CHANGING TO ANOTHER (SONNET) USB II PCI CARD SOLVED THE PROBLEM.! I SWEAR BY SONNET. THEIR STUFF WORKS. IN OVER 12 YEARS I'VE HAD BUT ONE PROBLEM WITH A SONNET PRODUCT .... AND A TEN MINUTE PHONE CALL SOLVED THAT ONE. (To install a G3 500MHz daughter card into a PowerComputing Power Center Pro you must remove the Cache Dimm.) The manual didn't cover that. The second one I bought came with a marvelous thick professionally written manual.
