Re: Configuring AMI 386dx bios for CD

The Soundblaster CD connector is not emulated in PCEm (and as such there is no way to tell that the CD is connected to there). So that's probably why you can't configure it like you had it back then. You might need a different driver and connect it to primary slave. Not sure if adding a SCSI card in...

Re: PCem v15 Sound Issue

MIDI audio on the AudioPCI is done in software while in the other Soundlblasters is done by an emulated chip ( an OPL on most of them, and the EMU8000 on the AWE32/64). Also, there are two OPL emulators, DBOPL and NukeOPL (Selectable from the soundcard options in pcem setup). DBOPL is like the one i...

Re: Help getting external MIDI working in PCem (Linux) (No MIDI Option in GUI)

I believe that such a thing was only implemented for Windows, so the problem is that there are some missing code to do that. (It's been quite a while, so I can't be sure 100%)

Re: Confused about creating hard drive images and sizes

Re: Future graphics card emulation

And to add to the virtual machines talk... VirtualBox has had experimental support for 3D on WinXP (which seems that it was done replacing some DirectX libraries but I couldn't do anything serious), and version 6.1 has removed it.
Now 3D support is only present for Windows Vista onwards.

Re: How to install PCem v16 on Linux

There was a name change for one of the bios for pentium. Possibly that's the reason.
Also remember that on linux, the filenames are case sensitive, so bios1 is not the same as BIOS1. Ensure that the correct name is on the .cfg file.

Re: Any possibilities of emulating voodoo 5 ?

There is a thread about the possibility of emulating Voodoo 3 and basically it summarizes to: It isn't really worth, with the current hardware emulated.

So Voodoo 5 is at least many years out of question currently.

Re: Is there a command line for this?

No there is no way because DOSBox emulates one single system (MS-DOS on an x86 PC) while PCem emulates the x86 hardware and can run any kind of system.
So if it assumed a prompt based system, then that would not work for a windowed system, and each windowed system would require its own method.

Re: Network with 2 pcem machines running

It should be possible, if you use the pcap driver and configuring a bridge card. (I haven't really tested that, and the release build of PCem only has the SLiRP driver )
Not with the slirp driver, since that doesn't make it visible outside of the PCem instance where it is running.

You definitely cannot use more than 28MB by means of the AWE32 API, because the addresses that would permit addressing those 4 remaining megabytes address the internal ROM memory. About 4MB and 16MB, that's more about hardware accuracy. You had to use two 30pin SIMM modules ( https://en.wikipedia.or...

Re: PCEM Doesn't Change Sound Source Without Rebooting

Yes, that happens.

I had a quick look back then and I believe that it is not easily fixable with the current audio API. (Have a similar problem: headphones and monitor speakers).
Basically, programs that can switch audio like that do so because they connect to the default soundcard.
