    BIG problem with IO conflict on BIOS

    Locked

    by threenorns ·

    situation: virus required format of hard drive by user. windows disk NOT accessible.

    upon attempting to talk the user through a reinstall from the disk, he kept saying it wasn’t booting and that the computer was giving an error message. what hetold me sounded like the BIOS settings had been re-arranged, so i advised he reinstall system default settings on the BIOS (an AWARD BIOS approximately three years old, motherboard type unknown, BIOS type unknown, user VERY useless and prone to either panic or to leap ahead on assumptions).

    upon loading system default settings, a conflict appeared at 2F8h (COM2) and the CD-ROM stopped working, or would working only intermittently.

    after another hour of going nuts, the user FINALLY admitted that his winCD was not really a setup disk, just a backup copy.

    i am now trying to resolve this stupid COM2 conflict: disabling it in the BIOS renders the CD-ROM useless. enabling it restores unreliable, intermittent function. i can’t access the machine myself (it’s over 200 miles away) but any help would be appreciated.

    thanks!

      1.Have you tried going into BIOS and changing Plug’n’Play IO allocation to manual and reassigning the IO’s? Care must be taken when doing this as certain devices can only be assigned to certain IO’s therefore choice is limited.
      2.Win98 can only carry so many devices. Is your client’s system overloaded with devices?
      3.I have experienced an IO conflict. Although following the manufacturers ReadMe file re: manual allocation in Hex. I found that the only way to resolve the conflict was to reinstall Windows. In many ways Win98 is inflexible and can cause it’s own problems.
      4.Usually with IO conflicts Win98 offers a trouble shooting wizard which gives the option of disabling one device to allow use of another i.e disable infrared to enable Com2. This is not a solution but will allow use of Com2 until the problem is resolved.

        hi — win98 isn’t the problem because there IS no win98. reassigning IO’s manually didn’t help, either — the conflict still comes up, but if i disable COM2, the CD-ROM disappears (along iwth the conflict).

      With this situation,I would recommend…
      1/setup disk,bootdisk(of course)
      2/a complete Fdisk and format
      3/load windows….everything hereon in should be a clean load. The fix

        This way if something does go wrong,you,ll know enough to investigate the bios/cmos settings…….While in there disable anti-virus as sometimes windows is regarded as an intruder.

        been there, done that: the startup disks are HORRIBLE — they keep demanding windows files. i created a set of DOS-only disks and all hell broke on the reboot!

      1)Upon booting the system in safe mode,choose the step by step configuration and answer Y to the end of each line.This may restore the configuration to original state.
      2)If he can boot the system and go to the CMOS control panel,he can choose the F6 key to restore the BIOS defaults,if the cd-rom is connected to the sound card then he will need the drivers loaded to access the cd-rom,it sounds as though he has changed the I/O port for the sound card,in that case it would be wise to go through the control panel and find any exclamation marks and reinstall the sound card and updating the drivers.
      3)The bottom line is he has to use his owners manual or another computer to reset the ports in the CMOS panel,back to original state before he started making changes.

        not possible: no windows installation disk, no manuals, no nothing. he’s a newbie and was offered the computer very cheap, but the previous owner insisted on keeping all program disks and there weren’t any hardward manuals to go with it.

        he’d already formatted the hard drive before he called me, and the whole mess arose when he was reluctant to tell me he didn’t have an actual installation disk — just a backed up copy of his hard drive.

      I’ll agree with answer #3, re-storing defaults should have resolved the conflict, I see this was tried.

      Is it possible the Virus also hit the BIOS? On boot up Award Bios gives you the version prior to checking for any thing else. Re-flashing may help resolve the conflict.

      Is CD internal or external? Clear from BIOS and unseat Modem card to “free Up” com 2 and get the system back onto the hard drive?

      Manually assigning the I/O for the CD (IRQ 15 and I/O 0170-0177 for example) did not work. Did he SAVE the changes? Have him reboot and verify the changes were saved.

        yes. the virus hitting the BIOS did occur to me: he didn’t even check WHAT virus it was, nor did he fdisk — just blithely went ahead with a format.

      I’m confused. At this point, is there any operating system on the machine or is it just bootable? And what does COM2 have to do with the CD-ROM?

      Is there a jumper on the motherboard he can pull to reset the BIOS defaults?

      Try pulling everything from the system except video card and cd-rom (sound cards, modems, zip drives, etc) and see if that helps.

        you’re confused? i’m going *nuts*!

        at this point, the machine will boot BUT: if COM2 is enabled, it gives a conflict error message at 2F8 (press F1 to continue) and the CD-ROM is accessible after many tries and if he tries to read from it, forget it — it cuts out after random intervals. if he disables COM2, the conflict message does not appear, but neither does the CD-ROM — the light doesn’t go on, the drive is not assigned, nothing.

      I’m also having a problem trying to figure out what COM2 has to do with the CD-ROM, but, I’m taking your word for it. The only thing I could suggest was pulling (at least) the modem, being sure that the IDE cables are routed correctly, and trying again. Something nags me about IDE controllers, and this sounds like one of the things that is going wrong.

        as of last thing last night, the modem was out, as was the sound card.

        tonight, i call him up and we’ll see what happens.

      Possibly, just possibly, might the CD-ROM be on a separate controller that is a combination sound-card, modem and IDE CD-ROM controller?

      Other than that, I just am not getting the relationship between COM2 and the CD-ROM drive. It’s either that or an external CD drive.

      You can break it down to just the basics, hard drive, floppy drive, CD drive and video board and see if you can load it then. I’d just about say that a sound card or winmodem could be sharing the IRQ with the hard drive controller.

      Seriously, without more functional information on the computer, I would recommend that you have the user ship the PC to you and let you work on it.

        i have no idea. trying to get information out of this guy is like reliving the Clinton/Lewinski fiasco, with about much the same aura. i’ve already suggested he ship the machine up, but he doesn’t want to do that either — gods only know what he’s covering up THIS time!

        quite frankly, tonight is the last attempt. if it doesn’t get fixed tonight by pulling ALL but the basics and at least getting windows back on the drive, then i’m refusing to do any more remote support on it. i’ve been on the phone with this guy for over 13 hours (all told), and i’m about at my limit.
