A G4 will not boot from a i386 CD of any type, you need a PPC distro. http://cdimage.debian.org/debian-cd/7.1.0/powerpc/iso-cd/ PCI G4's can only use up to 256MB PC100/PC133 DIMMs (4x256=1GB max) AGP Models can use 512MB PC133 (4x512=2GB max, 1.5GB on the 3 DIMM models). I think you need low density DIMMs and don't mix parity types or use registered RAM. -----Original Message----- From: Cindy Croxton Electronics Plus Sent: Sunday, June 30, 2013 3:56 PM To: 'General Discussion: On-Topic and Off-Topic Posts' Subject: G4 update On Cory's suggestion, I tried just one stick of memory. Still no video. Tried the other 2 sticks, and it boots to question mark on either stick, but not both together. Pulled 2 sticks 265MB PC100 with same specs from drawer, it now boots to ?. Still will not boot the Live Debian 3.0.6 i386CD. Somebody give this guy a new home?
