I picked up a Performa 6400/200, my old college computer, off of craigslist. It had no hard drive, so I swapped out the hard drive for another I had laying around. Booted up fine, and I moved on to my final plan - dual booting Mac OS 9 and BeOS. I got the drive partitioned, reinstalled OS 9 on there and got ready to install BeOS. I started up the machine, got the startup chime, but no video. I tried a different monitor, as well as a different adapter (6400 didn't have VGA out, so I used two different types of adapters. Still no video out.
I removed the video-in PCI board, just in case. Tried zapping the PRAM, no change.
The board looks clean, caps not bulging and don't see any signs of leaking. The original PRAM battery was dead, so I removed it and I still get the boot sound. There was a 3x AAA battery holder connected to the PRAM battery connector, so I threw 3 AAA batteries in there and I'm getting 4.1v at the connector, which is a bit lower than the 4.5v of the original battery. Still no video on boot.
Any ideas on what to check next?
