Thanks for the help guys, unfortunately I still couldn't boot NetBSD on my laptop. After searching a bit, it seems that many people have trouble installing NetBSD on regular laptops. Though, it works fine on desktops.
After disabling ACPI and MMC, I get an error with an assembly language instruction. I'm not qualified enough to make head or tails out of assembly language so I'll leave it for now.
HTML Code:
netbsd:sdmmc_needs_discover: testb $1x(some value I forgot), 20(%eax)
I might give openBSD a try after installing a qemu. So far freebsd is the only BSD variant that runs wel... ahem that installs just fine.
