I would like to reprogram a EEPROM, however it seems that my Serial Port does not provide power when I enter Windows XP. Under Linux, the JDM PIC programmer's LED lights up, however I need to use Ponyprog in Windows.
I see there is power to the programmer just until I enter Windows.

Try to see in the device manager if windows does not turn off the port to save energy.
It's the only option I see for the moment. I try to look further if it's not the problem.

Thanks for the suggestions. I tried using the COMdisable tool from Microsoft, but it has not changed the status of the status of the port. It is still visible in the Device Manager as serial port COM3.
Needless to say, the BIOS does have the serial port enabled.
Unfortunately I have the same results using this Thinkpad A31 on a dock!

Apparently it's a problem of I/O port. Windows XP have a strict control over I/O port.

Hope it will help
