Home / I-Opener Areas / I-Opener Technical Stuff irq shared by usb and video, I AM PULLING MY HAIR OUT! tryin to free up irq sharing between usb and video

irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) BigTex Profile Hoping to enlist you pros. I am having horrible time trying to get my raylink/buslink wireless network to work reliably. It is slow and crashed the system often. Works great on all my machines but iopener. Only thing I can suspect is an irq sharing of the usb and video device driver. I have gone into the bios and tagged the offending as legacy/isa, and tried all combinations of disabling usb and video irq's, but everytime they pop back up, they are still sharing the same irq. I have successfully gotten them to both share irq 10,14,11 but I cant seem to separate them. any ideas? HELP! 01-09-2001 21:59:25

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) BadFlash Profile | Email Have you set up the IDE to be a single channel? I was having lots of problems with my I-O's until I figured that out. Click on the hard drive controller in the device mangler and fix it if you haven't. 01-10-2001 06:46:20

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) BigTex Profile Yes, I did that. It kept ide from sharing the same irq as video and usb, but still have those two devices on the same irq. jason 01-10-2001 10:31:26

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) mp3boombox Profile | Email I'v got 4 irq's free and my usb/video share the same IRQ but i dont have any problems period? 01-10-2001 14:44:22

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) Johnson Profile I've been having the same problem.... someone told me to kill the cmos and have it refind everything and reassign the irq's, but noone told me how do to it... I have a little proggie called killcmos, but I'm not using it until someone tells me how to... if you want to screw with it, drop me an email and I'll send it to you. jackson_1@hotmail.com 01-10-2001 15:54:04

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) Programmer Profile Set EVERYTHING to legacy set reset config data to yes reboot set IRQ15 to PCI/PNP set reset config data to yes reboot * as of now IRQ 15 should be sharing the Primary master and USB Set All IRQs to PCI/PNP reboot *Make sure there is an IRQ free set IRQ15 to PCI/PNP set reset config data to yes reboot *USB should now be on an available IRQ 01-11-2001 15:22:18

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) YouBecha Profile I just noticed that mine shares the USB and Video, IRQ 11. Is there a gain to be made by giving them separate IRQs? http://www.geocities.com/mr_bubba_zanetti/ 01-11-2001 16:52:53

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) ckbone Profile I also have been unable to separate the USB and video IRQs. I tried the just mentioned technique without success. It is possible, not yet proven, that a separate IRQ for the USB, would improve USB performance.....perhaps making USB LAN connections faster, and more stable. It's worth a try. If anyone is successful, please post exact details. 01-11-2001 17:15:00

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) sodmeister Profile I tried this and it worked for me. The USB showed up on IRQ15 and the video was on IRQ 11. I haven't done enough with the networking to see if it's better (more stable or faster), but at least it's nice to get the system to not share the IRQs anymore. Thanks for the info... sod ( "The lunatics are on the grass..." ) 01-12-2001 08:46:00

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) Programmer Profile Sod: make sure to push the USB somewhere else, it does not belong on 15 CKBone: the problem is basically a broken bios, you just need to trick it into splitting them apart first, then make them go where they belong one by one.. it may require a lot of reboots, and make sure to set reset configuration data each time. 01-13-2001 16:18:27

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) sodmeister Profile Programmer- Thanks for the warning about USB at IRQ15. I haven't experimented much with this, but it does "seem" to be OK at IRQ15. Typically, 15 is used for the secondary IDE, which doesn't exist on an I-opener. I booted up both Windows98 and Linux without incident. It could be a real problem for an initial install of Windows, since it defaults to both IDEs on install. BTW, I feel you're being far too kind to Award by calling the I-opener BIOS "broken". I have 3 desktop machines with the Award BIOS, and they all have the same (very retarded!) way of assigning IRQs. I've got USB sharing with my video and my network sharing with the sound card on one machine. What's wierd is it actually works, at least for a while. I can play Unreal Tournament locally and all seems happy. I do have to reboot occasionlly, though... sod ( "The lunatics are on the grass..." ) 01-13-2001 18:15:31

