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 …

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 …

Mega stupid question, are there any secret memory settings hidden from the user? 124 MHz - work fine, 133 - or errors immediately, or just 768 MB are detected. Maybe some "command rate = 1" by default or so? Do you have registered memory installed? If not, then that can very well be the problem …
