Celeron 566MHz ATX Tower
This time not an Intel, not AMD but Cyrix, or VIA.
This is a computer from 2000 with Cyrix CPU. These CPUs were low-cost,
low-power and despite their high frequency (this one is a Cyrix M3 with
550MHz clock) they had poor performance. This Cyrix is comparable to
These CPUs were bought because their frequency looks good in advertisements. In fact they were not so common and although most VIA chipset based mainboards support them, it is not widely marked in most manuals.
The machine has a typical configuration for these times: 128MB of RAM, a 2x AGP graphics card and 8GB hard disk of popular Seagate Medalist series. Additionally there is a network card and, what is not so typical, a video capture board, a bit older than PC.

The mainboard is very "smart", it detects most problems
and informs the user. It is possible to change front side bus frequency
to overclock CPU, but RAM goes upward with it.
The settings for RAM like "Normal, Fast, Turbo, SDRAM 8ns, SDRAM 10ns" seem to have no effect on preformance.
The video capture board, MiroVIDEO DC1, is an older one
with a MJPEG encoder. Video coming from it has no high resolution, but
sufficient for occasional ripping VHS. It requires a special istallation
in Windows 98.
First, install the OS and the system. Now install the board and check does the computer start with it. In the system, it won't be detected as it's not fully plug-and-play compliant (this board has been introuced in 1994 and was in market until 1990s). Go to Control Panel, then to Add New Hardware wizard and then instead of scanning for new hardware select the option to choose hardware from list.
Select "Sound, video and game controllers", go next and "Have disk..." selecting driver directory. Here, install the driver. The driver installer on floppy is for Win3.x only.
Now the most important part: The system will show you 3 settings, IRQ, DMA and address, write them down to paper. Windows will shut down to let you install the board but you previously did it.
Turn the computer on and enter BIOS Setup. Go to PNP/PCI Configuration and set the following options:
- "PNP OS Installed" to "Yes"
- "Resources Controlled by" to "Manual". You will get lots of IRQ/DMA options below.
Now change the IRQ and DMA you written down to "Legacy ISA" leaving all other ones to "PCI ISA/PnP".
Now you can use VidCap or FlyCap to capture video without "Bad IRQ" error. Overlay will not work anyway. About overlay connector, I still don't know how to connect it.
Manual and drivers for mainboard are still (2017) offered by manufacturer.
