Re: Using an ISA VGA card on an AVR

Posted on 2023-09-24, 15:19

Hi @manawyrm! How is this project going? I have been playing with the CH367 development board and the Arstech USB2ISA adapter. They both seem to work to some extent but the software is absolutely awful. The Arstech adapter seems quite nice from a hardware perspective but all the source and drivers …

Re: SBEMU: Sound Blaster emulation on AC97

Posted on 2023-03-05, 21:36

Hi, I'm happy to announce that SBEMU is ready for more tests. :D Purpose: for PCs with AC97/Intel High Definition Audio sound cards that doesn't have Sound Blaster support (vintage PCs after 2000 era, or modern PCs with HDA). Supported PCI soundcards: Intel ICH nForce (nForce boards not tested so …

Re: Radeon X800 - no DVI output in DOS?

Posted on 2022-04-10, 12:59

Are all the monitors on which the x800 does not work in DOS capable of resolution/refresh rate combinations that exceed 165MHz in terms of bandwidth ? My guess is that there is a potential issue with the logic in the x800 BIOS not being able to deal with resolutions in the monitor EDID that require …

I had tested this on 2 different PCs with a BenQ 1080p panel However I just switched to a different monitor (1440p Viotek panel) and it works! Is there something "off spec" about the X800 DVI signal that makes it work with some monitors and not with others? What motherboard/platform you have ? What …

Radeon X800 - no DVI output in DOS?

Posted on 2022-03-19, 14:56

I have two ATi Radeon X800, PCI-e variant Neither of them will output video signal via the DVI port (“no signal”) until Windows starts. So with a single DVI cable connected, the experience is: 1. Turn on PC 2. “No signal” 3. (after 15-20 seconds) Windows desktop appears The VGA port works fine. I am …

Re: Replace fan for Radeon X800 XL?

Posted on 2022-03-15, 03:51

Those replacement fans are quite expensive, given you can find one at all. I was looking for some for myself but found it almost impossible to source one since they are mostly long end-of-life and hence unobtainable. This for example is one of an ATi AiW 9600 card I have: https://www.mouser.de/ …

I recently acquired this Radeon X800 XL: Filename radeon_x800_xl.jpg File size 373.32 KiB Views 1364 views Unfortunately the bearings on the fan are gone. Even after several applications of oil, it still makes a loud grinding noise. Any suggestions on a replacement fan or cooler? Thanks in advance! …
