Running VirtualBox VM host on ReadyNAS Pro

FYI

For those of you wishing to install Windows 2K/NT/XP it appears that the Windows Intel SATA driver "F32.IMA" is no longer available from Intel as referenced in chirpa's Virtualbox WinXP SATA install link Windows SATA Support. Nor could I find it anywhere on the web. The work around to creating a floppy image of the SATA drivers is described in How to install Windows 2000/XP/2003 guests with SATA support

To create the image on the Pro I needed mtools:

apt-get install mtools

I then copied the zip file from the Option 3b - unofficial drivers location and put them into my working floppy directory.
From there I followed the recipe to make the floppy image.

mkdir floppy
cd floppy
# copy the XP AHCI v7.0.0.1020 for ICH8 Driver zip to the target folder
cp <source-path> .
unzip AHCI_v7.0.0.1020_for_ICH8.zip
dd if=/dev/zero of=./ich8.img bs=1k count=1440
mformat -i ich8.img -f 1440 ::
mcopy -i ich8.img "AHCI v7.0.0.1020 for ICH8"/* ::

Once I had the floppy image I was able to complete the creation of my WinXP guest OS VM described in the Windows SATA Support page.
