Well I upgraded my 7200 to a 7300 by upgrading the logic board, not realizing that they used different power supplies. So I got a 7300 power supply. Then I realized I needed VRAM. So I got VRAM. I also bought a PRAM battery for it too.

All I get is a chime. No video or anything. I was hoping the VRAM would solve this. I JUST realized that there is a ROM DIMM slot on the motherboard, and it looks like there are no ROM chips soldered to the board. If it doesnt have ROM, how did it give me a boot chime?

So do I need this ROM DIMM, or is there another explanation for this problem? I thought all Power Macs of this era had their ROMs soldered to the logic board.

I'm starting to think I would have been better off just buying the Sonnet Crescendo G3/7200...
