I was hoping for Tualatin support, but I managed to pick up a CUV4X-D for cheap that you already made a BIOS for, so I'll probably run some Coppermines in the GA-6BXD. :) Okay. :-) You can still try the attached mod, if you like. There a no fancy changes, just a few tweaks to make the BIOS handle …

Hi, I know this is a long shot, but how hard would it be to add support for the Gigabyte GA-6BXD ? Hi, since this would be pretty much a new build, I won't have enough time to do a complete port in the near future. Is there anything specific you would like to try? I was hoping for Tualatin support, …

Re: No PCI device listing on boot, only 2 devices when I scan the PCI bus. Devices work fine though. Help?
Posted on 2023-11-09, 22:20
https://github.com/riplin/hag/blob/main/src/system/pci.cpp#L14 should read continue; , not return; . Currently, you abort on the first unused slot number instead of skipping to the next slot number. Yeah, I also just figured that out when I just brute force dumped all the data regardless of what …

Yes, config is set to auto. The devices work, the issue I'm having is that when I iterate the PCI device list through ports 0xCF8 and 0xCFC, I only get the two devices back shown in the picture (the chipset devices). Not the video card (Trio64 PCI) or the Promise UltraATA card or the 3COM network …

Hi folks, I'm writing some code for my own enjoyment and for that I need to scan through the PCI device tree to find the video card. The problem is, I'm only seeing 2 PCI devices, which are just the chipset devices. Nothing else. The system also boots up without any PCI device listing, which I'm not …
Re: I disassembled an S3 Trio64 BIOS and am annotating it
Posted on 2023-10-06, 23:04
Would the beep function be for when the bios is told to print a bell character (ascii code 7) ? The function to output the bell character is Func0x2xe0. Beeps are also emitted during the POST, usually if the video memory test fails or no monitor is detected. You have PlayBeepPattern for that. You …

Re: Which old programming languages do you still use/play with today->

I'm coding C and ASM in Microsoft C 6 on DOS. I'm used to programming C/C++ on modern hardware.. and coming from that realm I find it funny what MS-C 6 does to support real-mode programming. Dare I say real-mode under ASM is easier? The only thing that keeps me from going full ASM is that I find it …

Are you employing an adequate mechanism to center the CPU at the socket? If it's leaning forward or backward and not perfectly centered, then you will have issues with the pins not making good contact. There is a good, inexpensive DIY method to achieve this, if you're interested in hearing it, make …

I’m getting a boot hang all of a sudden with post code 61h. Searching online says it’s a reserved code. 4.51 bios says “set boot speed”? I don’t understand why I’m all of a sudden getting this issue when the only thing I changed was putting one of the side panels on the machine. :( this is on a p3b …
Re: Sound Blaster CT3900 on a ASUS P/I-P55TP4XE motherboard only works on irq 2?
Posted on 2023-08-23, 03:24
The original Dallas should be a DS12B887 which is different from the DS12887, DS12887A and DS12C887. Each has it's own unique features and some are and some are not cross compatible. I do not know of any replacement for a DS12B887 due to an additional 64bytes general purpose ram not included in …

I haven’t tried without the promise card, but it uses different irq’s (I’m using an ssd drive so need TRIM). What’s weird is that I could have sworn that this setup worked fine when I had it on the bench. I ordered a proper rtc replacement, perhaps that will fix it. Could be that this board doesn’t …

Hi folks, I'm trying to get my CT3900 sound card to work on my Pentium 133Mhz system with some sane settings. Right now it only works if I set it up to use Port 220h, midi port 300h, IRQ 2, DMA 0 (yeah, weird) and DMA 6. It will refuse to work with any other settings. In the BIOS I've tried setting …

Hey, thanks for the link. Basically I was hoping to find a clang/llvm replacement for Watcom. As much as I love Watcom, it’s missing a lot of modern comforts (auto, constexpr, lambdas, stuff like that). I’m actually a little bit surprised that there isn’t a fork out there that adds DOS 32bit support …

Hey, I'm looking forward to be able to order an Orpheus II in the next batch! I've been reading up on it and looking over what kind of issues I could run into and one thing that I noticed is that my P3B-F motherboard BIOS (looking at the docs) doesn't let me reserve DMA 7 for legacy ISA. It does …
