Setting up a c-diff would be tricky on my end. The CVS checkout doesn't actually work as described in the linuxbios web page. I had to download the daily snapshot, then extract that into my own cvs server, then check that out to get the code. However I then started checking stuff back in since it was already setup...so what two trees can I diff now? Anyway all the relavent code was included in the email.
You wouldn't want to change the MEMSIZE stuff, it is a different interrupt. You'd be mixing different things that should stay separate. I think how I've implemented it is the way to go.

oh! how embarrasing!
This is good stuff, and you're implementing it just right.
IF you want to send a c-diff for the int21 stuff I'll apply it.
What I'll probably change is just have the INT21HANDLER call memsize() which works on all platforms.
