Example : I had no idea that the 0x055AA wasn't always looked for from the BIOS with regards to removable media. I always was informed it will always be looking for that signature no matter what drive you use. Although he did state it is not always reliable. Still, this is knowledge that I needed long ago when I was playing with VirtualBox. It didn't act right one day and I thought it was just a bug. Turns out that VB actually did what some of those BIOS did which was look for the first byte to see if its greater then 0x06h. I never knew this !! So glad I got this book now !!

The book goes on to explain memory managers and shows you a basic Round Robin version. It's well worth the read.
