Centos 6.3 installed via pxe/tftp on Windows 7

[billygoat]

I'm having an issue installing CentOS 6.3 onto a Windows 7 host using PXE. Here's my setup.

I have a VM named "asdf"

I have put an asdf.pxe file with the following under vboxhome/TFTP

Code: Select all

DEFAULT asdf
PROMPT 1
TIMEOUT 5

LABEL asdf
    KERNEL asdf/vmlinuz
    APPEND asdf/initrd.imgs vmkopts=debugLogToSerial:1 mem=512M ks=<secret_url>/ks.cfg

I have installed "Oracle VM VirtualBox Extension Pack" and tried this with every network card...

Under TFTP there is another folder containing the files mentioned above in the .pxe file. The ks file is being served up on an apache server.

When I start up the box, it freezes with the following being the last log output:

Code: Select all

Any idea what the "BIOS ... not yet supported" line is? Any idea how to fix this?

Sorry, I forgot to put the version of VirtualBox that I'm using. I'm using 4.2.6 r.82870. Do you need anything else?