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) ckbone Profile I worked at this four hours last night, and I was never able to separate the USB and video IRQs. If it makes any difference, I'm using a Badflash BIOS (got it in April) on a V2 with a Winchip2. I tried the mentioned method many times, with and without enabling an IRQ for the video and USB. Booting with everything "Legacy" leaves the video and USB on IRQ15. I can change this to several other IRQs....but never separate. Do you think my BIOS version from Badflash has anything to do with it? Has anyone found any real benefits to a separate IRQ? Except for a disappointing USB performance, unstable USB LAN operation, everything else works ok......Is all this trouble here worth anything? 01-14-2001 05:11:09

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) Programmer Profile personally I don't even know of a reason to have video IRQ enabled at all; many of the problems you are having with USB are likely to be related to either 1) irq interference or 2) a buggy usb implementation that does not verify that it has enough bandwidth ( download the filter driver from via) 01-14-2001 09:30:12

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) cheaphack Profile I have also tried to follow Programmers instructions but failed. I have one question, though, and that is the second sequence of steps: > Set All IRQs to PCI/PNP > reboot > *Make sure there is an IRQ free > > set IRQ15 to PCI/PNP > set reset config data to yes > reboot > *USB should now be on an available IRQ Shouldnt IRQ15 (in the last step) ALREADY be set to PCI/PNP from the third step? I did the above steps and could clearly see the Cyberblade and USB migrate to IRQ 10 or 11 (to the same IRQ) and when IRQ15 was made available again, they both migrated back to IRQ15. What is it that should make one stick on the open IRQ? (in my case, there is an open IRQ at 10 after all is said and done). -- cheaphack 01-14-2001 12:33:54

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) mp3boombox Profile | Email Ok programer, I just came up with the perfict USB/VIDEO irq fix. You ever used the bios backup program which saves all your BIOS settings EVERY THING. Then restores them if you need to. Why dont you download one of them programs make a back up of the BIOS settings and make it avalable for the rest of us. Granded this may screw up some peoples install's of windows due to irqs posibly being changed BUT hay if it fixes it in the long run its more then worth the effert. Both my friends have DELL computers ( :p ) and i cant seem to send files to them using my USB EITHER net adapter when i drag my IO over to there house to do some gaming, YES i game on my iopener. hehe doom2-duke3d-shadow warrior. and as soon as i get my k6-3 450 installed we'll do redneck rampage also. hehe its funy why not. But files seem to degrade as there being transferd and my other friends computer i just get constant packet crashes. But i use my home network or an other friends high speed network and There are no problems? I think it has something to do with sharing the IRQ. I can deal with reinstalling winblows if it makes it so that i can work my io on any network perficlty. http://members.panax.com/bachh/ My EZnet 200 tower, hacking page. 01-14-2001 13:24:09

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) asm_ Profile Hi, If you don't care if the iOpener's video card use a IRQ or not. I have the following solution for you. This solution has been test on WinME with V5. However, it should work with Win98 and Win98SE too. 1. Enter BIOS and disable Assign IRQ to VGA. Notice that you can have the PnP Configuration Setting in Auto or Manual. It does not matter. However, If you don't want USB to use IRQ15, set IRQ15 to Lagacy. 2. Reboot and Open device manager in the System properties. 3. Expand System Devices Branch and look for PCI Bus 4. In PCI Bus Property, select "IRQ Steering". Disable IRQ Steering by deselecting "Use IRQ Steering" check box. 5. Reboot, now your Cyber VGA should be off your IRQ list. 6. To test if the network connection is now stable: Remove TCP/IP and Install NetBEUI and transfer a ZIP file that is at least 700MB, then use "pkunzip -t *.zip" to test the integraty of the file. The reason for using NetBEUI is because it is the least stable protocol. Therefore, if there is any problem on the transmission, it should reveal quickly. For those of you who are going to try this, please post your result here. When posting, please including the type of USB NIC, OS Version, iOpener Version. I have tried this solution with TCP/IP, IPX/SPX and NetBEUI on two different NIC. The following are the result. DLink (Clear) *TCP/IP: Completes the Transfer and CRC verified. However, massive collision occured while transfering. (~30 minite) *IPX/SPX: Completes the Transfer and CRC verified. (~40 minite) *NetBEUI: Fail the test twice at about 90% 3COM *TCP/IP: Not yet done *IPX/SPX: Not yet done *NetBEUI: Complete the test and CRC verified. (~45 minite) I like to point out an interesting fact that 3COM is actually 50% slower then the D-Link. I had to pay almost 5 times as much for 3COM. :( ~ASM 01-14-2001 13:36:02

