Do they work well with the adapters? I recall reading of possible issues somewhere, but I can't remember why.

I'll try to mess with it some more tonight after work with these suggestions and see what happens, though I'm still going to get a different board ultimately. Heck, maybe I'll end up building TWO dual Tuallys. Why not? 😀
Re: Dual Tualatin 1.4 GHz build - motherboard selection

The Asus needs a terminating adapter in the second slot if only using one CPU, which I don't have, but I will try swapping them between the sockets and reinserting a few times. Pins are all good, I looked them over carefully and they insert easily. And the manual says the CPUs have to be matching to …
Re: Dual Tualatin 1.4 GHz build - motherboard selection

My Google-Fu must be weak, because I can't find out for sure if the Intel STL2 will work with 1.4-S CPU's but apparently the chipset performance is pretty good. I'd rather just go the new motherboard route rather than troubleshoot the Asus board, because even if I get it to work, that board only has …

They're both SL6BY chips, I made sure to get those.

That sounds like a beast. Gaming isn't going to be the primary use of this system. Probably a little UT99 or Quake 3 just occasionally so I'm okay with PCI video.
Dual Tualatin 1.4 GHz build - motherboard selection
Posted on 2020-09-16, 14:44
Hi all. I'm trying to build myself something I've been meaning to get around to for a long time. A dual Tualatin P3 1.4 GHz system. I tried it with an Asus TR-DLSR server board. This one apparently came out of an HP NetServer LP1000r according to the BIOS. The board came with dual 1.26 GHz Tualatins …
Re: Faux86 - an 8086 emulator for Raspberry Pi that runs bare metal
Posted on 2020-09-02, 18:01
Hey, cool. Fake86 was my old PC emulator. The code is awful though. It might be worth redoing this with my new emulator, XTulator. It's basically Fake86 2.0. The CPU code is still mostly the same (for now) but most of the rest is rewritten to be cleaner and better. There are some improvements (EGA/ …
Re: Is there a relativly safe way to convert a VirtualBox harddrive image to a format QEMU expects by default?
Posted on 2020-08-31, 17:20
You can use QEMU's qemu-img tool to convert. This is from memory, but I think the command line is: qemu-img convert -f qcow2 /path/to/source/file /path/to/destination/file Or -f raw for raw format. qemu-img --help will tell you if I'm remembering that right...

Good work! Have fun, writing a PC emulator from scratch is a process full of blood, sweat and tears. Lots and lots of tears. But once everything comes together, it feels awesome!
Re: XTulator (yet another PC emulator)
Posted on 2020-08-31, 14:47
Thanks! I looked at your link. This does allow you to use base memory all the way up to the beginning of CGA memory with these command line parameters: -mem 736 -video cga But you'll have to build build a custom binary of the Super/Turbo XT BIOS to access it all, which is very easy to do. …

As you can see, I've completely given up on the concept of organization by now. I just have too much stuff. The other corner of the basement, not pictured, has even more stuff. I think I have a hoarding problem. It's amazing how much stuff can pile up over 20+ years. https://i.imgur.com/DaLZgH5.jpg
Re: ATA/ATAPI secondary master without primary master?
Posted on 2020-08-25, 19:05
So which of the two happens? Does it appear on the secondary master/slave without any primary master/slave drives present(all returning 0s on reads)? Or does it move to the primary master and slave without a secondary master/slave present? I stealth edited quickly after I realized that was …

Yes you can do that.
Re: XTulator (yet another PC emulator)
Posted on 2020-08-24, 21:08
Thanks for the link, I'll read through that tonight. Yeah, the CPU emulator is pretty unoptimized. It's actually taken right from an emulator I wrote 10 years ago with only some minor modifications, and that old PC emulator had a slew of poor design decisions and poor code all around so I decided to …

Current features: Full 80186 instruction set support Standard XT-class PC chipset support (8259, 8253, 8237, 8255, 8250) Microsoft-compatible serial mouse CGA, EGA/VGA Sound Blaster 2.0 …

Using OPL3_WriteRegBuffered instead of OPL3_WriteReg fixed the issue. Reporting in case anyone out there from Google has this problem in the future...
Re: Espejo (x86 emulator)
Posted on 2020-07-15, 17:03
Is it possible for us to compile from source? This sounds like a promising emulator. After you said Moon Bugs doesn't work in all those other emulators, it made me curious about my new emulator too. It works if I start it with the CGA adapter module instead of VGA. Does it fail on real VGA cards?
Nuked OPL3 strangeness with channel volume output
Posted on 2020-07-08, 00:06
I'm putting Nuked OPL3 in my emulator until I can make my own sound decent, and I'm noticing that for whatever reason the volume of the channels is kind of all over the place. Like in Ultima 6, some of the channels are so quiet that they're virtually inaudible, while others sound correct. And in …
Re: VGA write implementation on 80186 PC emulator
Posted on 2020-06-19, 19:33
I figured it out. I forgot my 16-bit CPU port I/O functions were still placeholders! Stupid stuff. :) It fixed other issues like the cursor in text mode not changing position from 0,0 and probably other things I haven't noticed yet. I also added a few other things to the code, including supporting …
