Hey,
I know this is like kicking a dead horse, but listen to this one.
I had a full MDK 9.1 installation on a Tyan 2090 i845 Trinity M/B with a P4/2.0 CPU, GF4/4600 with the latest NVid drivers. Worked fine. I then upgraded the motherboard 3 days ago to a Via P4PB-FL PX400 chipset (built-in firewire, usb20, sound, lan) and 256MB of Kingston DDR/333MHZ/2700 ram.
WIthout doing 'anything', I booted into Mandrake, and except for the boot going a little slow for 'new' parts discovery, it worked great. Everything worked, and I didn't have to do a thing. I sat there amazed. I didn't believe it at first, but then went to X11 log file to make sure AGP was set to 4 and yes it was. GLX gears pegged out at 5221 FPS (fine with me). Now, I may not have ATA133 or AGP8 (because I don't have the equipment yet), but I'll tell you what, when I tried this doing the Win2K on the other hard drive, I had to jump through hoops to get Win2K to boot again. I had to make the box stupid again, and use windows setup program to 'update' the box (which really means make it stupid again), meaning after the upgrade I had to download mucho megabytes from MS to get everything working again.
But Lunix worked out of the gate, so sweet.
I just had to share this one.