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) ckbone Profile The just mentioned method worked for me....no IRQ for the video and IRQ 11 for the USB. However, my USB LAN still crashes (Warplink wireless). FWIW..The USB drivers on the VIA website are supposed to be for Win95b only. Is there some utility that can measure USB performance? 01-14-2001 18:03:14

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) cheaphack Profile I just tested the "get rid of pci/irq steering" idea. While it did get rid of the IRQ sharing between USB and video on IRQ15, it made no difference in throughput. With a Linksys USB10BT: * BX(10/100)->Iopener(USB10BT): it took 12.25 minutes to transfer 266MB across my 10bT network with the "no pci steering" *BX(10/100)->Iopener(USB10BT): it took 12.17 minutes to transfer the same amount of data with the shared IRQ. * BX(10/100)->815e (10/100): two systems containing Linksys PCI 10/100 cards connected through the same hub on the same network transfered the files in about 5.75 minutes. *Iopener(USB10BT)->815e: 17 mins (IRQ steering enabled.) This is not meant to be scientific... just to establish some kind of baseline throughput numbers to see if prohibiting irq sharing with USB helps at all. 01-14-2001 20:44:20

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) redwood Profile ok, see if this finally posts... grrr , well, glad to see others having USB networking problems... woops, no, I mean, glad I'm not the ONLY one fighting this.... :) this site http://www.speedguide.net/Cable_modems/cable_irq.shtm has an interesting fix, harmless, worth a try... easy to reverse.... while there, backup to the Home page, looks like Alot of good info... I'm _currently fighting IRQ problems on my desktop machine, thanks MSFT, with plugNpray I nolonger have to set a jumper, making my computer do what I Want.... 01-15-2001 07:15:56

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) mp3boombox Profile | Email Programer could you use one of them bios back up programs, and make a back up of the bios settings and share it. That would be a lot easyer then having 16 zillion people try to fix there IRQ problem and end up screwing there windows install due to throwing there IRQ'S all over the place TRYING to get the usb/video to devide. This would make life much easyer. I'v tryed with all my iopeners and have YET get them to devide. I can change what irq i'm using but seperating them hehe thats an other story. 01-16-2001 04:17:59

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) Programmer Profile If I get a chance tonight, I'll grab the image and put it up.. .. this is a problem that I never had (on 3 ios) so it's interesting to see so many with it.. 01-16-2001 09:10:06

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) mp3boombox Profile | Email I wonder whats causing the problem in the first place? also i do wonder what most IO's are set as orignaly irq setting wise? It could be that a few in how every many batches have the bad setting??? but then again who know's. It could just be winblows screwing things up also on the first install. Hum programmer seeing as how you never had the problem on 3 io's did you have some settings turnd off in the bios like asign certian irq's to XXX devices? i.e. video/usb?? makes me wonder? 01-16-2001 15:41:05

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) BigTex Profile I'm back! ...and still pulling my hair out. I made the change where I set no IRQ for video another irq for usb. This helped my network problem 0%. No help. I guess that this wireless network (raylink,buslink) is not going to work. If anyone has a wireless network that has worked well, please let me know. Otherwise, I guess no use in pursuing this further? Unless anyone can determine that it helps them. Thanks for all your posts!!!!! 01-16-2001 18:52:34

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) Programmer Profile OK Tex, it probably wasn't an IRQ issue to begin with. what network protocol are you using? I would personally recommend tcpip, as it is perfectly reliable.. 01-17-2001 09:15:24

