In addition to Mike's comments / questions:

1) Did you check your known-good Win2k system and see if someone had run SDConfig
before? And if so, what are the parallel port, "Emulator Port Speed", and "Disable
Emulation Polling" settings, and a) are they the same on your WinXP system, and b)
does SDConfig pass on the WinXP system?

2) Did you try running xdsprobe?

Regarding Mike's question about "stopping in the same place": one trick I used
before (don't know if this works in C3x/C4x CC 4.10) is to use the mouse to
intermittently grab the title bar of the small download progress box. Keep pressing
and releasing the mouse button; sometimes you can get lucky and figure out what's the
last address range that is successful and which range fails. Knowing the address
range can be useful because CC/CCS downloads code and data in sections; i.e. the
sections that you see in the .map file and COFF .out file.
