Hi Christian, hi everybody
Thanks to your excellent support pages, I was able to get a multimonitor system running.
About every fifth boot process, windows 98 is unable to initialize the secondary card, stalls and requires a reset.
My system runs on a ASUS P2B with Celeron 400, 192 RAM, PCI Guillemont Maxi Cougar (Riva TNT II) as primary and AGP Creative Graphic Blaster (Riva TNT) as secondary cards (for more details, see database).
I run the two cards with the latest drivers, they share Interrupt 11. Has anyone else occasional or more frequent boot problems with windows 98 unable to initialize the secondary card?
Best regards,
Thomas Weishaupt

Try different drivers (preferably Nvidia reference drivers). If this doesn't help, I would change the PCI slot of the primary, could make a difference.
I've had problems with Win98 as well, for example my Diamond Fire GL 1000 Pro doesn't work as third card, but it worked perfectly well as second. Or occasional lockups when changing display properties of my Viper 550, but this was fixed in later versions of the Nvidia drivers. Due to using mainly Win2000, I haven't further investigated those problems.

1Thanks for the advice, Christian.
After fiddling a bit further with NVidia's reference drivers, it run fine.
Still I moved to Win2000. This one's trickier, though. I can get it going stable with the RivaTNT (AGP) as primary and RivaTNT2 (PCI) as secondary. I can't setup Win2k with both cards in and BIOS boot sequence PCI/AGP. Win 2k refuses to complete the hardwarerecognition. Adding the AGP-card after a full installation wouldn't help either, win2k stalls while starting up.
I noticed though, that its doesn't matter much to setup the AGP-card as primary, I can change the setting manually while Win2k is running. While booting win2k seeks the AGP card (the first installed card) as primary always.
Do you have any idea how to script automated changes re which is primary and which the secondary on start and on shutdown?

The AGP card will always be primary during booting, this depends entirely on BIOS settings. But Win2000 should automatically set the PCI card as primary when booting is finished, just as you have specified in Display Properties. Seems like Windows doesn't remember your settings.
You can't use a script to change the primary monitor, this functionality isn't directly accessible to scripts. But I guess I'll add a command line argument to Multimon beta 4 to do this, shouldn't be a problem. This would allow you to change the primary monitor from a batch or script file by calling Multimon.

Hi again.
Yes, right you were, win2k didn't remember the settings using the TNT drivers that came with win2k. - With the latest drivers of Creative Labs and Guillemont, the system runs well and stable. I must say though, neither the WinTV card nor the Sigma Decoder card are in yet, the win2k for this cards drivers though look like flawless on single monitor system. (I'm a bit slow, I had to befriend with a lot a of new stuff first moving from win98, getting the burner to burn etc.)
Best regards

Just like my setup: 2 Cards sharing the same IRQ. I have sluggish performance on 3 TNT cards and if I whip things around real fast, the windows becomes hopelessly scrambled up, as well as the occational lockups. I can't seem to force seperate IRQ's on my SOYO-4 MoBo, this has to be the cause of performance and stability problems. Any ideas?
Thanks.

Update - I found a bios feature called "Passive Release" in my Award bios. When I dissabled it, the lockups and window scrambling stopped. It seems bullit proof but video is still sluggish. If I drag a large window quickly across the monitors, 20 or 30 duplicates are made in its wake and take 2-4 seconds for them to disappear. Does a dual head card have this same characteristics, or are they much quicker?