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) Johnson Profile A couple of things.. I have a little program that I got called killcmos...it apparently resets your cmos and makes it refind everything..but I'm not Mr. recover from any little road block in 10 sec's like a lot of you..so if you want it..email me and I'll send it to you. The other thing is... there was a post that I had read before stating that someone had checked and found that it was actually a bug in the via chipset (I think that's right) that was causing the non-working output yet great input usb speeds... I don't know if any more research was done into this..but maybe pulling hair out for irq conflicts isn't the dragon we should be as concerned with slaying? jackson_1@hotmail.com 01-19-2001 01:00:07

This may help (modified 0 times) Johnson Profile This is the post I am referring to: Hello All, First... I've been chasing this USB problem (as it relates to the I-O) for several months now. And while I don't have a complete solution, I do have a workaround at least as far as networking is concerned. I have personally setup and networked 5 I-O's (of various version numbers) and all exhipted the same behavior. The real problem: - USB data corruption. After considerable effort researching this issue, I am convinced that the root of all our USB problems lies in a little known bug in the VIA MVP4 USB chipset that is present in most if not all I-O motherboards. Data sent OUT of the USB port is occasionally corrupted without generating an error message. Received data however is handled correctly. The workaround solution: - use ONLY TCP/IP protocol. There are many protocols that can be used for networking and unfortunetly the easist to setup (IPX/SPX and Netbui) are also the ones without significant error detection and correction. Any large files UPLOADED from an I-O using these protocols WILL BE corrupted without generating an error. However, with TCP/IP the corrupt data packet will be detected and the packet resent untill the file is delivered fully intact. Unfortunetly this causes a noticeable decrease in throughput. --(Side note:) I believe many people are somewhat mistaken when they say that thier USB to Ethernet connection is working perfectly. It may just appear that way for 1 of 2 reason: 1) Since most I-O's are used as terminals to connect to the internet, data flows largely INTO the I-O not out, so the problem is not nearly as noticeable if at all because corruption only happens with OUTbound data. 2) If they had the TCP/IP protocol installed from the first moment they started using their I-O then they would more than likely not ever realize the problem exists because its automatically corrected. That is untill they try to use some other USB device like a USB stereo amp or a USB external drive!! The correct solution: - correct the chipset I have written to VIA several times in the last six weeks and have not received ANY response. NONE! I think they know they have a huge problem here and they don't want to admit it. If you're as fed up with this bug as I am, jump over to their site and let them know. Maybe if enough of us speak up they'll do somethinig about it. http://www.viatech.com/contact/techsupport.htm Please feel free to respond to my conclusions. I welcome all opinions.

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) BigTex Profile I posted to via with your info! BTW, do I need to remove NETBUI (or other net protocols) completely, or just do not rely on it? BigTex 01-21-2001 07:13:30

RE:irq shared by usb and video: TCPIP mostly working... (modified 0 times) BigTex Profile Well... I got the TCPIP working for internet sharing very well. So far no problems. i removed netbui. File sharing seems to be having the same problems, though.... very slow... pc lockups.... FYI, all... BigTex 01-21-2001 12:41:05

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) asm_ Profile Hi, I think the assumption of a hardward flaw exist in VIA chipset still need a lot more proof. From Johnson's refered post, the original poster did not provide *any* evident to support such theory. Now only if we can find some one that owns a SMC or Linksys USB NIC to do a 700MB transfer with NetBEUI protocol. Then we can verify one way or the other. ASM 01-21-2001 22:51:38

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) YouBecha Profile I just turned off IRQ steering (winME pci properties) and noticed some improvement, I have both NetBeui and TCP/IP running. But is not perfect yet. http://www.geocities.com/mr_bubba_zanetti/ 01-22-2001 08:07:46

RE:irq shared by usb and video, I AM PULLING MY HAIR OUT! (modified 0 times) BigTex Profile I spoke too soon. Seems I am still having a few crashes, but TCPIP for net sharing (using WInPROXY) is still more stable than netbui. However file/print sharing still sux. 01-23-2001 08:31:56
