ok i've downloaded the voodooHda files, as soon as I install the VoodooHDA.kext (using kext helper) it says cross fingers and reboot,BUT it quickly goes to grey screen that says "reboot by hoding button down for 5 seconds,,,,,,," upon reboot it crashes....

Toshiba Satellite P-105

then remove the voodooHDA.kext.

Bootup with -s (single user mode)
then:

/sbin/fsck -fy
/sbin/mount -uw /

cd /System/Library/Extentions
rm -R VoodooHDA.kext
touch /System/Library/Extensions.mkext
reboot
