[syslinux] PXE menu file problem

[behrad at rayavaran.com]

As a matter of fact, pxelinux can execute pxe.mnu if you named it pxe.0. The pxe.0 menu appear but when the user choose any floppy image file or even want to localboot from the menu, system resets. This is not happen when pxe.mnu is directly loaded without intermediation of pxelinux.0.

I think there is an important bug in pxelinux. Maybe it hooks some interrupts and doesn't roll them back or something similar in memory location it loads.

Learning is enjoyful but you will enjoy it more if you can do the job! I hope HPA helps!

Yes, but why?

You did a nice expriment.
You learned that the MBA can execute "pxe.mnu" and also "pxelinux.0"
You also learned that pxelinux does not execute "pxe.mnu".
