I have been trying everything possible to install Jaguar on my G3 AIO (500 MH with three 256M DIMMS and USB/Fireware PCI card). I have read elsewhere that others have successfully performed this operation. The internal HD is only 4G, however, I don't anticipate running much software from this unit and using as a "server" for some of my still very usable SCSI peripherals and as a USB printer sharer. Whenever I try to startup using the install disc the gray bitten apple logo appears together with the revolving bar. After a few seconds the screen garbles a bit and then freezes. I would appreciate any help that anyone might have. (NOTE: I have tried to use the Xpostfacto utility, along with removing the PCI card and extraneous RAM, none of which actions have been effective.)
