I have 2 mod Iopeners that I did myself. Added a 6 gig HD to each, a Tennmax fan to the factory CPU, and flashed the BIOS via BadFlash. I then installed Win98 fresh on the first one and installed all the appropriate drivers so everything including sound is working great.
But if I leave it on overnight (or extended period of time) I get the Win98 'Fatal Exception' error. It is amazingly slow and extremely unreliable. I copied the first hard drive to a Ghost image and then to the other hard drive. And I have the same problem on the second one. So I connected a parallel port CD-Rom drive to it and tried installing Win2000 Professional. It didnt even make it through the installation process before crashing. So I tried again and it crashed again in a differnt spot.
Finally after a thrid time, Win2k installed but it crashes after the desktop comes up.
I do have another one running Win98 & some mapping software at a friend's pizza restaurant and he has not reported any problems or crashing----I built it identical to the two with problems. I have another one in the box and until I figure this out that's where its gonna stay.
Any help is appreciated.
