problem reading PXELinux's code
...tore ES:DI and BX on PXE stack, which points to PXE
parameter block and PXE opcode correspondingly. Then we should call !PXE's
EntryPointSP to call specified PXE API, but why we use *call 0:0* here?
What does physical address 0x0 have?
Can anyone who can please explain it?
Thanks and regards,
zenghui
