I have two identical MB's both using XP Pro w/sp2
They are the Foxconn N570SM2AA.

With two different serial devices (a FTA receiver and a RF signal level meter) I have to first disable the serial port, then re-enable it to be able to communicate with either device. If I don't, I get a error message.

My previous MB had a nForce2 chipset and used 2k. I had no issue with two different FTA receivers using the serial port.

With another piece of test equipment, there is a different problem. The software locks up after 5 seconds after hitting the 'start' button to try to connect with the device (after the s/w is opened). I believe this is aseparate issue since the disable/enable doesn't help. (There was no issue with the previous MB and O/S.)

Any ideas about why I have to disable, then re-enable the port everytime?
BTW; no conflicts in DM and it is the stock Windows driver that is loaded.
 
If I disable then re-enable the port the 1st time, there is no reboot message. If I do this a 2nd time, I get the reboot message.
On my other bootable drive, I alway get the reboot message.

Any idea why?
