Maxi TV video + Ethernet + win95 OSR2

Hi, I've installed win95 OSR2 and new problem appears.
I have two cards TVvideo Maxi PCI2 and Ethernet who use the same IRQ (12). When I install the TVvideo Card, it works fine, but when I stop the pc and start again, the system blocks... I must re-install this card to work correctly!!
And so on...
This problem was not on win95 ORS1 (and the IRQ was the same, 12 too).
I don't understand. Do I can change the IRQ (and how?)? Is there an option on the bios setup ? ...
Thank you.

Yes you could change the IRQ on any of them.
I will lock the question,because some people come to block the question with useless answers that we call (BOGUS).

Could you give me more details about your system, BIOS specially and if these 2 cards are PNP or not.
Also if you received any disks with these cards, specially the ethernet card, it should be jumperless and IRQ software configured.  I would recomment IRQ10 for the ethernet card.

Before we do any changes too, I would like you to check for free IRQ in your device manager and post them here as well.

I will wait for your post and then will give you a step by step procedure.

Regards

Thank you for you answer's begin !

PCI Ethernet adapter PnP.Driver:RTL8029.SYS. I don't know how to change the IRQ (the doc says that win95 make this automatically).
In the hd, with the install's files, I have NTRT.INF with lines :
[*rtl8029.LogConfig]
IRQConfig=3,4,5,7,9,10,11,12,15
IOConfig=20@200-FFE0%FFE0(FFFF::)
I could, perhaps, reinstall the card and leave just
 IRQConfig=10, to force win95 with this IRQ for Ethernet card ??

TV Video, PCI, Pnp. Many drivers, but no util to configure the IRQ, too.

ASUS P/I-P55T2P4. The doc sepcifies that "make sure that no 2 devices use the same IRQs...(!) [...] An IRQ number is automatically assigned to PCI expansion cards[...]To install a PCI card, you need to set something called the INT assignment. Since all the PCI slots on this motherboard use an ITA#, be sure that the jumpers on your PCI cards are set to INT A."
I don't understandthis last line.

Thank you very much for help,

O.K. info is fair enough for now, and this is the first option I want you to follow to attempt changing the ETHERNET card IRQ:

1) On your desktop, right click on My Computer
2) Selcet properties from the pop up menu
3) Click on the Device Manager Tab
4) Click on the little + next to the Network Adapters
5) Click on the ethernet card RTL
6) From the lower left part of that window, click on    the properties button
7) Now click on the Resources Tab from the new window
8) Here you would see the IRQ beeing used by the card which in your case would be 12, and in the lower part it would say conflicting devices and listing most likely your TV card.
9) Now click on that Interrupt Request
10) Now UNCKECK the box "Use automatic settings" if checked
11) Now click on the "Change Setting" button
12) Here in this window scroll the the number 10
13) Click on apply, here please while changing the numbers look down to check if on the IRQ10 there is noo other conflicting devices (JUST as a double check)
if the message "No conflicting devices" is still displayed, we are in business.  Now hit the apply and O.K. the whole way

Normally you should be prompted to restart your system, that's fine accept it.

Once your back in windows, I want you to go the same way from steps 1 to 6 and verify if the card held the NEWLY assigned IRQ or not.

Let me know how did it do up to here.

Thank you,
BUT,
I knew how to change the IRQ from the Device Manager... However that's why I say that win95 think that there are no conflict!
And, I cannot change the IRQ (windows'message).
I see that the IRQ for the 2 cards are 12, Win95 know it, accept it, and work normaly since I re-start !
So, my question is How change the IRQ
-before run win95 (perhaps in the bios?)
-or other that the way Device Manager...(directly in Register?) ?

Thank you.

What you may do here is to get in the BIOS and Check your PCI cards slot order.  Of course I can't see exactly what you see because I don't know which BIOS do you have.

There you can force the First PCI slot to use a specific IRQ, (e.g.: 11) then the second PCI slot will take the next available IRQ.

Update me on your BIOS, please.
Something else that you have to check, is 16 bit device drivers. In Windows first release they took in consideration teh 16bit devices drivers, an option that have been eliminated in OSR2.  This is also why you may experience a conflict.

I hope not to be facing the same problem I have with one of my clients.  Same thing at boot, (Sharing the same IRQ), we have change everything possible (conflicting cards are:Video & Adaptec) sitting on IRQ12.  No matter what we do, no way to change that.  Changed his tape backup 3 times different brands, without any success.  We have used another Adaptec card where we jumpered it at IRQ9 and at boot still is seen on IRQ12 as the video card.

If this happen, with you, it might take sometimes before I could have answer for you, which will make me feel very bad to have collected your points without providing the needed help.

Let me know what happened
Regards

Hi,
I asked the problem to guillemot and here the answer :
"Un plantage de l'ordinateur avec cette carte peut provenir de deux endroits :
- Conflit d'IRQ. Dans ce cas changer de slot PCI, la TV Video PCI ira se loger sur une autre IRQ
- Faites une mise à jour des drivers de votre carte graphique (Drivers DirectDraw)"
The second point was not interessant because I tried all drivers versions... but the first was THE response !
I have change the TVvideo card of his slot. Nothing maters... but I insist and change the 3 PCI cards (with the graphics), and now, the ethernet is IRQ 11, the 2 others cards 12. There is always a conflict, but this time it is supported by windows 95!
So, can we mean to the change slot to attribute a different IRQ... directly !
Thanks,
bye.
