I like to feel that I make these mistakes to ensure others are paying attention. However, it does mean that I can just put an address in there and increase the length field to 32 bits. Much rejoicing. Will fix and resend tomorrow (Friday is in-office-away-from-test-machine day). > I don't like the chaining and would prefer the descriptor to refer to an > array of page descriptors.

I'll certainly consider your patches, although I suspect that managing descriptor pages will make things ugly enough to cause you to reconsider. Thanks!
