AHCI Doesn't Work

[Nobody III]

Okay. I'll try it on my computer (and on VirtualBox). Thanks for telling
me. I thought that I'd have to wait to be able to run Genode on my
computer. Now the only hardware support missing (that I'm aware of) beside
the proper configuration is wireless (with WPA2-PSK support) and printer
support.
