i tried to install Snow Leopard on my HP Pavillion DV7-1298eg ... but everytime i try to boot the chameleon bootloader i got the "EBIOS READ ERROR 0x01" 4 times ... after that my i get an Kernel Panic (panic(cpu 0 caller 0x0019c352)) and the installation stops.

Any ideas where this error comes from?

I used this tutorial: SUCCESS: HP Pavilion dv7 Intel + Snow Leopard 10.6 - InsanelyMac Forum
and this: myHack Installer

But it ends with the same error everytime.

Hope you can help me.
