| In many cases, older third-party PCI adapter cards using out-of-date firmware are at fault. When used with a 700 MHz or faster Encore/ZIF G4, a PCI card that does not have up-to-date firmware can cause the issues described here.
To confirm whether a PCI card is at fault, you will need to remove each PCI card from your computer, one at a time, and reboot the computer after each card is removed. When your computer boots successfully and operates without crashing while a particular card is removed, it is likely that you have isolated the card causing the problem(s). Be sure to take all precautions against static discharge during this process, or you may inflict permanent damage to part, or your entire computer. This process will also help you determine whether multiple PCI cards are at fault. If your system\u8217 s boot drive is attached to a PCI card, you will need to boot from a drive attached to the internal ATA bus or a Mac OS installation CD to check that card. When removing any video card, you will need to attach your monitor to the video port on the logic board. If your computer does not have onboard video, you will need to install a known-compatible PCI video card to complete the testing.
To solve this issue, update the firmware and use the latest software with the PCI card(s) in question. You can usually locate the latest firmware and software on the manufacturer\u8217 s web site; contact the manufacturer directly if you can\u8217 t find what you need. Remove the Encore/ZIF processor card from your computer, reinstall the original processor, and then update the firmware and install any software following the PCI card manufacturer\u8217 s instructions. Once this is done, you may reinstall the processor upgrade and your system should operate without issue. If there are no new updates and your PCI card is already running the latest version firmware, you should replace the card. |
