I need help with an IRQ conflict under Win XP

By twilazoned ·
I am trying to help a friend who is 1,000 miles away and totally computer illiterate, and would really appreciate any help with this problem. He needs to add a I56LVP-F1 - CTX 56K V.90 PCI MODEM. The problem is that when he installs the card, boots the pc, there is no monitor. When he removes the card and reboots, it goes straight to bios where he gets a "boot hung for improper cpu speed setting, pc will start in safe mode". The cpu is set correctly. He is running an ASUS mobo ps4800 with a Award medallion bios 6.0. ACPI BIOS rev 1009. This happens regardless of the PCI slot he puts it in. I had him change from ACPI to standard pc, but it didn't help. What now?

OK I know that they are more expensive

But maybe in this case a Hardware Modem rather than this software Modem might be a better choice in this particular application or even an external Modem.

some ways i have dealt with similar problems

by sgt_shultz In reply to I need help with an IRQ c ...

now you know why they call it plug and pray
1) if there are ANY cards that can be removed (such as NIC, sound, infrared etc) try taking them out then putting modem in. XP might assign resources differently.
2) might want to try forcing irq assigmment to the pci slot in bios (are you sure it is irq not io address conflict?)
3. if the thing has dos drivers you can set them up and force an irq that way. won't apply in your case though, pretty sure.
4. modems are so cheap, might want to send your buddy another one to try. ditto video card...

any more suggestions?

1) he had no other pci cards, but I did have him try the modem in each slot, to adjust for the irq's.

2) I can't force the IRQ's in BIOS, although I did try to change it in the device manager to standard pc. Thanks to microsoft, that allowance is no longer made. If there is another way to force them, please let me know.

3)number three doesn't apply

4) he's 1,000 miles away and the card could have been damaged during shipment, or since it was 10 degrees and windy, and he came in and ripped into the package, he may have had some static that zapped the board.

I really appreciate the help. By the way, is there an easy trick to revert back to HAL after changing to Standard pc?

Well if it is an IRQ conflict

by HAL 9000 Moderator In reply to any more suggestions?

You should be able to set the available IRQ's in BIOS instead of leaving them on Auto. But you need to know what it is you are doing here or you can make a bigger mess that what you started with.

I've found quite a few Plug in Cards that are simply not compatible with the M'Board Chip Set so if the system is running properly without the Modem Card I would put it down to the Modem Card being incompatible with the M'Board Chip Set. I've seen examples of this on new AMD M'Boards where the Video card is just incompatible with the M'Board ans stops the system from doing anything at all then you can buy another Video card with the same Chip Set but from a different maker and it works perfectly. Makes it kind of hard to explain when both parts come from the same maker and don't work but a cheap brand Video card will work.

Even on Intel Chip Set M'Boards the BX440 Chip Set with a RAID Adaptor slot will not work with some add in cards TV Capture Cards are the most common but there are some others which will just cause the system to lock up and never boot no matter what you do, these Chips Sets just don't work together no matter what is tried and you are only driving yourself nuts trying to make them work together. This is hardly a new problem as it was very common in the DOS days where you could buy the same brand Video card from different shipments and one would work and the next one wouldn't work. It was a nightmare back then but not so common now but it does still happen occasionally and more so with AMD M'Boards with NVidia Chip Sets.

I appreciate the help. I got him straightened out. The majority of the problem came from not knowing anything about his pc, and with him being 1000 miles away and unable to connect to the internet, it wasn't like I could take a quick peek to see what was what. (He had bought one assembled by a friend of a friend of a friend...) I think there should be a banner for newbies on their desktop proclaiming "STOP where you are and make a copy of your System Information because you WILL need it later!" Just finding out the motherboard was a monumental undertaking.

Again....
Thanks...

you mean besides different modem? (rdl)

by sgt_shultz In reply to any more suggestions?

I have forced legacy cards to the io and interrupt i wanted by using the dosmode drivers and creating autoexec and config.sys and loading them there. If windows sees that it will assign the same resources. but yours may not have that capability.
hence my not so tongue in cheek recommendation to try another modem.

I appreciate the help. I got him straightened out. I hadn't thought of the dosmode idea, but will keep it in mind.
