Hangs durning booting w/ additional serial port card

[videobruce]

I wasn't sure where to put this.

The MB (Foxconn N570SM2AA0 already has a serial port built in. I was having issues with the XP driver (nothing else available), so I purchased a PCIe serial port card and installed it. I did disable the on board port first.

I have two bootable drives and this happens with the orginal drive and the 2nd drive that I reloaded the O/S after I added the card. The O/S hangs 45 seconds, then continues to boot. I'm sure it's this serial card. Again this is with or w/o the driver installed running XP Pro w/sp2

The other possible related issue is com ports 1 & 2 are not available with the on board port disabled. Where in the registry can I regain these port numbers?

Hope this made sense.

You either have issues with the card's drivers,



...or you have issues with the add-on card itself.

My bet is with a defective add-on card

Well, I do have a 50:50 chance don't I?????

See if Knoppix or Ubuntu have the same problem.

It's durning the "Windows is starting up" screen. This card uses a MCOS 9901 chipset. The ports do work.

Again, this is with or without the drivers. Why is Com 1 & 2 not available?

Maybe it has to do with when you disabled the onboard port. Try re-enabling it and then try a few ways.

Again, try a bootable operating system to eliminate a driver issue from Windows or whatever one you are having issues with. My bet is still on a defective or damaged, corrupt add/on card because defective pci (pci-E also) peripherals usually cause boot-up lags and hesitations.

I disabled the on board serial port in the bios. If it was the card, why is it working? I'll try the other card.

Ok, I uninstalled the drivers, removed the card then rebooted. No change.
I disabled the 2nd SATA channels and the ethernet and firewire ports and still no change.

It still hangs on the "Windows is starting up" screen for 45 seconds.

Any ideas

You could try a boot using a Windows NT 4.0, 2000, XP or Server 2003 boot floppy disk (http://www.nu2.nu/bootdisk/ntboot/), or else Paul Komski's ISO for making the same boot disk as a CD (http://www.paulski.com/bootcds/bootxp.iso).

If the same problem still exists when using one of these disks it would confirm that the problem is with the files in the Windows folder.

Perhaps the delay results from a difficulty finding settings in the registry.
So I wonder whether defragmenting the registry would help?

This UBCD4Win "List of Files" help file gives at "Contents->General Information->The PC Boot Process for XP" a rather good description (http://www.woofiles.com/dl-171026-XSPLeeaH-UBCD4WIN.chm).
The problem may arise at or near "Kernel Initialization" I guess.
