I'm evaluating an old system that my neighbor gave me. It has an AOpen s651m motherboard which has the SiS651 chipset. The system currently has Windows XP on it, but I think this system would be prefect for Windows 98 with a 2.0Ghz Willamette or Northwood based P4. However, I'm having trouble finding reliable information as to whether there are Win9x drivers for this chipset. I see where there are video drivers for the integrated graphics, but I wanted to make sure before I start reformatting.

Hi.

Is the current WinXP install of your own or did it come with it when you first got it?
In case of any doubt, it could be a good idea to use a different HDD for your 9x install, so you won't need to actually delete your existing XP install.

I'm not familiar with that particular chipset. Iirc the most recent SiS chipset I ever used was either a SiS530 (which is a ss7 chipset) or a sA SiS system that I build, but did not own (build it for someone else using parts that were not mine).

Given the age, one could assume that 98SE does not have the chipset video drivers internally, but you should still see an image. And if worst comes to worst, you could always add in a separate display adapter and either ignore or disable the onboard one.

Older Tom's Hardware reviews suggest the chipset is supported under 98: https://www.tomshardware.com/reviews/integrat … nce,674-11.html

There are IGP and IDE drivers for this chipset for Windows 98 still on SIS site. http://w3.sis.com/download/
Try to install them and see what happens 😀

Thanks! I'll give it a shot on another drive.

The motherboard has a Celeron D 320 on it, which might be quite good for Windows 98, but it feels a little sluggish with Windows XP SP3.
