Shuttle AI61 problem

[RBC]

My problem is this: The system works fine with just the sound card
and video card installed. As soon as I install a modem, the sound
card, the video card and the modem get pushed on to IRQ 11 and then
stablity goes all to hell. The configuration are as follows:

1. AI61, flashed to most recent bios.
2. Win98 SE, with most recent AMD drivers installed (all three)
3. Diamond Viper 2000, set to 2X AGP setting (also flashed to most
recent bios) using most recent S3 reference drivers.
4. Vortex I sound card with AMD optimized drivers
5. T-Bird 900
6. 2 different PCI modems - a CL modem blaster, DI3635 (system won't even post with this one in); and a
Eigercom MM9050, (it works but system crashes a lot). I also tried an external USB modem (A boca b100) but
it would crash the system every time I tried to disconnect (this is a
different problem as it occurs on every system I've tried this modem
on).

Before adding the modem, my video card is on IRQ 11 and my sound card
is on IRQ 4 or 10, depending on what slot is used. System was very stable as judged with starcraft, shogun and battle realms all running fine.
After adding the modem and everything goes to 11, and the games listed above start crashing randomly, either to the desktop or to a black screen. I tried all different combinations of PCI slots for the sound card and
modem. I tried installing the modem first then the sound card, again
no luck.

I tried an older video card, a Diamond monster fusion 1X AGP, with the
same results. In the bios I set the Init Display First to AGP, and I
set ESCD to enabled with no luck. Can anyone help with some other
ideas? Thanks!

bump for extra plea for help!

I can relate. In my AI61 system, I have a NIC, a GeForce2 MX200 video card, and Soundblaster Live 5.1 MP3+ . The NIC is in the first PCI slot (the one next to the AGP slot), and the Live is in the third PCI slot. The NIC won't work in any other empty slot. I tried adding a modem (as a backup to my cable connection), but it wasn't recognized by any of the three empty slots. I basically have 3 PCI slots that can't be used. Don't know if it is a motherboard problem or that the slots share IRQ's. I've tried manually setting the IRQ's in the BIOS, but that hasn't worked either. It's a good thing everything works fine for me as is, but I will never be able to add another PCI card if I need one. Looks like it's time for an upgrade. Good luck solving your problem.

Thanks for the reply, at least by knowing someone's had the same problem as me I'll stop driving myself crazy trying to fix it. Looks like I'll have to find a cheap, ext. serial modem.
