It'd be neat to get these CPUs working on a board with an ISA slot. - Alex

Re: new Windows 2000 fan project writes drivers for modern hardware
Posted on 2023-12-24, 16:24
This is a very interesting project. Windows 2000 is definitely a watershed moment in Microsoft's timeline, since it's when they first moved beyond DOS for home users. Obviously Windows XP gained a lot more wide-spread acceptance, but the presence of DirectX, by default, in the NT series allowed a …

Nobody else tried this with the 7543? I'm starting to go through the registers to see what I can see. - Alex
Cirrus Logic CL-GD7543 Resolution Scaling/Stretching
Posted on 2023-11-27, 05:22
I've got a Green 753 P5 laptop with Cirrus Logic CL-GD7543 graphics, with 2MB of video memory, onboard. Apparently, some laptops with this chip have video stretching/scaling support, but this particular version, though it is listed in the laptop's manual as being activated with Fn-F11, doesn't seem …

You might want to try a different output. I had to use /o1 on mine, as the primary output was mapped there, for some reason, on my Dell Latitude X300. - Alex

Re: DosView

Very cool, @SuperIlu. I wrote a Targa (old 24bit graphics format) viewer for MS-DOS 30 years ago, when I was in high school. It was a satisfying but also quite frustrating project. Maybe I should try to recreate it, one day. If I could write DOS graphics C code when I was a teenager, I surely can do …
Re: About 720K 3.5" drives for PC
Posted on 2023-11-04, 00:53
IBM used 720k floppies pretty extensively. They were available in the AT/5170, and were the default drive in the PS/2s powered by the 8086, including the Model 25 and Model 30. They were also present in the IBM 5140, and in many other early portable computers, including the Toshiba T1000 and it's …
Re: My experience with a KingSpec IDE SSD

The cheapest performant solution is to get an mSATA-to-IDE adatper and a small mSATA SSD. Those are reliable and much faster. - Alex
Re: UNISOUND - Universal ISA PnP Sound Card Driver for DOS v0.80a
Posted on 2023-10-23, 03:13
FYI, the 86box folks confirmed that what is happening is that Unisound is picking up the standalone game controller instead of the sound card. @JazeFox, any suggestions? - Alex
Re: UNISOUND - Universal ISA PnP Sound Card Driver for DOS v0.80a
Posted on 2023-10-22, 06:12
I've been using and enjoying Unisound for some time, but I discovered an interesting weirdness with 86box. With (at least) 86box v4.0.1 (and the latest beta), and Unisound v0.80a, when I attach a joystick to an emulated card (tried SB16, SB16 PnP, and Crystal CS4236B), Unisound stops detecting the …

What other memory managers have folks used, rather than jemmex? Do we have a way to report success or failure, i.e. a pinned post? - Alex

As far as I can tell, neither of those games has a command-line switch to force SB recognition. - Alex

Thanks again for this great work @crazii and @thp! I have been experimenting with this on a variety of ultraportable 4:3/5:4 LCD P3 and P-M laptops, since they are a heck of a lot smaller and lighter, and have much better quality TFT displays that earlier machines that have real SB-compatible audio …
Intel 830GM Graphics and DOS Gaming
Posted on 2023-10-02, 18:44
I picked up a P3-based Dell X200 recently, and it has a nice 1024x768 screen, and reasonable performance. With crazii's AC97 SBEMU, it could be a great DOS gaming laptop, except that the i830 video doesn't seem to do all the standard video modes very well. For instance, Epic Pinball looks fine on …
