choosing boot os9/ osx

[banished]

i saved yet another mac from the dumpster..
it's a power mac g3/300 160 megs of ram (i will probably throw in another 128 megs)
i formatted the hard drive and installed os 9.. now
i'm in the middle of installing osx on a second partition...
i understand osx is going to verrrrrrrrrry slow... but i have osx so why not..

anyways here is my question

how do i tell the mac which os to boot?
what keys do i need to hold down.... and to make things even more fun i'm using a windows keyboard... ( i could plug in a adb or usb if i have to.. but my desk has 3 keyboards on it already and i'm using a kvm because i'm out of room)

wow this was a long post for a simple question

If this is the beige G3, make sure that you make a partition for OS X that is at most 8 GB, otherwise the machine won't boot after the installation. With the Blue and White (B&W) Power Mac G3, you won't have this issue. The only issue you will have with a B&W Power Mac G3 is if it's a revision A which won't be able to use a hard drive as a slave on the IDE cable because of the built-in IDE controller (you should be able to bypass this issue with a PCI IDE controller). Revision B models will support a slave drive on the internal IDE bus.

As for how to tell the Mac which OS to boot, in OS 9 there's a folder called Control Panels. In there, you'll see a control panel called Startup Disk. Launch that and you can select which drive to boot from. In OS X, it's the same proceduew except that you will go to System Preferences and select the Startup Disk pane. As for which OS to select as the Mac is booting, hold down Option after the you heat the Mac startup chime. You'll see the operating systems you can boot from
