Dual boot help

After updating to newer BIOS, Leopard will not boot anymore without KP. Reinstalled and installed Chameleon again, KP again except using BootThink that came with iATKOS. So today I installed SL and it is fine until I installed Chameleon v2 rc1,2,3 at different occasions and SL will KP at boot. Used BootThink and same result. What weird is that it will boot using USB with Chameleon rc1.

After tinkering with it for the afternoon I installed Chameleon v1 with efiv9 boot file. It boots fine now but there's no more Windows option. Is it possible to dual boot using that bootloader?

TIA.

I feel very stupid. EasyBCD fixed it.

Install is ok except for PS2 k/m are not working. I installed voodooPS2 and still no go. Other than that everything is going great.

try the PS2 drivers off a DVD, like the iPC DVD, Voodoo PS2 didnt work for me either, so I used the one from the disc.

You can make use of ApplePS2Controller.kext & AppleACPIPS2Nub.kext - they are universall (i386, x86_64 & ppc) and work with allmost all devices.

If you like, you can use this pkg to install them:

I wil try your suggestions, fellas. For the meantime, I found my trusty PS2-to-USB dongle and she is a happy snow kitty.
