RT2000 sharing same IRQ as my SBLive...

[Case]

Hi,

I have a problem with my new RT2000...it shares the same IRQ as my SoundBlaster Live! card (IRQ9). Can I change this manually?


When my SBLIVE! is installed, no picture shows up in the capture window in Premiere, and no sound from the videodevices is heard either... Firewire, composite or S-vhs, it's the same.
If I take out the soundcard, then the RT2000 capture works great. I tried moving the soundcard to another PCI slot, but the two cards still share the same IRQ...
Please help!

Depends on the type of motherboard you have, you can actually set the IRQ in the bios manually.

It's best the RT2000 doesn't share IRQ's with the Live.

Ellie,

I have an Asus K7M motherboard with an Athlon 650mhz CPU.

The SBLive! settings are greyed out in the bios, so I can't change it.

Would a new bios driver help?

Thanks,
Kasper

The K7M's manual tells you exactly which PCI slots (and AGP) share with one another. If I remember right it is as follows;

AGP, PCI1 & PCI5 all share,
PCI2 (doesn't share with anything)
PCI3 shares with onboard audio (if enabled)
PCI4 shares with USB
PCI5 (as PCI1)

Damnit, another hard drive failure.....

Huh... I don't get your point really...
There's nothing bad in sharing IRQ.
That's a modern method to use a lot of
peripherals without having to own more than 1 PC.
Personnnally, my RT2000 shares its IRQ with
my SBLive, the SCSI shares its IRQ with the 1394, etc !

I know that some sharing cannot work. Some say you can't share 2 I/O cards....blah blah !

Sure if you want something else, it will be tough, but, believe me, _everything_ works on my computer on this IRQ sharing basis....

Actually, it works now. I moved my PCI card around a bit.

Previous setup:
PCI1: RT2000
PCI2: Encore DVD encoder card
PCI3: SBLive!
PCI4:
PCI5:
ISA1: Scanner card.

Current setup:
PCI1: SBLive!
PCI2: RT2000
PCI3: DVD encoder card
PCI4:
PCI5:
ISA1: Scanner card

This setup works fine.

I have another problem now, though. Actually, I have 2:

1. When I grab footage using the DV cable, sound becomes distorted, some kind of jerks, but very fast ones (20 jerks a second or so)Original sound is barely audible. It works fine when using composite, so it's not my system running slow.

2. I just installed a new harddisk. An IBM GXP34 20,5GB harddisk. It writes allmost 30MB/sec, but only reads 2MB/sec in single stream and even slower in dual stream. IDE drive setup:
PRI Master: Seagate 4,3GB, system drive (WIN98)
PRI Slave: Creative DVD-drive
SEC Master: IBM GXP34 20,5GB ATA/66 (the one with the problem)
SEC Slave: IBM Deskstar 10,1GB ATA/33

My other IBM harddisk actually read much faster than the new IBM at the moment!! I tried 3 different IBM GXP34 20,5GB harddisks, with the same problem.

My system:
ASUS K7M motherboard
Athlon 650MHZ CPU
256MB PC100 ram

Please help me with this prob... and thank you all for help with my previous prob, which opened up for new ones

Have you tried to force the drive to UDMA33, and checked it's results?

Damn, it worked! Thanks!

It now writes 27MB/sec and reads 21MB/sec single stream.

But why is this? As far as I know, Asus K7M supports ATA/66, so why do I have to force it to run ATA/33? Would it read/write even faster if it worked in ATA/66 mode? Could it be the cable? Do I need a special one for running an ATA/66 harddisk? Or should it be able to run anyway? And if I do need another cable, will I be able to run a slave ATA/33 drive as slave on the same cable?

Regards,
Kasper

P.S. Anyone have a solution to my other sound problem? It's very annoying, because the audio grabbed with the DV cable is practically useless... and I can't grab DV video and composite audio at the same time. If I need the audio, I have to compromise on grabbing the DV video through composite, which sucks, when I have a compatible DVcam.

[RoGuE]

If connecting a ATA/66 drive to a ATA/66 interface, you MUST use ATA/66 cables, i.e 40-pin connectors, with an 80-conductor cable.

[Case]

Ah, that explains my first problem, thanks! I'll go and buy a new cable right away! Will I be able to run an ATA/33 harddisk as slave on the same cable?

Has anyone got some input on my other soundproblem? Am I the only one experiencing this?

Regards,
Kasper

Glad to have helped!

Yes, you should be able to run your UDMA33 drives on a UDMA66 cable. It's supposed to be backward compatable. I haven't tried it myself.
