Hi, first and foremost thanks for PCEm: the feeling of having my first PC ever up and running is so genuine that it's giving me the chills. Quick question: is there a reason why for hard disks the IMG format was chosen over VHD? Is support for VHD eventually planned? Thanks You can convert VHD to i...

This is a patch to model.c by me to allow use of 286 CPUs on XT systems for a speed increase.

As I said though, Windows 2000 works okay for me, with pretty much the same configuration you're both using.

RTM is the final release before service packs.

That's the only way I know. Thanks for stopping by!

Hello, and welcome to my first post on the forum! I've absolutely loved this emulator so far and hope it continues to grow. I'm especially excited for the in-development Pentium emulation and the 3D acceleration -- the latter especially hasn't been attempted much on emulators thus far. So, anyhoo, ...

Yep, the BIOS ROMS I'm using are the correct ones. Checked the MD5 checksums for them and they come out the same. I can still boot it. It's just a little bit annoying. Looking at the info I can find, it seems to suggest that it might be a problem concerning how the clock is emulated (looking at wha...

POSReady 2009 is basically XP but still supported and some multimedia stuff removed. It also uses a graphical install right from the beginning. Problem was that the install freezes shortly after the format options screen. Config: CPU: Pentium 133 Mem: 256 MB GPU: S3 Trio64 BIOS: Award 430VX PCI HDD:...

Found wininit.exe and wininit.bak, but not wininit.ini.
98 is in the VM BTW.

Ok, time to fix my win98 install then upgrade to XP. (on 6G Virtual HDD)

Where is wininit.ini typically located?

No idea, I haven't tested it. Has anyone?

I haven't, but I will try POSReady 2009.

ote="Battler"]- nerd73: I think you might have faulty copies of the OS'es. I got NT 3.1 and 4.0 working without problems in PCem, and SA1988 did the same with NT 3.51. Remember, that first, a lot of NT 3.x copies floating around on the internet are patched to make NT auto-assume a Pentium ...

one of the main reasons to migrate to PCem for legacy operating systems :) Yeah, although NT OSes are a bitch to get working. Stripped XP installed, but explorer.exe did not work, so I was stuck at cmd.exe 2000 had hard disk problems NT 4 did not recognize the CD-ROM drive NT 3.51 worked until grap...

And we need to get back on topic.

Why suggest how Tom increments PCem versions? It seems many here already compile from source, so it wouldn't affect them. Perhaps it is so that others obtain versions without bugs? In that case, then the unfinished ne2000 patch would likely introduce additional bugs into trunk because it is under-t...

I'd rather not have the 18 month development time again. v8's development was a nightmare. In any case, I think the recompiler will probably be a major enough change for a release on its own. True, but then people would think that outside the recompiler, v10 would not have much else added. And it s...

TomWalker wrote:It's on my todo list after the recompiler matures a bit, so I don't know if that will be v10 or 11.

You should make v10 like a major release, like how v8 was over v0.7 (lots of new features and bugfixes)

Not for me, I can get to Win95 and Win98 just fine without any IFSMGR bluescreen on Intel Advanced/EV and AMI Winbios 486 with the DYNAREC enabled. Did you build it? I should mention it's nice not seeing the Win95 logo stalling for seconds and having the full speed of a Pentium 90 :) I have built R...

Got improvements:

Max speed in no skipping test:

Interpreter: 75 MHz 486
Rev 173-186 recompiler: 80 MHz 486
Rev 187 recompiler: 100 MHz 486

Nonetheless the Pentium Overdrive/83 is quite consistent.

Copied more opcode timings and removed the cycle dividing crap. Integer is still not as fast as i'd like it though (doom benchmarking seems very inconsistent - 890 realtics in one, 1400 realtics the next - in ultimate doom demo1). didn't have much time to work on this also tried to conform more to ...

Hi, I found there's vid_voodoo.c and vid_voodoo.h in the src folder, and "voodoo_init();" was found in pc.c. However Windows does not recognize the Voodoo card. Does Voodoo emulation really works or it's dummy? BTW, Bochs does the Voodoo emulation now. Maybe there're some ideas can be fou...

To amuse myself and to learn more about how PCem works I wrote this patch that adds a few Cyrix 6x86 CPUs to the Award 430VX PCI motherboard. Currently it's a useless patch at it halts before POST. No timings adjusted and CPU code scares the freak out of me to dig farther into why it does this. It'...

This is code that adds Pentium Overdrive for 486 systems emulation.
There were two models released, 63 MHz (25x2.5) and 83 MHz (33x2.5).
This requires the dynamic recompiler to be enabled.

Unable to enable dynamic recompiling.
On 64-bit windows.
I add -DDYNAREC to makefile.mingw, and it compiles successfully, but it doesn't seem to pick it up.

EDIT: Working now.

Awesome!

Is the FPU even emulated on the 386? Last time I checked it was 486 (DX obviously) and higher only.

Tried a recompile today (after the commit Reorganised FPU emulation) and still get crashes on open could it be cause ive got a intel i7 cpu which has lots of cores? or due to the fact that i have two grahpics cards the dedicated card only gets activated while gaming...
