Sometimes a BIOS upgrade will change the way hardware is recognized,
thus triggering a need to reactivate.
You might want to try a couple of things:
1. Undoing the BIOS upgrade. Most BIOS flash programs provide for the
automatic saving of the old BIOS data so it is relatively simple to
run the flash program again and put the old BIOS back. But BIOS
upgrades are always tricky and a power outage at the wrong moment can
be disastrous.
2. Do a "repair install" of Windows XP. This is what is required when
a motherboard is replaced by a different make/model and it may be that
your recent BIOS upgrade has had an effect similar to a motherboard
replacement. See

for detailed instructions.
But before you do that you probably should create a new Windows XP
install CD with SP2 splipstreamed into it. Post a response back here
if you need help with this.
Good luck
