Power mac g5 how to enter bios

This is clearly a reference, and a useful one to those that understand the context. I have a macbook G4 with a newly installed hard drive. Any help would be greatly appreciated.

Even cleared out the PRAM. I have windows installed with bootcamp on my imac. I normally hold down the option key to boot with windows, and when I do that, the selection screen comes up where i press the arrow keys to choose which partition to boot from. Thats all fine and good, but recently, the selection screen has been coming up every time i boot, and when i select the mac icon, it shows the apple logo and then freezes.

Any ideas how to translate this in English: No, ok, ok, it is a good guide… I guess. I have a G5 with two sparate OSX operating systems defined each on its own hard drive both running Leopard. Until a few months ago, I could restart the system and depress the option key and I would get a screen showing my bootable HDs and I could choose which OS I wanted with different applications on each. I have to power it down and boot from the last bootable drive selected. How do I get that option back?

Any help would be apreciated. Anyone got anything?? It sounds like the computer is trying to boot from the network. That way next time you start up, it will use that disk automatically.

Doing that also might solve the problem with always booting up into Startup Disk selection. This should make the computer use Mac OS by default, with no special keys needing to be held. If you want to start into Windows, then holding down Option should still do the trick. Restart the computer without holding any keys, and see what happens. Hope that helps someone! When I turn on computer I get a blue screen only.
