Does the Extensions.mkext just get OSX86 to boot up or does it have drivers in it to?

I'm wondering if I need to add a .kext into my Extensions file to get rid of my

"Disk Erase failed: Input/output error"

because erasing my IDE hardrive before my install works but it doesn't work on my SATA hardrive.

I know I've posted a thread about this before but I'm trying to narrow it down to find the problem.
