I was browsing for ways to store files and programs off a Hard Drive or SSD and I found this little gem here. http://esec-lab.sogeti.com/static/publications/11-recon-nicreverse_slides.pdf, a little guide on how to store, a rootkit on Broadcom NetExtreme network cards. It's a little old and but I've written some test rootkits and they work perfectly (at least so far), perfect for getting past an antivirus (Who scans network cards for infections?) especially as a troll for a your friends furiously trying to remove your rootkit.
