BroadCom NICS- W2003

hello,

i'm trying to up grade PE 2650 tag CH0TP21 from NT 4 to W2003. i've got all the firmware, ESM, etc all updated in NT and am ready to install 2003.

i can't get 2003 to install, the BroadCom NetXtreme Gigabit NICs aren't compatible. I tried to update the drivers but NT isn't letting me do that (because they're 2003 drivers?)
