Wow! G400 and SBLive! now uses 2 separate IRQs.


I moved SBLive! from PCI slot 5 (farest from AGP) to PCI slot 3,
and moved VooDoo 2 card from PCI slot 3 to PCI slot 5 (farest from AGP),
without reinstalling drivers.
After reboot Win98SE has detected card swapping and reassigned all IRQ/DMA.

SBLive! used IRQ5 and SB16 Emulation moved from

PORT: 220
IRQ : 5
DMA1: 1
DMA2: 5

to

PORT: 240
IRQ : 9
DMA1: 3
DMA2: 7


...BUT...

SB16 Emulation doesn't works because (and this is a problem of my SB16 too!!!)
any Creative soundcard doesn't works with IRQ 9!!!

...NOW...

Setted "Allow LPT Interrupt Sharing" ON! and SB16 Emulation moved to:

PORT: 220
IRQ : 7
DMA1: 1
DMA2: 5

and all seems works well!


I don't see any problem with my HP Deskjet 720C (that share IRQ 7 with SB16 Emulation),
and i dont think to print anything while using latest emulator under DOS7.... http://forums.murc.ws/ubb/smile.gif

(Hope this letter can helps somebody!)

Actually, my Creative SB Live Value works perfectly on IRQ 9. I don't know why you would be having a problem with it. ANyway, it doesn't seem to matter now that you have fixed the problem.

I'm glad to see you got your IRQ's fixed. I though swapping cards would do it. Sometimes you just have to try several combinations.

I am curious, why doesn't the VooDoo 2 card show up in the IRQ list? I've never had a VooDoo and this surprised me. Also, are you using an external modem to get to this forum because there is no modem in your list either.

DooDoo 1's and DooDoo2's don't need IRQ's.

CMag:

SBLive! works with IRQ 9, but Creative SB16 Emulation (like SB16 original doesn't works)
You can try it with FastTracker 2 under DOS, after 1 or 2 seconds playing stops...
