On almost a dozen models tested now, everything works great. These were mostly laptops but a Dell Optiplex 360 and 380 booted fine. So far we have just had a problem with the HP 6005 Pro SFF desktop. With this model it hangs at "loading boot sector... booting...". This is using version 4.04.

Every version after that seems to allow the 2540p to boot. I thought maybe this information might prove useful in isolating what was changed in that version but maybe not. Every version I have tried with the 6005 has hung in the same spot.

When you did your testing, did you change pxelinux.0 versions along with 
memdisk? Their versions need to match.
