BIG problem with IO conflict on BIOS

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!

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.
