I have a quicksilver 2001, dual 800. I installed an AGP nvidia geforce 6200. The software requirement for the card is10.4.3. I have 10.5.8, 10.4.11, and 9.2.2 installed on this machine. since installation of the card, only leopard boots. tiger kernal panics (shows me the picture of the power button and tells me to restart) within seconds of the gar apple. I tried booting off of the tiger install dvd, and panther install cd. same thing happens with those. it seems only leopard likes this. I am in need of classic so i need to be ble to use something older than leopard. Any ideas? Thanks in advanced.
(btw the card works perfectly in leopard)
It may be a case of a missing or corrupt file......
I would run the OS X 10.4.11 Combo Update again.
You can likely do it from FW TDM, or at least, put the downloaded combo update onto the drive.
Then, boot to Safe mode and run the update.
