I should note that any doubled \\ that appear in the strings are really single \, they are just escaped OCaml strings. It might help to fire up the OCaml interpreter: $ rlwrap ocaml OCaml version 4.02.3 # open Printf;; # printf "PCI\\VEN_1AF4&DEV_1001&REV_00\n";; PCI\VEN_1AF4&DEV_1001&REV_00 - : unit = () # let oem_inf = "oem1.inf";; val oem_inf : string = "oem1.inf" # printf "(a)%s,%%rhelscsi.devicedesc%%;Red Hat VirtIO SCSI controller\n" oem_inf;; @oem1.inf,%rhelscsi.devicedesc%;Red Hat VirtIO SCSI controller - : unit = () Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-top is 'top' for virtual machines.

I went back to the original Windows guest that I used for getting the registry changes, and found that I had transcribed these two strings incorrectly.
