Can't change IRQ's in win98 on Asus p5a motherboard

[fullyauto9]

Hey,Hey...i've been reading the messages you guys post and it help me out a lot. I've had a marvel g400 tv for a week now and i been having problems since day ONE..but thanks to the MURC forums (and you guys) i've finally found out my problem and of course it's IRQ related. The only thing is that i can't change on of the IRQ's on my system. I tried unchecking the auto config box(s) in the device manager and it still won't let me changed or move my IRQ's around. So..can someone please help me out again. i've updated the asus mb bios, matrox driver and the agp drivers from ali but i still can't change the IRQ's on my system. Below is a brief description of my computer and a IRQ usage summary....

Aus p5a motherboard, k6-2 350mhz 96meg ram, scsi cd-r, modem,sound card, 2-pc-dvds and 22' monitor....here a summary of my irq list...

00-system timer
01-keyboard
02-programmable interrupt controller
03-com port (com1)
04-com port (com2)
05 yamaha ds-xg legacy sound system
06-standard floppy disk controller
07-ecp printer port (lpt1)
08-system CMOS/real time clock
09-creative pc-dvd encore dxr3
09-initio inic-940 pci scsi host adapter
09-irq holder for pci steering
10-irq holder for pci steering
10-yamaha ds-xg pci audio codec
10-irq holder for pci steering
10-MATROX MARVEL G400 AGP-ENGLISH
11-diamond supra express 56i sp v.90
12- ps/2 compatible mouse port
13-numeric data processor
14-ali primary ide controller(ultra dma)
14-ali bus mater pci to ide controller
15- ali secondary ide controller(ultra dma)
15-ali bus master pci to ide controller

all suggestions are welcome of course an dwhy is the irq holder using two different irq's??

thanks fullyauto9@yahoo.com

At first glance of your IRQ list, you have more devices enabled than you have IRQs for! With an internal modem and a PS/2 mouse (?), you can try disabling one of your COM ports to free up an IRQ. (If you have a serial mouse instead of PS/2, you can probably disable assigning an IRQ to PS/2 mouse in BIOS.)

The PCI steering is mostly harmless to ignore. I do not fully understand them, but they are not real devices to cause conflicts.

On virtually every motherboard out there, some of the PCI/AGP slots are hardware wired to share resources. Usually the AGP slot and the PCI slot directly beside it are hardware wired to share the same IRQ. Some mobo manuals are much better than others for giving you a heads up as to which slots share with which others.

Once you no longer have your IRQs overconstrained, you can try moving cards from one PCI slot to another.

A 22' monitor? Geeze, that's bigger than my living room!

Ok I would suggest freeing up one of your com ports in your bios then i would uninstall your modem in device manager, then i would disable your sound device once you have rebooted and you see free irq address's just reinstall as you go!.....what i dont understand is the 2 different sound thingy's but that is why i dont have a yamaha, i would guess one is for dos mode?!

So give that a try first and then post what you have!

Cheers!

P.S. I have the same board as you and this worked for me but it took sometime to make it happen so hang in there!

Cheers!

Hey there.. I've a P5A myself on a K62 450..

Want to check on the things that you guys did to get your G400 up and working. Well, ever since seeing all that things abt bad AGP implementation on Ali V chipsets can be quiet disheartening. Going to get one of those g400 DH OEMS and see how it goes. Anything helpful whatever that I should look out for will be most appreciated..

Also, I heard that you can get some of the OEM boards with 5ns SGRAMs? On where can I check for those? Is it listed on the chips themselves? Straightforward listing? Or hidden in some batchnumber code?

Thanks.

It is very obvious if you are in the semiconductor industry.

It is plainly printed on the memory chips as to whether it is a 5ns or a 6ns part. The last bit of the second line will end with "-5" or "-6", meaning it is a 5ns or a 6ns part.

However, that might not be the whole story. Sometimes when companies have extremely good yield on fast chips, they have to "undermark" fast chips into a slower speed grade because they have big order to fill. It happens, and sometimes you get lucky. Intel introduced multiplier locking on their CPUs to try to make more people buy the faster parts instead of buying the "slower" parts and running them at the faster speed. It happens in other places too. However, the odds are slim of getting 16 RAM chips on a board that are marked as "-6"s but can run as "-5"s.

Thundrchez,

Couldnt have said it better myself!
