This is on my beige G3. I'm using the latest firmware version from adaptec. The OS installs fine, but I go to restart and it hangs at the MacOS 9 splash screen almost immedietly (no extensions have a chance to load). The odd thing is, disabling extensions allows me to start-up. Changing the startup disk to another drive with OS9 on it doesn't work either - it ignores that drive and boots off the UW drive with the same symptoms. The only way im able to boot up in OS9 successfully (with extensions) is by pulling the card! Note that there are no third party extensions installed; i did a clean installation (and zapped the PRAM). Please, if you have any ideas, let me know.
