IIRC, the very last version of the Quicksilver (2002?) could support large drives, the earlier versions of the Quicksilver could not. Lars or MacDoc or JohnClay will probably have the details to hand --- Guys?

Apple Power Macintosh G4 800 (QS 2002) Specs (Quicksilver 2002 - M8705LL/A) @ EveryMac.com

Apple: "The BootROM of Power Mac G4 (Mirrored Drive Doors), Xserve, Power Mac G5, and any other model introduced after June 2002 can accommodate these larger drives."

Alternatively, you can buy some software (from Insite?) that enables large drives.
