Can't boot!

Help! I've been upgrading my Beige G3 minitower 266, first a Fastmac 500mHz G4, and more RAM. Everything was working fine, so I was going to add an ATI Radeon 9200 video card. I thought that I would do a drive check, so I put in the OSX 10.2 disk, set the Startup drive to the disk, rebooted, and then ran the Disk utility. SO far so good.

When I went to restart, it would only boot to the disk, holding down the mouse button, option key, nothing. I then thought that I could zap the PRAM to reset the start-up drive. WHen I did that, no extra chimes and only a blank screen. Now it won't even boot to the CD. Only gray.

Any ideas?

Thanks!

 

Thanks for your reply!

When I try to zap the PRAM, I get no extra chimes. I get the first one, but no more.

I took out the new memory, pushed the PMU and now the machine boots into the OS 9.2 desktop, but even though the mouse moves, I can't select anything on the desktop, and key commands, such as command-n for a new folder produce no result. I'm starting to think the ADB I/O is messed up, perhaps that is why the PRAM salute is not working.

Funny, I can get the machine to reboot with cntrl-command-power key combo.
