Sound problems and other queries (anybody who could help -_-) Bear in mind that I'm a technilogical illiterate, so anything weird involving, say, DOS is gonna screw me. I'm running Win98, using Pagan off of the UC, running the cheat mode. I can run U8w fine. The game works great, and I can usually avoid crashes and whatnot. However, I can only get sound right after I save a load, which means I usually get a Guardian quip and a couple of footstep. I get the music track consistantly. I'm running a Sound Blaster varient. Any ideas would be appreciated. Also... <slight U8 spoilers, but not biggies>
When I give the apprentice Necromancer (whos name I can't remember), he runs through the entire ritual of killing the old Necro, but after he summons the ghouls, a big quake is summoned. This quake seems to go on forever. I haven't waited longer then a couple of minutes; should I? Sorry if this is not very clear, I'll be glad to clarify any points.

I suspect your problem is related to the IRQ setting of your sound card. When running the INSTALL program of U8, you have to choose a IRQ setting - from memory it's 2, 3, 5 or 7. Make sure that this is what your computer thinks is correct - look up your card in start/settings/control panel/system/hardware/sound, music devices/your card/resources. More boring details are on my Ultima 7 For Beginners page :)
Re the earthquake: From the Origin tech help page.......
"When I am watching Lothian being sacrificed, the screen won't quit shaking!" Continual shaking of the screen is a problem related to your Sound Card's IRQ setting. Run the INSTALL program from the C:\ULTIMA8 directory. Ensure that the settings are correct. If you know them to be correct, but cannot get past the shaking, set the game for NO sound and NO music. Save the settings for the install program and run the game again. Without sound, you should be able to get past this point, save the game again, run the install program and reconfigure your sound for the rest of the game. See our Sound Card Help Page for more information.

Agreed. 66 hex is not an opcode. It is an instruction prefix that enables 32 bits registers in 16 bit mode (and vice versa). So whatever did crash was coming from after this byte. Pity it did not tell more, like the full set of registers ... That would have helped.
