Maybe this can help. EDIT: Oh wait, you also need the help file.

Correct 😁

copy con autoexec.bat – the lowest you can get ;) (You'll have to start from scratch, though, so type autoexec.bat first if it already exists.) For something more sophisticated this one is incredible: http://www.texteditors.org/cgi-bin/wiki.pl?T

That's exactly my motherboard – apparently it's not as exotic as I thought 😄 Thank you for all your help, Eudimorphodon! I guess I'll take the risk (even if it means a firework show). Most likely I'll have to adjust the switches (just like I'd do with the proprietary card).

Sure thing, I'll take some photos later this week! But with this one you can trust me: I do have 128k of RAM. There are only 18 4164 chips (parity bits!) in two rows; that's all there is, no placeholders on the motherboard, no empty sockets. The diagram that's floating around is either a...

No, it has an 8088-2 clocked at 7.16 MHz and an 8-bit ISA bus. The problem is, there's an expansion slot on some motherboards (see "P7" on the schematics I linked to in my previous post) described as a "32-bit external memory card". On my motherboard there's only a placeholder (or not even that...

Ha, I didn't know that. I knew that the VGA video RAM is banked (which makes sense since there's only a 64k-long "factory default" region defined and used by the VGA standard) and, obviously, that you cannot switch to a VGA mode unless you want to ruin the data stored there, but I though that...

I stand corrected, then. I should have said that it (63s, 16h, 64c) did work for me 😄

Thanks for the detailed reply, Eudimorphodon! That was my thinking. I even tried to modify programs so that they use that region for their code and/or data, but the former (setting CS to A000 in the EXE header) crashed the emulator (I didn't dare run them on real HW) and I couldn't find...

Thanks, guys!

When I asked if you could boot from the image, I meant the "virtual" image (i.e., the .img file) :-) but while we're at it: yes, it is possible to mount physical media as a hard disk in PCem, but it requires a bit of hacking. (Again, this works in Linux; most likely you'll need to modify the...

Can you boot your emulated machine from the image that you burned to the CF card? What does dir return? If it differs from the contents of your CF card, something's gone wrong with writing the image to the card. You're welcome. I didn't help much :)

In this article, they mention a tool called Win32DiskImager. Maybe you could give it a try?

Wait, didn't booting from a 386 help? I hate to say that "it works on my machine"... but it does 😄 I've set up a "[386SX] Commodore SL386SX-25" computer with 4096KiB RAM and a 3.5" 1.44M drive as FDD1, and managed to boot Disk01.img from the link you shared. It's certainly a bootable image!

There should be a couple of ROMs bundled with PCem (assuming that's what you're using), but you can download more from this GitHub repo. Put them in the roms subdirectory of the configuration directory (I'm sorry, you'll have to find it yourself on a Windows machine; on Linux it's located in...
